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:deeznuts
Step-by-step explanation:
Obviously you cross out the positive answers and look at the negative answers, since the slope is negative. It’s A. Because the y intersect is at -2 and -6... hope that helps
Answer:
x=1
Step-by-step explanation:
8x+6+2x=12+4x
10x+6=12+4x
-6 -6
10x=6+4x
-4x -4x
6x=6
x=1
X=-17 I miss read long night not enough coffee lol
