Find the domain of f(x) = squareroot x^2 - 36

x is greater than or equal to 6 or

x is less than or equal to -6

Step-by-step explanation:

f(x)= sqrt x^2-36

Plug in 6. for x

Results are sqrt (6)^2-36= sqrt 0 = 0

Plug in -6 for x

Results are (-6)^2-36= sqrt 36-36 = sqrt 0 = 0

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
