Question

The height $h,$ in feet, of a golf ball shot upward from a ground level sprint gun is described by the formula $h=-16 t^{2}+48 t$ where $t$ is the time in seconds. When will the ball hit the ground again?

So this word problem wants to know. When will the ball hit the ground again? So the ball hit the ground when the height equal zero. Therefore, when the Heid equal zero so zero equals negative 16 t squared plus 40 80. So, in orderto factor this in software T, I&#x27;m going to pull out the greatest common factor in the greatest comment. Minami on the right hand side. So the guy&#x27;s coming factor between 16 and 48 that would be 16. So I&#x27;m gonna pull out a negative 16 and they both have a tea. So I&#x27;m gonna pull out the lowest degree, which is t so on inside we&#x27;re left with tea and in minus three. So now we can just set both of these equal to zero so we can say And I gotta say, same teeth with zero and t minus three equals here. So this is just zero. And if we add three to both sides to you, certainty equals three. So t is the time in seconds and because it automatically starts at a height of zero at zero seconds, we&#x27;re going to eliminate this option here. We really wanna bug is on when it will hit the ground again. They&#x27;re or our answer is T equals three because we want to know when it hit the ground again, so t equals three complete circuits.

given a function H t is you go to my 16 30 square plus for year T to find out if the golf ball or the height to be alternative. So to put that first of all, put it. Put HD yesterday to relieve two is equal to minus 16 t square This 48 t for your injustice in the form of 16 T square minus 48 T plus 32 is equal to zero. Now take 16 common here from all of them and put it out that at 16 t Square minus Tweety plus two people zero, it&#x27;s 16 here and become zero. So the question we will left for the Bt square minus treaty plus two equals zero not funded some of that we know terminus. Be square minus four a. C. Now here, take minus three says B to see take one. Here is a says that comes ministry Old square minus four into two into long. This says nine minus eight, which is fun. So the terminus were down zero. So that means the roots exist there. Creo So that means that the golf ball can restore two feet. Yes,

page equals negative. 16. He square plus 64 see internal it t equal for, um I have negative 16 times. Four square, 64 times four six regular, 16 time. 16 last you 56. 16 times 16 is 2 56 negative tons of positive is a negative. I have negative. 2 56 plus 2 56 which equals zero. That would be zero feet.

Sherrie Fenner · Answer

h equals negative. 16. He squared last six before t when t equals zero by a negative 16 time zero plus 64 time zero. So this equals zero plus zero, which is zero.

This is another ball question which is asking us for a ball that is thrown into the air at 96 feet per seconds. And this is the equation that represents its altitude. How far off above the ground it is. And question A asks us. When does the ball hits the ground? Will, Since s F T is my equation, I&#x27;m asking when does this output value? At what time does this output value reach zero. So I&#x27;m really asking the question here. When does s f t equal zero? And that means the output value, which is why would be zero, which would be then the X intercept. So I&#x27;m asking at what time does this land on the ground. So over here, I have a graph 90 60 minus 16 t squared and you&#x27;ll notice that it it leaves 00 and starts to fly in the air. So this is when it starts. Zero seconds is when it starts. And here we have a timer. One second, two seconds, three seconds. Four seconds. Five seconds and six seconds out. It lands on the ground. So how long does it take to grant land back on the ground at time T equals six AT T equals six, which is six seconds. Question. Be on the other hand, asks for what time? The ball is more than 100 and 28 feet. So the second question here is asking When is the height above 128? And again, I&#x27;m asking this in terms of the input value for win. The output value satisfies this information. And so I have here a second line up here, this purple line and the crosses here at two seconds and four seconds. So when is the ball above 128 feet? When it&#x27;s in between two and four seconds, it&#x27;s above it. So that means that my answer is going to be two is less than T, which is less than four, or between using words between two and four seconds.

Sherrie Fenner · Answer

H equals negative. 16 t squared. What? 64? I mean and we let t equal one. So I&#x27;m negative. 16 size one squared plus 64 finds one. So this equals negative 16 times ones where it is negative. 16 but 64. And that gives me a positive 40 and that&#x27;s in.
