Clair has250 pennies some pennies are in a box the rest are in her bankthere are more then 100 pennies in each place how many pe
9966 [12]

Answer:

In each place there must be more 100 pennies, but as the total 250 pennies, there are several ways that the money is distributed.

Because there may be 101 pennies in the box and 149 pennies in the bank, but it can also be the opposite; in the box 149 pennies and in the bank 101 pennies.

Therefore, there are many options to answer the question, as long as it is met that there are more than 100 pennies in one place.

Total profit P is the difference between total revenue R and total cost C. Given the following​ total-revenue and​ total-cost fu
gavmur [86]

Answer:

The profit function is:

P(x)=-x^2+1280x-3300

The maximum value is 406, 300 occurring when x = 640.

Step-by-step explanation:

The revenue function is:

R(x)=1300x-x^2

And the cost function is:

C(x)=3300+20x

Then the total profit function will be:

P(x)=R(x)-C(x)=(1300x-x^2)-(3300+20x)=-x^2+1280x-3300

This is a quadratic function.

Therefore, the maximum value of the total profit will occur at its vertex point.

The vertex of a quadratic is given by:

\displaystyle \Big(-\frac{b}{2a}, f\Big(-\frac{b}{2a}\Big)\Big)

In this case, a = -1, b = 1280, and c = -3300.

Then the point at which the maximum profit occurs is at:

\displaystyle x=-\frac{1280}{2(-1)}=640

And the maximum profit will be:

P(640)=-(640)^2+1280(640)-3300=406300

nika2105 [10]
This would mean that she has been in school for about 1,000 days. Thus, we need to figure out the amount of days she would have went to school within the week. This would normally be 5 days within the 7. 

5/100 x 1000 is 714.28

When rounded to the nearest ten, it would end up at 710.
