Answer:
maximum area will be 1058 square yards
maximum height will be 81 feet
Step-by-step explanation:
P = 2L +2W
but in this case it will be P= L+2W and P=92 yards
L+2W = 92
Solve for L , L = 92-2W
The area of rectangle A = L x W
Plug in L and simplify: A = (92-2W)W =92W -2W²
Plot in your calculator and look for maximum so when the width is 23 yards maximum area will be 1058 square yards.
Second problems is the maximum height of the rocket. Maximum will be at the vertex of the upside-down parabola.
I think that is D cus you take 10 off
The average speed is 4 miles per minute
WORK:
8mi=2minutes
÷2 ÷2
------------
4 1
4mi=1 minute
(To any other people, please correct me if I'm wrong) I believe that the answer would be at the rate of 24.4 miles per gallon
Divide each term in the numerator by 2y:-
= -31y^2 + 5y + 16 is the answer.
