Use the equation f(x) = 0.01x2 + =

A about 3,000 ft

X+0.2 to estimate what radius Zachary would need to irrigate 250.000 bushels of com

B. about 4 875 ft

C. about 3,967 ft

D. about 5,000 ft

D. about 5,000 ft

Step-by-step explanation:

Given the equation:

We want to estimate what radius Zachary would need to irrigate 250,000 bushels of corn.

Substituting f(x)=5000, we have

Using the quadratic formula

The correct option is D

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
