A batter hits a baseball upward with an initial speed of 96 feet per second. After how many seconds does the ball hit the ground? Use the formula h = rt − 16t2 where h represents height in feet and r represents the rate in feet per second.

@csscgirl

OpenStudy (anonymous):

ur n precal too?

OpenStudy (anonymous):

this looks hard

OpenStudy (anonymous):

ummmm... 0=(96)t-16t^2

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

Numerical Answers Expected!

OpenStudy (anonymous):

XD alright :P

OpenStudy (anonymous):

its only like a couple of secs

OpenStudy (anonymous):

6

OpenStudy (anonymous):

just graphed it

OpenStudy (loser66):

replace r = 96, solve for t

OpenStudy (loser66):

because when hitting the ground, h =0

OpenStudy (anonymous):

yes H=96t-16t^2

OpenStudy (loser66):

h =0 , too,

OpenStudy (anonymous):

how

OpenStudy (loser66):

h is the height of ball when moving, when the ball is on the ground, h =0. Dat sit

OpenStudy (anonymous):

just graph it and youll cee

OpenStudy (anonymous):

idk how to graph online

OpenStudy (anonymous):

desmos.com/calculator its THE BEST graphing calculator on line

What is the y−coordinate of the y−intercept of the line that passes through the points (−4, −4) and (4, 8)?

OpenStudy (anonymous):

y=mx+b.... the slope will be change in y over change in x... so m will be 3/2 b will be what you get when you do 8=3/2(4)+b b will be your final answer @Albany_Goon
