A ball is thrown into the air from the top of a building. The height, h(1), of the ball above ground, t seconds after it is thrown, can be madeled by the function h(t) = -16t2 + 64t + 80. Based on the function, the "80"
represents what?
a. The time when the ball hits the ground
b. The distance the ball travels.
C. The speed of the ball
d. The initial height of the ball

d

Step-by-step explanation:

8

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
