Step-by-step explanation:
if u need this answer, take
Original #: 950
New #: 1,520
If it is percent of increase, you would do new amount - original amount over original amount.
1,520 - 950 / 950 = 570 / 950
0.6 or 60%
The brick will fall to the ground after 9 secs.
<h3>What are quadratic equations?</h3>
Given the equation for height as a function of time is h(t) = -16t2 + 1,296
The height of the brick on the ground is h(t) = 0. Substitute h(t) = 0 into the equation as shown:
Subtract 1296 from both sides
-16t² + 1,296 - 1296 = 0 - 1296
16t² = 1296
t² = 1296/16
t² = 81
t = 9secs
Hence the brick will fall to the ground after 9 secs.
