I think it is..................
Answer:
Step-by-step explanation:
The domain is the limits of the function. Since time doesnt go negative, start with 0. At time 0, the height is
-16(0)^2 + 144 = 144ft
Then, solve for t to find the upper limit for t, which is when the height is zero (since you're dropping the object).
-16t^2 + 144 = 0
-16t^2 = -144
t^2 = 9
t = sqrt(9)
t = 3
The domain is 0 to 3 seconds.
M=18
explication: both of the angles are 90 degrees, 90-33=57, 3(18)+3=57
A is correct. Hope my answer helped u :)
