Consider a circle whose size can vary. let r represent the radius of the circle (in cm) and let c represent the circumference of the circle (in cm). suppose the function g determines the radius of the circle in cm, r , given its circumference in cm, c . write a function formula for g . g ( c ) = what does g ( 15 ) represent in this context? select all that apply. the circumference (in cm) of a circle whose radius is 15 cm. the radius (in cm) of a circle whose circumference is 15 cm. a circle with a circumference of 15 cm. a circle with a radius of 15 cm. if g ( a ) = 15 , what does a represent in this context? select all that apply. the circumference (in cm) of a circle whose radius is 15 cm. a circle with a circumference of 15 cm. a circle with a radius of 15 cm. the radius (in cm) of a circle whose circumference is 15 cm.

represents the radius (in cm) of a circle whose circumference is 15 cm

if , then a represents the circumference (in cm) of a circle whose radius is 15cm

Step-by-step explanation:

In a circle the following relationship can be posed:

Let g be a function that determines the radius of the circle from the value of its circumference, so, you have:

Thus, represents the radius (in cm) of a circle whose circumference is 15 cm. You have to .

On the other hand, if , then represents the circumference (in cm) of a circle whose radius is 15cm. You have to

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

answer: your correct answer is b. d.
