The area of a rectangular garden in square feet can be represented by <? - 10x + 21. The length is 2 - 7 feet. You have been hired to fertilize the garden. Recall that the area of the garden is 22 - 10x + 21. If 3 = 20 and the fertilizer costs $0.27 per square foot, how much will it cost to fertilize
the garden?

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
