Answer:
<h3>2.5secs</h3>
Step-by-step explanation:
Given the height of the ball modeled by the equation h = -16t^2+ 100, where
h is the height
t is in seconds
We can find the time taken by the ball to reach the ground.
The ball reaches the ground when the height h = 0
Substitute h = 0 into the equation and find t;
0 = -16t^2+ 100
16t^2 = 100
t^2 = 100/16
t = √100/16
t = 10/4
t = 2.5secs
Hence the ball reaches the ground after 2.5secs
THEY ARE ALWAYS PARALLELOGRAMS

Answer:
Shane must have collected At least 911 cans.
Step-by-step explanation:
Number of cans collected by Shane = S
Abha collected more cans than Shane = S+178
Both Shane and Abha have to collect no less than 2000 cans for recycling.
Writing the statement in terms of inequality:
S+S+178≥ 2000
2S+178≥2000
2S≥2000-178
2S≥ 1822
S≥1822/2
S≥911
Shane must have collected At least 911 cans...
