Steve cut a circular piece of mirror glass with the diameter of 20 cm in order to make a frame for it he needed to calculate the circumference what is the circumference and centimeters of the piece of the mirrored glass

The circumference is 62.8 cm.

Step-by-step explanation:

To find the circumference, use 3.14 * 20 = 62.8

(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.
