What is the measure of the radius of m?

The radius of circle is 10.5 units

D is correct

Step-by-step explanation:

We are given a circle with centre M

We need to find the radius of circle.

Radius: It is distance from centre to a point on circle.

In figure,

Center at M

Points on circle, R and S

Radius should be RM, SM

From figure,

RM=10.5 units

SM=10.5 units

RM=SM=10.5 units

Hence, The radius of circle is 10.5 units

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

greater than one
