Suppose a chord is 20 inches
long and is 24 inches from the
center of the circle. find the
length of the radius.

r=26

Step-by-step explanation:

20/2=10

a^2+b^2=c^2

a=10

b=24

c=?

100+576=676

=r

r=26

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
