<h3><u>Question:</u></h3>
The formula h = 120t-16t^2 gives the height h in feet of an object t seconds after it is shot upward from Earth's surface with an initial velocity of 120 feet per second. What will the height of the object be after 6 seconds?
<h3><u>Answer:</u></h3>
The height of object after 6 seconds is 144 feet
<h3><u>Solution:</u></h3>
<em><u>The formula that gives the height of an object is:</u></em>

Where,
h is the height in feet and t is the time in seconds
To find: height of the object be after 6 seconds
To find the height of the object be after 6 seconds, substitute t = 6

Thus height of object after 6 seconds is 144 feet

<span>n^2+7n+15=5
n^2 + 7n + 10 = 0
(n + 5)(n + 2) = 0
n + 5 = 0
n = -5
n + 2 = 0
n = -2
Answer: n = -5 and -2</span>
