B is -5 and C is -2. Since -5 is the first number, a(1) is bc^0 and that would make c = 1. B would need to be -5. In the second number, since we know b is -5, c would need to be -2 and anything to the 2-1 is just the same value.
When the object reaches the ground, the height is zero, so:
0 = 144 - 16t^2
then you just solve for t, so subtract the 144 over
-144 = -16t^2
then divide by the -16
9 = t^2
then take the square root of both sides
3 = t
therefore, it will take three seconds for the object to reach the ground.
Answer:
It is the second one
Step-by-step explanation:
Volume= length x width x height (i.e. V=lwh)
Therefore, 1/2 * 5 1/2 * 10 1/2 = 231/8 . Simplify your fraction to get 28 7/8 ft.
