A sector has an area of 50 ft sq, and a central angle of 45 degrees. Find the radius.

Step-by-step explanation:

45° is 1/8 of a circle, so the area of the sector is 1/8 the area of the circle.

Area of circle = 8*50 = 400 sq ft

πr² = 400

r = √(400/π) = 20/√π ≈ 11.3 ft

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
