Answer:

B and D

Step-by-step explanation:

square root means something times itself equals the number in the square root symbol so you go down the list and times everything by its self like this

-32 * -32 = 1024

8 * 8 = 64

32 * 32 = 1024

-8 * -8= 64

Answer:

Step-by-step explanation:

The question is faulty. It works once it gets to + 1, +2, +3

The other x values should be 0 and - 1 instead of -1 and -3.

Here's the formula I get.

f(x) = 2*3^(2x + 1)

f(0) = 2*3^(1)

f(0)= 6

f(-1) = 2*3^(-2 + 1)

f(-1) = 2*3^(-1)

f(-1) = 2/3

f(-2) = 2*3^(-2*2 + 1)

f(-2) = 2*3^(-4 +1)

f(-2) = 2*3^(-3)

f(-2) = 2/27

Since my answers do not agree with the given answers, I can do nothing more to help you. I will pass this along to someone I know who will see through it.

Mandarinka [93]

Answer:

24 trees per acre

Step-by-step explanation:

Let x be the optimal tree density per acre and y be the number of bushels yield per tree

Since for each unit change of x from 28 trees/acre, we have 2 unit change of y from 40 bushels per tree in the reversed direction

Change of x from 28 is x - 28

Change of y from 40 is y - 40
