Please help me with my algebra.

Answer:

2. an integer > 0

Step-by-step explanation:

At an ice cream shop, the profit, P(c), is modeled by the function ;

P(c) = 0.87c. An appropriate domain for this function is an integer [tex]\geq[/tex] 0.

A function is defined as a relation between the set of inputs having exactly one output each.

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

At an ice cream shop, the profit, P(c), is modeled by the function ;

P(c) = 0.87c,

where c represents the number of ice cream cones sold.

An appropriate domain for this function is an integer [tex]\geq[/tex] 0.

Step-by-step explanation:

The only people who were contacted were those with a landline, which is not the entire U.S. Because of the cell phone, there are many in the U.S. who do not own a landline, so this does not represent the entire U.S. population.

It will take almost 6 years to depreciate the value of the car to 10100 dollars.

Depreciation is a term used to indicate the decreasing value of an asset over time due to use, unfavorable market conditions and so on.

Initial amount of the car = 15700 dollars

Depreciating percent = 7.5% = 7.5/100 = 0.075

Final amount = 10100 dollars

Number of years taken to depreciate the value of the car to 10100 dollars can be found by the formula,

A = P(1 + r)ⁿ

where A = 10100 dollars, P = 15700 dollars, r = -0.075.

10100 = 15700 (1 - 0.075)ⁿ

10100 / 15700 = (1 - 0.075)ⁿ

0.6433 = (0.925)ⁿ

Taking logarithm on both sides,

㏒ 0.6433 = ㏒ (0.925)ⁿ

We have the power rule for logarithms, ㏒ (mⁿ) = n ㏒(m)

㏒ 0.6433 = n ㏒ (0.925)

n = ㏒ 0.6433 / ㏒ (0.925)

n = 5.658 ≈ 6 years

Hence almost 6 years will be taken to depreciate the value of the car to 10100 dollars.

Answer:

πr2

Step-by-step explanation:

The shape changed, but the amount of space inside the shape remained the same. The space inside the parallelogram is the same as the space, or area, inside the circle. The area of the circle is 0.5 × circumference × radius = πr2.

Answer:

Area = 36 sq. units

Step-by-step explanation:

The 3 values you need to solve for the area are the top base length, bottom base length, and height.

Top base length = 7 . It's the distance between point A and B.

Bottom base length = 11. It's the distance between points C and D.

Height = 4. It's the perpendicular distance from the top to the bottom base.

The formula to solve the area of a trapezoid (or trapezium, I'm American) is:

A = [tex]\frac{1}{2}h(b_{1} +b_{2})[/tex]

Put in the numbers above for the unknowns and you will get this:

A = [tex]\frac{1}{2}(4)(7 + 11)[/tex]

Simplify:

A= [tex]\frac{1}{2}(4)(18)[/tex]

A = 2(18)

A = 36

So the answer is 36. Hope I helped!

Answer:

36

Step-by-step explanation:

top base= B(x)-A(x)= 10-3= 7

bottom base= C(x)- D(x)= 12-1= 11

height= A(y) - D(y) = B(y)- C(y)= 5-1=4

Area= 1/2(7+11)*4= 36

You have to use the subsitution method

Step-by-step explanation:

so it's telling you what the y value is an you have to subsitute 6x-b where the y is.

so the new eqaution would be -3x+1/2(6x-b)=-3

-3x+3x-b=-3

-b=-3

b=3

Answer:

1774.67π mm³

Step-by-step explanation:

Please find attached to this question, the required diagram.

From the question, we are told we have a spherical mold.

We would find the volume of a spherical mold using the formula for the volume of a sphere.

The volume of a sphere is calculated as : 4/3πr³

From the attached diagram, we are given the Diameter do the spherical mold as: 22mm

Radius of the spherical mold = Diameter ÷ 2 = 22mm÷ 2 = 11mm

The volume of the spherical mold = 4/3 × π × 11³

= 1774.6666667π mm³

Approximately and leaving it in terms of pi (π)= 1774.67π mm³

Step-by-step explanation:

Measure of spread is used in describing the variability in a sample.

Examples of measure of spread are: Mean, Median and Mode.

A measure of spread helps in giving an idea of how well the mean, or mode, or median, whichever of the three measure of spreads we use, represents the data under consideration. If the spread of values in the data set is large, that means there a lot of variation between the values of the data set. It is always better to have a small spread.

Answer:

Measuring the spread of a data set tells us how far are the values of data set to respect the mean. For example, large mean absolute deviation (MAD) value indicates that the values of data set are very different from the mean, i. e., they are very spread. Therefore, the mean is not representative of the data. On the other hand, in a small spread case, the mean is representative.

Answer:

x = 34

Step-by-step explanation:

The 3 labeled angles create a straight line, so that means they will add up to 180°.

(x + 12) + 100 + x = 180

2x + 112 = 180

Subtract 112 from both sides.

2x = 68

Divide both sides by 2.

x = 34

The value of x in the figure is, 34.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

We know that;

A straight line make an angle 180°.

Hence, By the figure we get;

⇒ (x + 12)° + 100° + x° = 180°

⇒ x + 12 + 100 + x = 180

⇒ 2x + 112 = 180

⇒ 2x = 180 - 112

⇒ 2x = 68

⇒ x = 34

Answer:

D.) not enough information given

Step-by-step explanation:

It is 100% correct on Edgeunity June 2020

Option A.  yes by ASA is correct.

Triangles F H G and K J G share common point G. The lengths of sides H G and G J are congruent. Angles F H G and K J G are right angles.

Similar triangles, are those triangles which have similar properties,i.e. angles and proportionality of sides.

Since we have one angle FHG and angle KJG and one side from both triangle HG = GJ equal
so the angle opposite to equal side must be equal. i.e.
Angle HFG = Angle JKG
hence , triangle is congruent by ASA

Thus, Option A.  yes by ASA is correct.
