Answer:
Step-by-step explanation:
Solving:
Use the formula h = -16t^2 +vt +s
What we know:
v = 64 feet per second (initial velocity)
s = 80 foot (initial height)
h = ?
t ?
h = -16t^2 + 64t + 80
I know I should be asking in detail, are you allowed to use the quadratic formula or solve it by factoring it out?
The answer is 325
A
this is true due to the ratio of a 30-60-90 triangle, which is 1-2-sqrt(3). The 12 corresponds to the sqrt(3), which means that the 1 corresponds to 4sqrt3 and the 2 to 8sqrt3.
