Answer:
5 seconds
Step-by-step explanation:
The relationship between "d" and "the ground" is not described. If we assume that "d" is distance above the ground, then the rock will hit the ground when d=0. This gives rise to the quadratic equation ...
-t^2 +4t +5 = 0
-(t -5)(t +1) = 0
t = 5 or t = -1 are solutions. Only the positive solution is useful.
The rock will hit the ground after 5 seconds.
When adding two together multiply:
log2 6 + log2 2 = log2(6*2) = log2 12
When you subtract 2 logs, divide:
So you have log2 12 / log2 8
Rewrite as log2 12/8
Simplify to get log2 3/2
The answer is C.
<span>Looking at the choices closely, you can find one relation or sameness with the given situation m*8=24. Isolating “m” gives you a new equation m=24/8 which is related to equation m=25/8. It has same m value on the left of the equation and it contains 2 whole numbers and arithmetic operation (/) on the right of the equation.</span>
Answer:
5
Step-by-step explanation:
5²=25 and 6²=36
25 is way closer to 27 than 36
so
5
