Answer:
x = 5/-6 + (√13)/-6
x = 5/-6 -(√13)/-6
Step-by-step explanation:
2x^2 = -x^2 - 5x - 1. Subtract 2x^2 from both sides.
-3x^2 - 5x - 1. Do the quadratic formula.
That gives you:
-5/6 ± (√13)/-6.
Since the triangles are similar, they will have proportional sides. With this knowledge, we can make the proportion
to solve for x.
Firstly, cross multiply: 
Next, divide by 10 on both sides, and your answer will be 4 = x, or the first option.
We are given a graph for the height of the ball with respect to horizontal distnace x of the ball from Julie.
From the graph, we can see the position of Julie is at (0,0). And starting height of the ball when thrown is 6 feet.
Then it moved to the maximum height of 14 feet. And hit to the ground when it has position on x-axis is 3.5 feet.
<em>Because we can see the parabola is crossing x-axis at 3.5 on the right.</em>
<em>That represents distance of the ball from Julie when it hit to the ground.</em>
<h3>Therefore, it has a horizontal distance of 3.5 feet from Julie.</h3>
