Which of the following relations are functions? {(0,1), (0,2), (5,2), (-5,2), (5,7)}
O {(-3,2), (-2,2), (1,2), (-3,1), (0,3)}
{(-1,6), (-2,8), (-1,2), (-5,1), (0,6)}
{(-2, 6), (2,0), (3,6), (4.-1), (5. 3)}

answer: 2/4

step-by-step explanation:

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

y=sec x is the correct answer
