Rational expression refers to a fraction in which the numerator and denominator are polynomials.
The ball describes a parabola, as you can see in the attached picture. So, the point where the ball strike the ground is the point where the parabola meets the x axis. In fact, the x-axis is the set of points where y=0, which means that the ball has height 0 or -again- it hits the ground.
So, we have to set y=0 in our equation and look for the positive solution. We have
And the positive solution is
So that's the distance from the child where the ball strikes the ground.

Answer:
1
Step-by-step explanation:
You can do this two ways:
(13 -6) mod 6 = 7 mod 6 = 1
(13 -6) mod 6 = (13 mod 6) -(6 mod 6) = 1 - 0 = 1
____
"mod 6" means you are interested in the remainder after division by 6. For some number n, it can be computed as ...
n mod 6 = n - 6×Floor(n/6)
Answer:
6 apples, 21 apples, 30 apples respectively
Step-by-step explanation:
Let us first start by writing <u>expressions</u> so that we can easily solve for the problems below.
Let us suppose Alice is x. In this case, Claire has 3 times Alice's apples, so 3x.
1. If Alice has 2 apples (x), then Claire has 3x
3*2=<u>6 apples</u>
Claire has 6 apples.
2. If Alice has 7 apples (x), then Claire has 3x
3*7=<u>21 apples</u>
Claire has 21 apples.
<u />
3. If Alice has 10 apples (x), then Claire has 3x
3*10=<u>30 apples</u>
Claire has 30 apples.
