Aball is thrown from an initial height of 3 feet with an initial upward velocity of 30 ft / s. the ball's height
h (in feet) after t seconds is given by the following.
h = 3+30t-16t^2. find all values of t for which the ball's height is 11 feet.
round your answer(s) to the nearest hundredth.
(if there is more than one answer, use the "or" button.)

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

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
