Answer:
It should be t = 1.5 seconds if your equation is h(t) = -16*t^2 + 8t + 24
Step-by-step explanation:
h(t) = -16*t^2 + 8t + 24
We want to solve for t when h(t) = 0.
This is a parabolic equation so basically we can use the quadratic formula to solve this.
h(t) = -16*t^2 + 8t + 24
0 = h(t) = -16*t^2 + 8t + 24
take out the 8
0 = -2t^2 + t + 3
0 = -2t*t - 2t + 3t + 3
0 = -2t * (t + 1) + 3*( t + 1)
0 = (-2t + 3) * ( t + 1)
so time cannot be negative, so we choose 0 = (-2t + 3), t = 3/2 seconds
or t = 1.5 seconds
The answer for the question is 9 is greater than or equal to -1
The answer is 42! hope this helps!
Answer:
5≤u
Step-by-step explanation:
Put the words and numbers into an equation:
-5u+27≤2
Put all like terms on one side:
27-2≤5u ---> Do you see what I did there? Now you don't have to work with negatives. :)
Simplify:
25≤5u
Solve:
5≤u

Answer:
$45.50
Step-by-step explanation:
1. $65.00 ÷ 100 = 0.65
2. 0.65 x 30 = $19.50
3. $65.00 - $19.50 = $45.50
