Answer: Velocities are not equal
Explanation: A projectile usually have a given initial velocity, the velocity must be resolve into components of x and y with respect to the velocity of the projectile in a certain angle. In a projectile trajectory the final velocity for the y- component is always 0m/s since the object reaches its maximum point.
<span> For this case the volume of the box is given by:
</span>
![V = lwh ](https://tex.z-dn.net/?f=V%20%3D%20lwh%0A)
<span> Substituting values we have:
</span>
![V = (2a + 11) (5a - 12) (a + 6) ](https://tex.z-dn.net/?f=V%20%3D%20%282a%20%2B%2011%29%20%285a%20-%2012%29%20%28a%20%2B%206%29%0A)
<span> Rewriting we have:
</span>
![V = (10a ^ 2-24a + 55a-132) (a + 6) V = 10a ^ 3-24a ^ 2 + 55a ^ 2-132a + 60a ^ 2-144a + 330a-792](https://tex.z-dn.net/?f=V%20%3D%20%2810a%20%5E%202-24a%20%2B%2055a-132%29%20%28a%20%2B%206%29%0A%0AV%20%3D%2010a%20%5E%203-24a%20%5E%202%20%2B%2055a%20%5E%202-132a%20%2B%2060a%20%5E%202-144a%20%2B%20330a-792)
<span> Grouping terms of equal degree we have:
</span>
![V = 10a ^ 3 + 60a ^ 2 -24a ^ 2 + 55a ^ 2 -132a -144a + 330a-792](https://tex.z-dn.net/?f=V%20%3D%2010a%20%5E%203%20%2B%2060a%20%5E%202%20-24a%20%5E%202%20%2B%2055a%20%5E%202%20-132a%20-144a%20%2B%20330a-792%20%20)
<span> Adding terms of equal degree we have:
</span>
![V = 10 ^ 3 + 91a ^ 2 + 54a-792 ](https://tex.z-dn.net/?f=V%20%3D%2010%20%5E%203%20%2B%2091a%20%5E%202%20%2B%2054a-792%0A)

Answer: the volume of the box is: All the expressions given.</span>
C.) chemical to electrical to light
The cheetah's speed is 100x and
The gazelle's speed is 80x + 70.
Set the two equations equal to each other:
100x = 80x +70 (then subtract 80x from both sides).
20x = 70 (then divide by 20).
X =3.5.
The cheetah catches the gazelle after 3.5
We want to know what does the fact that Mercury has no atmosphere tell us. Since Mercury has no atmosphere it cant reflect a lot of sunlight that is hitting its surface. Its constantly being hit by solar wind. So Mercury reflects a small percentage of the sunlight that strikes it.
