Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>Finding the value of t when h(t) = 10 feet:</u>
- 10 = -16t^2 +12t +8
- -16t^2 +12t - 2 = 0
- 8t^2 - 6t + 1 = 0
- t = (6 ± √6²-8*4)/16 = (6 ± √4)/16 = (6 ± 2)/16
- t = 1/2
- t = 1/4
There are two solutions. 1/2 of a second would be the answer as the ball should go up and then down to go through the hoop.
Answer:
i believe the answer is 13.4 units
i hope this helps :))))
Answer:
68 degrees
Step-by-step explanation:
I am thinking C, I hope you get that problem right! :)
Better to see it for yourself :) .
can be solved easily by taking the logarithm in base 3 on both sides. We can do that because the log and the exponential functions are strictly increasing. It gives
which is easy to solve.
BUT if you have
then you cannot simply take the logarithm of one base. Let's see why.
gives
and the simplification is not easy. I think the easiest way (if not the only) is to change the base of the logarithm with the formula
In our example it gives
Which yields
From there, it is a simple degree one equation.
