Hello there! :)
To multiply fractions, we do the following:
- We multiply the numerator of one fraction by the numerator of the other one.
- We multiply the denominator of one fraction by the denominator of the other one.
- Simplify if necessary.
Here's an example:
Step number one: multiply 3 times 5
15
4*6=24
The answer can be reduced. Divide both the top and the bottom by 3:
Therefore, that's the answer. Hope it helps! :)

Answer:
- 40 ft
- t = 1 second
Step-by-step explanation:
A graphing calculator answers these questions easily.
The ball achieves a maximum height of 40 ft, 1 second after it is thrown.
__
The equation is usefully put into vertex form, as the vertex is the answer to the questions asked.
h(t) = -16(t^2 -2t) +24
h(t) = -16(t^2 -2t +1) +24 +16 . . . . . . complete the square
h(t) = -16(t -1)^2 +40 . . . . . . . . . vertex form
Compare this to the vertex form:
f(x) = a(x -h)^2 +k . . . . . . vertex (h, k); vertical stretch factor 'a'
We see the vertex of our height equation is ...
(h, k) = (1, 40)
The ball reaches a maximum height of 40 feet at t = 1 second after it is thrown.
