Step-by-step explanation:
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.
So we need to figure out how much he earns. So, if he takes two passengers and he charges a flat fee of $4.00 the he already has $8.00. So now we need to figure out how much money he gets from 4.8 miles and 7.3 miles. So he charges 2.25 miles per hour. So to get the first evening we have to multiply 4.8 times 2.25 to get $ 10.80. To get the next passenger we have to multiply 7.3 times 2.25. When you multiply 7.3 by 2.25 is 16.425. So you add the totals together and get $ 13.225 or 13.22

<em><u>Let's solve your equation step-by-step.</u></em>
−88=−3(4m+5)−(1−3m)
<em><u>Step 1: Simplify both sides of the equation.</u></em>
<em>−88=−3(4m+5)−(1−3m)</em>
<em>−88=−3(4m+5)+−1(1−3m)(Distribute the Negative Sign)</em>
<em>−88=−3(4m+5)+(−1)(1)+−1(−3m)</em>
<em>−88=−3(4m+5)+−1+3m</em>
<em>−88=(−3)(4m)+(−3)(5)+−1+3m(Distribute)</em>
<em>−88=−12m+−15+−1+3m</em>
<em>−88=(−12m+3m)+(−15+−1)(Combine Like Terms)</em>
<em>−88=−9m+−16</em>
<em>−88=−9m−16</em>
<em><u>Step 2: Flip the equation.</u></em>
<em>−9m−16=−88</em>
<em><u>Step 3: Add 16 to both sides.</u></em>
<em>−9m−16+16=−88+16</em>
<em>−9m=−72</em>
<em><u>Step 4: Divide both sides by -9.</u></em>
<em>−9m/−9 = −72/−9</em>
<u>m=8</u>
AD + DG = AG.
If DG is twice as long as AD, then DG is 20.
Add DG and AD together and you can find that AG is 30.
