Answer: 800 feet²
Step-by-step explanation:
Lets remove the brackets from the function's expression
A(x) = -2x²+80x
So we got the quadratic function and we have to find the x that corresponds to function's maximum. Let it be X max
As we know Xmax= (X1+X2)/2 , where X1 and X2 are the roots of the function A(x)
Lets find X1 and X2
x(80-2x)=0
x1=0 80-2*X2=0
x2=40
So Xmax= (0+40)/2=20
So Amax= A(20)= 20*(80-2*20)=20*40=800 feet²
Answer:
a. 64, 128, 256 (geometric)
b. 11, 13, 15 (arithmetic)
c. 53, 61, 69 (arithmetic)
Step-by-step explanation:
(a) Each term is twice the previous term. so it is geometric with a common ratio of 2
(b) The difference between each term is 2. So it is arithmetic with a common difference of 2
(c) The difference between each term is 8. So it is arithmetic with a common difference of 8

Answer:
Step-by-step explanation:
b = pints of blueberries
c = pints of cherry tomatoes
3b + 2c = 28
2b = c
First, substitute 2b into the c of the first equation.
3b + 2(2b) = 28
3b + 4b = 28
7b = 28
b = 4
Then, substitute 4 into the b of the second equation.
2(4) = c
c = 8
Then, substitute both values into the first equation to check.
3(4) + 2(8) = 28
12 + 16 = 28
