Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of
increase or decrease.
y = 42(0.913)

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

20

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

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
