Answer:
6(37.5) + 45 = $270
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.
Answer:
3/4
Step-by-step explanation:
Jessica shaded 6/8 of the circle. That fraction can be reduced by removing a factor of 2 from numerator and denominator. The reduced fraction is 3/4.

The formula for multiplying exponents are such below.
(b^m)^n = b^mn
b^m/b^n=b^(m-n)
b^m x b^n=b^(m+n)
