Find the length of the radius of the following circle. (x + 2)2 + y2 = 10 5 √(10) 100

For this case we have the following equation:

 (x + 2) 2 + y2 = 10

 We must remember that the standard equation of the circle is given by:

 (x - h) 2 + (y - k) 2 = r2

 Where r is the radius.

 Therefore, in the given equation the radius is:

 r ^ 2 = 10

 Clearing we have:

 R = root (10)

 The length of the radius of the circle is:

 √ (10)

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

well the answer to that is xoxoxo
