The product of -5 and 12 is -60
Given:
The yield of strawberries per acre is
S = -(w - 2)² + 50
where
S = number of pints of strawberries per acre
w = acre-feet of water
Strawberries sell for $3 per pint
Water costs $5 per acre-feet.
The yield function is the revenue minus the expenses. It is
Y = (S pints)*($3 per pint) - (w acre-ft)*($5 per acre-ft)
Y = -3(w - 2)² -5w + 150 dollars
A graph of the yield function is shown below.
It indicates that
a) the yield is maximum when the acre-feet is about 1.5;
b) the yield increases between zero and 1.5 acre-feet;
c) the yield decreases quickly when the acre-feet exceed 1.5;
d) the yield vanishes when the acre-feet exceed 8.
Answer: 318
Step-by-step explanation:
7 to the 3rd power is 343, 343 minus 25 is 318
There are a total of 20 hamsters. I solved it by dividing the 8 hamster by 2 to get what 1/5 would be. After i know 1/5=4 hamsters i multiplied 4*5
4 hamsters is the same as 1/4 of all the hamster
8 hamsters=2/5
12 hamster=3/5
16 hamster=4/5
I believe the answer is c
