FALSE

The distributive property comes in handy when we see an expression such as the following: 5(x + 3). This is because the 5 needs to be distributed to both the x and the 3.

For the given expression, combining like terms would be the next step because 2y and 6y can be added together.

Hope this helps!

Answer:

The length of the ladder is about 34.1 feet.

Step-by-step explanation:

cos(62°) = 16/h

h cos(62°) = 16

h = 16/cos(62°) = 34.1 feet

The 140% of the number 25 will be equal to 35. We will calculate it by the concept of percentage.

The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.

Here we need to find out 140% of what number is 35

Suppose that number is x so the equation will be

[tex]140\%\times x=35\\\\\\\dfrac{140}{100}\times x=35\\\\\\x=\dfrac{35\times 100}{140}\\\\\\x=25[/tex]

Hence % of the number 25 will be equal to 35. We will calculate it by the concept of percentage.

Answer:

(x+4)² + (y+9)² = 100

Step-by-step explanation:

We want to find the equation of a circle with a radius of length 10 and a center at (-4, -9).

general equation of circle : (x-h)² + (y-k)² = r²

where (h,k) is at center and r = radius

the center is at (-4,-9) so h = -4 and k = -9 and the circle has a radius of 10 so r = 10

so we have (x-h)² + (y-k)² = r²

h = -4 , k = -9  and r = 10

(x-(-4))² + (y-(-9))² = 10²

==> apply double negative sign rule and remove parenthesis for -(-4) and -(-9)

(x+4)² + (y+9)² = 10²

==> simplify exponent

(x+4)² + (y+9)² = 100

and we are done!

Answer:

Option D

Step-by-step explanation:

Given:

∴ x coordinate of center point: (h, k) ⇒ (-4, -9)

∴ y coordinate of center point: (h, k) ⇒ (-4, -9)

Equation of circle formula:

Substitute the radius in the formula;

Substitute the x and y coordinate in the formula;

Therefore, Option D is correct.

the probability that the light bulb will still be working after 1000 hours of use is 0.93 (or 93%).

To find the probability that the light bulb will still be working after 1000 hours of use, we can use the fact that the sum of the probabilities of all possible outcomes must be equal to 1.

Given that the probability of the light bulb failing after 1000 hours of use is 0.07, the probability of it still working after 1000 hours is:

Probability of the light bulb working after 1000 hours = 1 - Probability of the light bulb failing after 1000 hours

Probability of the light bulb working after 1000 hours = 1 - 0.07

Probability of the light bulb working after 1000 hours = 0.93

So, the probability that the light bulb will still be working after 1000 hours of use is 0.93 (or 93%).

Answer:

The domain is all real numbers, x, such that x ≤ 4/3.

The range is all real numbers, y, such that y ≥ 0.

Step-by-step explanation:

The domain is the set of values that can be substituted for x.

The expression inside the square root cannot be negative; therefore, it must be zero or positive.

4 - 3x ≥ 0

-3x ≥ -4

x ≤ 4/3

The domain is: x ≤ 4/3

The range is the set of value that can be substituted for y.

When all numbers of the domain are used for x, and then the square root is taken, the smallest value that the square root can have is zero. Therefore, y can be all real numbers greater than or equal to 0.

The range is: y ≥ 0

Answer:

x = 62

Step-by-step explanation:

the angle between a tangent and the radius at the point of contact = 90°

then Δ PTO is right

the sum of the 3 angles in the triangle = 180° , so

x = 180 - 90 - 28 = 180 - 118 = 62

Answer:

Step-by-step explanation:

TP is a tangent to the circle at centre O

means

TP is perpendicular to TO

Then

m∠OTP = 90°

Then

OTP is a right triangle

Then

x = 90 - 28

  = 62

The quotient of (x⁴ + 5x³ – 3x – 15) and (x³ – 3) is a polynomial f(x) = x⁷ + 5x⁶ - 6x⁴ - 30x³ + 9x + 45

An equation is an expression that shows the relationship between two or more variables and numbers.

The quotient of (x⁴ + 5x³ – 3x – 15) and (x³ – 3) is a polynomial. Let f(x) represent the polynomial, hence:

f(x) = (x⁴ + 5x³ – 3x – 15)(x³ – 3)

f(x) = x⁷ + 5x⁶ - 3x⁴ - 15x³ - 3x⁴ - 15x³ + 9x + 45

f(x) = x⁷ + 5x⁶ - 6x⁴ - 30x³ + 9x + 45

Explanation:

Pick any term and subtract off the previous one to get the common difference.

For instance, let's say we picked 11

11-6 = 5

Or we could pick 6

6-1 = 5

Each time we get 5 as the common difference. It says that to get each next term, we add on 5.

The part of the function j(x) which shows the graph opens downward is the coefficient of x². Depending on whether the value is positive or negative, we will understand if it opens upward or downward.

Answer:

x²-16

Step-by-step explanation:

x²-16 =0

Add 16 to both sides

x²= 16

For x²=(fa) the solutions are x = √(fa), -√(fa)

X=√16 ,X= -√16

√16=4

-√16 = -4

x=4, x= -4

The value of C is 0.03030 if the f(x, y) = c(x 2y), x = 1, 2 and y =1, 2, 3  because the sum of the probability is always 1

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

f(x, y) = c(x+2y),

x = 1, 2 and y =1, 2, 3

f(1, 1) = C(1 + 2)  = 3C

f(1, 2) = C(1 + 4)  = 5C

f(1, 3) = C(1 + 6)  = 7C

f(2, 1) = C(2 + 2)  = 4C

f(2, 2) = C(2+ 4)  = 6C

f(2, 3) = C(2 + 6)  = 8C

We know the sum of the all probability is 1

3C+5C+7C+4C+6C+8C=1

33C =1

C = 0.03030

Thus, the value of C is 0.03030 if the f(x, y) = c(x 2y), x = 1, 2 and y =1, 2, 3  because the sum of the probability is always 1

The average of a data set is the number "in the middle" of all of the numbers. This is a measurement of the center of a data set. Another word for average is mean.

How to Calculate the Average

The average or mean is calculated by adding all of the values together. Then, divide this sum by the number of data points. For example, if the sum of 5 different data points is 10, then the average would be 10/5.

Finding the Average

Now, let's find the average of this specific data set. First, add all of the data together.

Then, count the number of terms. There are 7 different terms within this data set. So, next divide the sum by the number of terms.

This means that the average of the set is 40.

Other Measurements of Center

The mean is not the only measurement of center. There are 3 common measures of center.

Answer:

Step-by-step explanation:

If the frequency of the sound wave is 2π/3, then the time period of the sound wave will be 0.447 seconds. Then the amplitude is 14.

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.

A sound wave is modeled with the equation y = 14 cos (2π/3) θ.

The frequency of the sound wave will be

[tex]f = \dfrac{2\pi}{3}[/tex]

Then the time period will be

[tex]T = \dfrac{1}{f}\\\\T = \dfrac{1}{2\pi /3}\\\\T = \dfrac{3}{2\pi}\\\\T = 0.477 \ \rm seconds[/tex]

Then the amplitude of the sound wave will be

A = 14
