When it hits the ground the height would be 0.
Set h to 0 and solve for t ( time)
0 = -16t^2 + 112t + 144 divide both sides by -16:
T^2 -7t -9
Factor the polynomial :
( t- 8.1) (t+1.1
Solve for t setting each equation to 0:
T = 8.1 or t = -1.1
Time has to be positive, so the answer is
8.1 seconds
Depending on how everything gets rounded it could also be 8 seconds.
Let this guide you through
With even just two points, you can find the equation of a line in slope-intercept form.
Slope-intercept form: 
where 
is the slope and 
is the y-intercept
<u>1) Solve for the slope (</u><u>)</u>
The equation to solve for the slope is 
when the two points are 
and 
. Plug the coordinates of these points into the equation and solve for .
Then, plug into .
<u>1) Solve for the y-intercept (</u><u>)</u>
Then, take any of the given points and plug it into along with the slope. Isolate to get the y-intercept. Then, plug both m and b back into to get your final equation.
I hope this helps!
we know that
domain is all possible values of x for which any function is defined
so, here domain will be all possible values of x fro which y is defined
so, we will find minimum and maximum value of x
we can see that
x starts from 0
so, minimum value is x=0
and it goes to right upto infinity
so, domain will be

Answer: When two sets of data are strongly linked together we say they have a High Correlation. The word Correlation is made of Co- (meaning "together"), and Relation. Correlation is Positive when the values increase together, and. Correlation is Negative when one value decreases as the other increases.
