Suppose and exponential function is to fit to a set of data. which of the following residual plots indicates that this function was an appropriate fit for the data?

Suppose and exponential function is to fit to a set of data. Which of the following residual plots indicates that this function was an appropriate fit for the data?
The appropriate fit for an exponential data is given by D.

This is because it shows the perfect exponential fit for the residuals. 

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
