The cost of the piece of granite is $137.70. What would you expect to pay for a similar piece of granite that is 108 inches by 60 inches?

2203.20

Step-by-step explanation:

The first piece is 15 by 27 = 405 sq in. (as shown in the pic someone else posted.)

$137.70 / 405 = 34 cents per sq in\

A piece that is 108 by 60 = 6480 sq in

6480 x .34 = $2,203.20

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
