2) A baseball coach uses a pitching machine to simulate pop flies during practice. The quadratic function y = -16t^2 + 80t + 5 models the height in feet of the baseball after x
seconds.
When does the ball reach its maximum height?
What is the maximum height?
When does the ball hit the ground?

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

y + 11 = (1/4)(x + 16)
