Answer:
Step-by-step explanation:
start by foiling out the given function
next, use the power rule to find the derivative
power rule: To use the power rule, multiply the variable's exponent n, by its coefficient a, then subtract 1 from the exponent. If there's no coefficient (the coefficient is 1), then the exponent will become the new coefficient.
=-30
-2*-3=6
-1*5=-5
6 x -5=-30
86 feet
Assuming the court is rectangular in shape then
area = length × width
length = area / width = = 86 feet
I don't know but I think it is B) The slope is negative, and a linear model is a good fit for the data.
