Answers

Answer 1

The smallest angle measures 15 degrees and the other non-right angle measures 75 degrees.

To find the measure of both angles in a right triangle with the given conditions, we will use the information provided:

Let x be the measure of the smallest angle. The problem states that the measure of one of the small angles is 30 less than 7 times the smallest angle, which can be written as:

Other non-right angle = 7x - 30

Since this is a right triangle, the sum of the two small angles must be 90 degrees (because the other angle is 90 degrees, and the sum of angles in a triangle is 180 degrees). So, we can set up the following equation:

x + (7x - 30) = 90

Now, solve for x:

8x - 30 = 90
8x = 120
x = 15

So, the smallest angle is 15 degrees. Now, we can find the measure of the other non-right angle:

Other non-right angle = 7x - 30 = 7(15) - 30 = 105 - 30 = 75 degrees

In summary, the smallest angle measures 15 degrees and the other non-right angle measures 75 degrees.

Para medir lo largo de un lago se construyeron los siguientes triangulos semejantes, en los cuales se tiene que : AC = 215m, A 'C= 50m, A'B=112m. Cual es la longitud del lago?

Answers

using the given similar triangles, the length of the lake is approximately 26.05 meters.

We have,

In the given similar triangles, we have the following information:

Length of the longer side of the larger triangle: AC = 215m

Length of the longer side of the smaller triangle: A'C = 50m

Length of the corresponding shorter side of the smaller triangle: A'B = 112m

Let's denote the length of the lake (the longer side of the smaller triangle) as x.

Now, we can set up a proportion between the sides of the two triangles:

AC / A'C = A'B / x

Substitute the given values:

215 / 50 = 112 / x

Now, solve for x:

215x = 50 * 112

Divide both sides by 215:

x = (50 * 112) / 215

x ≈ 26.05

Thus,

Find the values of a and b, if the function defined by f(x) = x^2 + 3x + a , x <= 1
bx + 2, x >= 1 is differentiable at x = 1

Answers

To find the values of a and b, we need to ensure that the function is differentiable at x = 1. Thus, the function defined by f(x) = x^2 + 3x + a, x <= 1 and bx + 2, x >= 1 differentiable at x = 1 are a = 3 and b = 5.

First, we need to check that the function is continuous at x = 1. Since the function has different definitions for x <= 1 and x >= 1, we need to check that the limit of the function as x approaches 1 from both sides is the same.

Limit as x approaches 1 from the left (x <= 1):

f(x) = x^2 + 3x + a

lim x->1- f(x) = lim x->1- (x^2 + 3x + a) = 1^2 + 3(1) + a = 4 + a

Limit as x approaches 1 from the right (x >= 1):

f(x) = bx + 2

lim x->1+ f(x) = lim x->1+ (bx + 2) = b + 2

For the function to be continuous at x = 1, these two limits must be equal.

4 + a = b + 2

a = b - 2

Now we need to check that the derivative of the function at x = 1 exists and is equal from both sides.

Derivative of the function for x <= 1:

f(x) = x^2 + 3x + a

f'(x) = 2x + 3

f'(1) = 2(1) + 3 = 5

Derivative of the function for x >= 1:

f(x) = bx + 2

f'(x) = b

f'(1) = b

For the function to be differentiable at x = 1, these two derivatives must be equal.

5 = b

Substituting b = 5 into the equation we found earlier for a, we get:

a = 5 - 2 = 3

Therefore, the values of a and b that make the function defined by f(x) = x^2 + 3x + a, x <= 1 and bx + 2, x >= 1 differentiable at x = 1 are a = 3 and b = 5.

Russo is trying to find the area of the lake in his neighborhood. He sees a duck (point C) and uses a tape measure to find that the duck is 16 feet from the point of tangency (point B). He also measures out that the duck is 8 feet away from the edge of the lake (in the direction of A).



Using this information, what is the radius of the lake?

Answers

The radius of the lake is approximately 17.89 feet.

To find the radius of the lake, we can use the information given and apply the properties of tangents to circles.

Since point B is the point of tangency, the line segment AB is tangent to the circle. A radius drawn to the point of tangency, in this case from the center of the lake (point O) to point B, will be perpendicular to the tangent line (line AB).

Now, let's use the given measurements. The distance from the duck (point C) to the point of tangency (point B) is 16 feet, and the distance from the duck (point C) to the edge of the lake in the direction of A (line AC) is 8 feet. We can form a right-angled triangle OBC with the given information.

Since OB is perpendicular to AB, we have a right-angled triangle with legs CB and OC. Using the Pythagorean theorem, we can find the length of the hypotenuse, which is the radius of the lake:

OC^2 + CB^2 = OB^2
(8 feet)^2 + (16 feet)^2 = OB^2
64 + 256 = OB^2
320 = OB^2
OB = √320
OB ≈ 17.89 feet

So, the radius of the lake is approximately 17.89 feet.

The distance between san antonio and houston is 190 miles. nicholas and rose each drove 2/5 of the total distance. if charlie drove the rest of the distance, how many miles did charlie drive?

Answers

Charlie drove 90 miles between San Antonio and Houston.

Nicholas and Rose each drove 2/5 of the total distance (190 miles). To find the distance they drove together, multiply 190 miles by 2/5 twice (once for each person):

190 x (2/5) = 76 miles (Nicholas)
190 x (2/5) = 76 miles (Rose)

Together, Nicholas and Rose drove 76 + 76 = 152 miles. To find the remaining distance Charlie drove, subtract this combined distance from the total distance:

190 miles (total) - 152 miles (Nicholas and Rose) = 38 miles (Charlie).

Charlie drove 90 miles between San Antonio and Houston, as Nicholas and Rose each drove 2/5 of the total 190-mile distance, resulting in 152 miles combined, leaving 38 miles for Charlie to cover.

Alexandria rolled a number cube 60 times and recorded her results in the table.

What is the theoretical probability of rolling a one or two? Leave as a fraction in simplest from​

Answers

The theoretical probability of rolling a one or two on a number cube is 2/5 or 0.4.

To find the theoretical probability of rolling a one or two on a number cube, we need to determine the number of outcomes that correspond to rolling a one or two, and divide that by the total number of possible outcomes.

From the table, we can see that Alexandria rolled a one or two a total of 24 times out of 60 rolls. This means that the probability of rolling a one or two is: P(1 or 2) = 24/60

Simplifying the fraction by dividing both the numerator and denominator by the greatest common factor, we get: P(1 or 2) = 4/10

This can be further reduced to: P(1 or 2) = 2/5

Therefore, the theoretical probability of rolling a one or two on a number cube is 2/5 or 0.4.

In summary, the theoretical probability is the expected probability of an event occurring, based on mathematical reasoning. Here, we used the number of favorable outcomes to calculate the probability of rolling a one or two, and expressed the answer as a fraction in simplest form.

Find the volume of the solid generated by revolving the region enclosed by x= v5y2, x = 0, y = - 4, and y = 4 about the y-axis.

Answers

To find the volume of the solid generated by revolving the given region about the y-axis, we can use the method of cylindrical shells.

First, we need to sketch the region and the axis of rotation to visualize the solid. The region is a parabolic shape that extends from y = -4 to y = 4, and the axis of rotation is the y-axis.

Next, we need to set up the integral that represents the volume of the solid. We can slice the solid into thin cylindrical shells, each with radius r = x and height h = dy. The volume of each shell is given by:

dV = 2πrh dy

where the factor of 2π accounts for the full revolution around the y-axis. To express r in terms of y, we can solve the equation x = v5y2 for x:

x = v5y2
r = x = v5y2

Now we can integrate this expression for r over the range of y = -4 to y = 4:

V = ∫-4^4 2πr h dy
 = ∫-4^4 2π(v5y2)(dy)
 = 80πv5

Therefore, the volume of the solid generated by revolving the given region about the y-axis is 80πv5 cubic units.
To find the volume of the solid generated by revolving the region enclosed by x = √(5y²), x = 0, y = -4, and y = 4 about the y-axis, we can use the disk method.

The disk method involves integrating the area of each circular disk formed when the region is revolved around the y-axis. The area of each disk is A(y) = πR², where R is the radius of the disk.

In this case, the radius is the distance from the y-axis to the curve x = √(5y²), which is simply R(y) = √(5y²).

So the area of each disk is A(y) = π(√(5y²))² = 5πy²

Now, we can find the volume by integrating A(y) from y = -4 to y = 4:

Volume = ∫[A(y) dy] from -4 to 4 = ∫[5πy² dy] from -4 to 4

= 5π∫[y²2 dy] from -4 to 4

= 5π[(1/3)y³] from -4 to 4

= 5π[(1/3)(4³) - (1/3)(-4³)]

= 5π[(1/3)(64 + 64)]

= 5π[(1/3)(128)]

= (5/3)π(128)

= 213.67π cubic units

The volume of the solid generated by revolving the region enclosed by x = √(5y²), x = 0, y = -4, and y = 4 about the y-axis is approximately 213.67π cubic units.

The first number is 30% less than the second number and the third number is 40% more than the second number.What is the ratio of the first number to the third number?

Answers

Let's assume the second number to be 'x'.

According to the problem, the first number is 30% less than the second number.

This means the first number will be (1-30/100)x = 0.7x

Similarly, the third number is 40% more than the second number.

This means the third number will be (1+40/100)x = 1.4x

Now, we are asked to find the ratio of the first number to the third number:

Ratio of the first number to the third number = 0.7x/1.4x

Ratio of the first number to the third number = 1/2

Therefore, the ratio of the first number to the third number is 1:2.
Let second number be x

First number Is 30% less than 2nd number. Therefore the 1st number is = 70%x = 0.7x

3rd number. is 40% more than 2nd number. Therefore
3rd number.= x + 40%x = x+0.4x = 1.4x

Using the linear model, we can predict that a 100 mg dose of the experimental drug would cause a change in the patient's blood pressure of 540 mmHg.

What is equation?

An equation is a mathematical statement that expresses the equality of two expressions. It consists of two expressions, one on the left side and one on the right side, which are connected by an equals sign (=). Equations are fundamental to mathematics, and are used to solve many problems. In addition, equations can also be used to describe physical laws, such as Newton's law of gravity.

10 + 2(20) + 3(30) + 4(100)

= 10 + 40 + 90 + 400

= 540 mmHg

The linear model suggests that a 100 mg dose of the experimental drug would cause a change in the patient's blood pressure of 540 mmHg. This can be seen by using the linear equation 10 + 2x + 3x + 4x. Here, the first coefficient of 10 represents the change in blood pressure for a 10 mg dose, the second coefficient of 2 represents the change in blood pressure for each additional 10 mg dose, the third coefficient of 3 represents the change in blood pressure for each additional 20 mg dose, and the fourth coefficient of 4 represents the change in blood pressure for each additional 30 mg dose.

For example, if the patient was given a 40 mg dose, the equation would be 10 + 2(20) + 3(30), which would yield a change in blood pressure of 140 mmHg. Similarly, if the patient was given a 50 mg dose, the equation would be 10 + 2(20) + 3(30) + 4(10), which would yield a change in blood pressure of 190 mmHg.

Therefore, using the linear model, we can predict that a 100 mg dose of the experimental drug would cause a change in the patient's blood pressure of 540 mmHg.

= 540 mmHg

The linear model predicts that a 100 mg dose of the investigational drug will raise the patient's heart rate by 540 mmHg.

Using the linear equation 10 + 2x + 3x + 4x, this may be observed. In this case, the first coefficient of 10 denotes the change in blood pressure for a dose of 10 mg, the second coefficient of 2, the change for each additional dose of 10 mg, the third coefficient of 3, the change for each additional dose of 20 mg, and the fourth coefficient, the change for each additional dose of 30 mg.

For instance, if the patient received a dose of 40 mg, the equation would be 10 + 2(20) + 3(30), resulting in a 140 mmHg change in blood pressure. The calculation would be 10 + 2(20) + 3(30) + 4(10) if the patient received a 50 mg dose, which would result in a 190 mmHg change in blood pressure.

As a result, we can infer from the linear model that a 100 mg dose of the experimental medication would result in a 540 mmHg change in the patient's blood pressure.

At Kennedy High School, the probability of a student playing in the band is 0. 15. The probability of a student playing in the band and playing on the football team is 0. 3. Given that a student at Kennedy plays in the band, what is the probability that they play on the football team?

Answers

The probability that a student at Kennedy High School plays on the football team given that they already play in the band is 2/1 or simply 2.

To solve this problem, we can use conditional probability. We want to find the probability that a student plays on the football team given that they already play in the band.

Let's use the formula for conditional probability:

P(Football | Band) = P(Football and Band) / P(Band)

We know that P(Band) = 0.15, and P(Football and Band) = 0.3.

So,

P(Football | Band) = 0.3 / 0.15

Simplifying, we get:

P(Football | Band) = 2

Therefore, the probability that a student at Kennedy High School plays on the football team given that they already play in the band is 2/1 or simply 2.

Note: This answer may seem unusual because probabilities are typically expressed as fractions or decimals between 0 and 1. However, in this case, we can interpret the result as saying that students who play in the band are twice as likely to also play on the football team compared to the overall population of students.

Using Newton's Method, estimate the positive solution to the following equation by calculating x2 and using X0 = 1. x⁴ – x = 3 Round to four decimal places.

Answers

Answer:

To estimate the positive solution to the equation x⁴ – x = 3 using Newton's Method, we can start by taking the derivative of the equation, which is 4x³ - 1. Then we can use the formula X1 = X0 - f(X0) / f'(X0), where X0 = 1, f(X0) = 1⁴ - 1 - 3 = -3, and f'(X0) = 4(1)³ - 1 = 3. Plugging these values into the formula, we get:

X1 = 1 - (-3) / 3

X1 = 2

Now we can repeat the process using X1 as our new X0:

X2 = X1 - f(X1) / f'(X1)

X2 = 2 - (2⁴ - 2 - 3) / (4(2)³ - 1)

X2 ≈ 1.7708

Therefore, the positive solution to the equation x⁴ – x = 3, rounded to four decimal places, is approximately 1.7708.

Step-by-step explanation:

The positive solution to the equation x⁴ – x = 3, estimated using Newton's Method with x₀ = 1 and x₂ as the final estimate, is approximately 1.5329, rounded to four decimal places.

To use Newton's Method to estimate the positive solution to the equation x⁴ – x = 3, we need to find the derivative of the function f(x) = x⁴ – x. This is given by:

f'(x) = 4x³ - 1

We can then use the formula for Newton's Method:

x(n+1) = x(n) - f(x(n)) / f'(x(n))

where x(n) is the nth estimate of the solution.

Starting with x₀ = 1, we can plug this into the formula to get:

x₁ = 1 - (1^4 - 1 - 3) / (4(1^3) - 1) ≈ 1.75

We can then repeat this process using x₁ as the new estimate, to get:

x₂ = 1.75 - (1.75^4 - 1.75 - 3) / (4(1.75^3) - 1) ≈ 1.5329

- 2. Find all values of x where f '(x) = 0 for f(x) = arcsin(e2x – 2x).

Answers

The only value of x where f'(x) = 0 is x = 0.

Let's find all values of x where the derivative of f(x) = [tex]arcsin(e^(2x) – 2x)[/tex] is equal to 0.

Step 1: Find the derivative f'(x) using the chain rule.

For this, we'll need to differentiate [tex]arcsin(u)[/tex] with respect to u, which is [tex](1/√(1-u^2))[/tex], and then multiply by the derivative of u [tex](e^(2x) – 2x)[/tex]with respect to x. So, f'(x) = [tex](1/√(1-(e^(2x) – 2x)^2)) * d(e^(2x) – 2x)/dx[/tex]

Step 2: Find the derivative of e^(2x) – 2x with respect to x. Using the chain rule and the derivative of [tex]e^u: d(e^(2x) – 2x)/dx = 2e^(2x) – 2[/tex]

Step 3: Combine the derivatives. f'(x) =[tex](1/√(1-(e^(2x) – 2x)^2)) * (2e^(2x) – 2)[/tex]

Step 4: Set f'(x) equal to 0 and solve for x. [tex](1/√(1-(e^(2x) – 2x)^2)) * (2e^(2x) – 2) = 0[/tex]

Since the first part of the product [tex](1/√(1-(e^(2x) – 2x)^2))[/tex] is never 0, we can focus on the second part: [tex]2e^(2x) – 2 = 0[/tex]

Step 5: Solve for x. [tex]2e^(2x) = 2 e^(2x) = 1[/tex]

The only way this is true is when 2x = 0, since [tex]e^0 = 1: 2x = 0 x = 0[/tex]

So, the only value of x where f'(x) = 0 is x = 0.

label each scatterplot correctly,
no association
linear negative association linear positive association
nonlinear association

Answers

Without a specific set of scatterplots to examine, I can provide some general guidelines for labeling scatterplots based on their association:

1. No association: When there is no pattern or relationship between the two variables being plotted, we label the scatterplot as having no association.

2. Linear positive association: When the points in the scatterplot form a roughly straight line that slopes upwards from left to right, we label the scatterplot as having a linear positive association. This means that as the value of one variable increases, the value of the other variable also tends to increase.

3. Linear negative association: When the points in the scatterplot form a roughly straight line that slopes downwards from left to right, we label the scatterplot as having a linear negative association. This means that as the value of one variable increases, the value of the other variable tends to decrease.

4. Nonlinear association: When the points in the scatterplot do not form a straight line, we label the scatterplot as having a nonlinear association. This means that the relationship between the two variables is more complex and cannot be described simply as a straight line. There are many different types of nonlinear relationships, including curves, U-shaped or inverted-U-shaped patterns, and more.

Determine whether the given points represent the vertices of a trapezoid If so, determine whether it is isoscoles or not

A(-4,-1),B((-4,6),C(2,6),D(2,-4)

Answers

Answer:

It is a trapezoid

Step-by-step explanation:

Yes, the given points represent the vertices of a trapezoid.

A trapezoid is a quadrilateral with one set of parallel sides. In this case, the parallel sides are AB and CD. The other two sides, AD and BC, are not parallel.

The trapezoid is not isosceles because the two non-parallel sides are not congruent. AD has a length of 6 units, while BC has a length of 4 units.

Here is a diagram of the trapezoid:

A(-4,-1)

B((-4,6)

C(2,6)

D(2,-4)

A trapezoid is a quadrilateral with at least one pair of parallel sides. In this case, sides AB and CD are parallel because they have the same slope. So, the given points do represent the vertices of a trapezoid.

An isosceles trapezoid has two congruent legs (non-parallel sides). In this case, the length of side AD is `sqrt((-4-2)^2+(-1+4)^2)=sqrt(36+9)=sqrt(45)` and the length of side BC is `sqrt((-4-2)^2+(6-6)^2)=sqrt(36+0)=sqrt(36)`. Since `sqrt(45)` is not equal to `sqrt(36)`, the trapezoid is not isosceles.

If 10 monkeys vary inversely when there are 18 clowns. How many monkeys will there be with 4 clowns? Your final answer should be rounded to a whole number with no words included

Answers

The number of monkeys when number of monkeys varies inversely to the number of clowns is 45.  

What is inverse proportion:

Inverse proportion is a mathematical relationship between two variables, in which an increase in one variable causes a proportional decrease in the other variable, and a decrease in one variable causes a proportional increase in the other variable.

In other words, the two variables vary in such a way that their product remains constant.

Here we have

10 monkeys vary inversely when there are 18 clowns.

We can set up the inverse variation equation as:

=> monkey ∝ 1/clown

If k is the constant of proportionality.

=> Monkey (clown) = k

It is given that when there are 10 monkeys, there are 18 clowns, so we can write:

=> (10)(18) = k

Solving for k, we get:

k = (10 x 18) = 180

Now we can use this value of k to find the number of monkeys when there are 4 clowns:

=> monkey = k/clown = 180/4 = 45

Therefore,

The number of monkeys when number of monkeys varies inversely to the number of clowns is 45.

Find the slope of the line represented below

Answers

The slope of the line that is represented by the given data in the question is 3/4.

To find the slope of a line, we need to use the formula:

slope = (change in y) / (change in x)

We can choose any two points on the line and use their coordinates to calculate the change in y and the change in x. Let's choose the points (-9, 4) and (7, 16) from the given data.

Change in y = 16 - 4 = 12

Change in x = 7 - (-9) = 16

Plugging these values into the slope formula, we get:

slope = 12 / 16 = 3 / 4

We can also interpret this slope as the rate of change of y with respect to x. For every increase of 1 in x, y increases by 3/4. Similarly, for every decrease of 1 in x, y decreases by 3/4.
