A football team plays in a large stadium. With a ticket price of $15, the average attendance at recent games has been 20,000. A market survey indicates that for each $1 increase in the ticket price, attendance decreases by 400 people. Express the revenue from a baseball game, R, as a function of the ticket price, x.

Answer:

R(x) = (20,000 - 400x)(15+x)

Step-by-step explanation:

Given,

The original price of each ticket = $ 15,

Original number of people or attendance = 20,000

Let the price of each ticket is increased by x times of $ 1,

That is, new price of each ticket = ( 15 + x ) dollars,

∵ for each $1 increase in the ticket price, attendance decreases by 400 people,

So, the new number of people = 20,000 - 400x

Since,

Revenue = number of people × price of each ticket

⇒ R(x) = (20,000 - 400x)(15+x)

Which is the required function.

If a point is on the perpendicular bisector of a segment, then it is: A. the midpoint of the segment.

B. equidistant from the endpoints of the segment.

C. equidistant from the midpoint and one endpoint of the segment.

D. on the segment.

The bisector passes through the midpoint, then any point on the bisector is equidistant to both endpoints. Therefore, the correct answer is B.

What is Bisector?A bisector is something that cuts an object into two equal parts. It is applied to angles and line segments. In verb form, we say that it bisects the other object.

To create a perpendicular bisector of a segment, it is a line drawn through the midpoint of the segment. Although one would immediately think that (A) would be the answer, just because a point is found on the perpendicular bisector, doesn't mean that it is immediately the midpoint. Although the midpoint is definitely found on the segment, there are numerous other points found on the segment. The midpoint is a point equidistant to both endpoints. Since the bisector passes through the midpoint, then any point on the bisector is equidistant to both endpoints.

Hence, The bisector passes through the midpoint, then any point on the bisector is equidistant to both endpoints.

In a group of 120 seventh graders. 30% have completed their science project. How many students have completed their science project.

Answer: 36

Step-by-step explanation:

120 students is the same as 100%, so you would divide 120 by 100 and your quotient would be 1.2 Then you multiply 30 by 1.2, since you would multiply 100 by 1.2 to get 120. 30×1.2=36. So 36 seventh graders have completed their science project.

A landscaper charges customers a one time fee and an hourly rate of $25. For 3 hours of work, it charges $95 - I need the identity point in the scenario

- Write the equation in point-slope form

- write the equation in slope-intercept form

- Write the equation in standard form

Answer:

C = 20 + 25h ..... Required identity

(C - 20) = 25(h - 0) ..... Point-slope form

C = 25h + 20 ..... Slope-intercept form.

25h - C = - 20 .... Standard form.

Step-by-step explanation:

A landscaper charges customers a one time fee and an hourly rate of $25.

If for 3 hours of work, it charges $95.

Then, C = C' + 25h ......... (1)

Where C is the total charge, C' is the fixed charge and h is the number of hours he works.

Therefore, putting C = $95 and h = 3, we get from equation (1),

95 = C' + 75

⇒ C' = 20

Therefore, the equation (1) becomes C = 20 + 25h

Hence, this is the identity in the scenario. (Answer)

Now, the point-slope form of the equation is (C - 20) = 25(h - 0)

where slope is 25 and the point is (0,20).

Now, C = 25h + 20

is the slope-intercept form having slope 25 and y-intercept 20.

Now, the standard form of the equation is 25h - C = - 20 (Answer)

Since January 1, 1960, the population of Slim Chance has been described by the formula P=33000(0.98)^t where P is the population of the city t years after the start of 1960. At what rate was the population changing on January 1, 1978?

If January 1, 1960, the population of Slim Chance has been described by the formula P=33000(0.98)^t where P is the population of the city t years after the start of 1960. The rate that the population change on January 1, 1978 is : 22,940

Let P=33000(0.98)^t

Let t = 18 (1978-1960)

Now let determine at what rate was the population changing on January 1, 1978

Change in population = 33000(0.98)^18

Change in population= 22,939.47

Change in population=22,940 (Approximately)

Inconclusion if January 1, 1960, the population of Slim Chance has been described by the formula P=33000(0.98)^t where P is the population of the city t years after the start of 1960. The rate that the population change on January 1, 1978 is : 22,940

Let

P-------> the population of Slim Chance (Since January 1, 1960)

t--------> the number of years (after the start of 1960)

we know that

Step 1

Take the derivative of P with respect to t

Step 2

Evaluate the derivative of P with respect to t for

substitute

therefore

the answer is

The rate of change is
