Determine the average rate of change from 0 to 3.

A

Step-by-step explanation:

The average rate of change of f(x) in the close interval [ a, b ] is

Here [ a, b ] = [ 0, 3 ]

From the graph

f(b) = f(3) = 4

f(a) = f(0) = - 3 , thus

average rate of change = = → A

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
