Line segment YZ is a tangent to circle X , and X is the center of the circle. What is the length of the radius of the circle?
A.12.8
B.12
C.6
D.4

C. 6

Step-by-step explanation:

8^2+r^2=10^2

64+r^2=100

r^2=36

Therefore, r=6

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
