Answer:
$14
Step-by-step explanation:
The revenue from sales of fans is the product of the number of fans sold and the price at which they are sold:
R(p) = n·p = (1960-70p)p
R(p) = 70(28 -p)p
This equation describes a parabola that opens downward and has zeros at p=0 and p=28. The axis of symmetry is halfway between those zeros, at p=14. It goes through the vertex or point of maximum revenue.
The price for maximum revenue is p = 14 dollars.
Answer:
Angles 7 and 8 are supplementary because they are a pair of adjacent angles that form a straight line.
Supplementary angles add up to 180°
If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).
Hey there!
You can find your rate of change by using the slope formula:

You can use the first two points you've been given, starting with the least. These two points are (0, 0) and (1, 35). Just plug these into your formula and solve.




35 will be your answer.
Hope this helped you out! :-)
