Answer:
21.5secs
Step-by-step explanation:
Given the function that models the height of an object as
h(t) = -16t^2+ 344t
The object hit the ground at h(t) = 0
Substitute
0 = -16t^2+ 344t
16t^2 = 344t
16t = 344
t = 344/16
t = 21.5
Hence it takes 21.5secs for the object to hit the ground
Answer:
66 degree
Step-by-step explanation:
we will find it out by Angle sum property.
The first one is incorrect
I'm assuming you're trying to find H so this is how you start:
first solve what [<span>-16.1(15)^2+150] is
</span>
<span>-16.1 (15)^2 + 150
-16.1 x 225 + 150 =
-3622.5 + 150 =
-3472.5 = H(15)
now you divide -3472.5 by 15 to get H
-3472.5 / 15 =
-231.5 = H
