HELP PLEASE!! lesson-quadratic formula, modeling a launched object
(solving real-life problems)

WHAT IF? The ball leaves the juggler's hand with an initial vertical velocity of
40 feet per second. How long is the ball in the air?

answer: .75 km

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

i think the answer would be c
