Answer:
Step-by-step explanation:Since we want to know how much time elapsed since the object was launched until it ht the ground. At the ground, the height is 0.
Therefore the equation h(t) = 80t – 16t2 becomes 0= 80t – 16t2
Solving the equation for t gives 80t =16t2 or 16t=80 or t=5sec
The object hits the ground 5 seconds after it is launched.
Answer: B
Step-by-step explanation: Length x Width = Area
8 feet x width = 96 sq ft
8w = 96
The answer is 280 degrees.
4/20 is 0.20, which is equivalent to 20%.
Remember that 1.0=100%, 0.5=50%, 0.2=20%, 0.05=5%, and so on.
Answer:
Step-by-step explanation:
<em>Hey there!</em>
Well given that,
a = 25
b = 3
10(25) - 5(3)
250 - 15
= 235
<em>Hope this helps :)</em>
