We will have that the only graph that could represent the heigth of a rocket is graph A. Assuming that the x-axis represents the ground, then after some time it will go back to it.
Answer: I believe the answer is a
Step-by-step explanation:
Answer:
815
Step-by-step explanation:
First you put the value of x from the table into the formula provided.
<em>y = -670 + 33(x) </em><= plug in the x value from the table
<em>y = -670 + 33(45)</em> <= multiply 33 * 45
<em>y = -670 + 1485</em> <= add the two terms (which you will subtract because one is positive and one is negative.
<em>y = 815</em>
Answer:
The volume of the sphere is eight times the volume of hemisphere
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x-----> volume of the hemisphere
y-----> volume of the sphere
![z^{3}=\frac{x}{y}](https://tex.z-dn.net/?f=z%5E%7B3%7D%3D%5Cfrac%7Bx%7D%7By%7D)
in this problem we have
![z=\frac{1}{2}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B1%7D%7B2%7D)
substitute
![(\frac{1}{2})^{3}=\frac{x}{y}](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B3%7D%3D%5Cfrac%7Bx%7D%7By%7D)
![(\frac{1}{8})=\frac{x}{y}](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B8%7D%29%3D%5Cfrac%7Bx%7D%7By%7D)
![y=8x](https://tex.z-dn.net/?f=y%3D8x)
that means------> The volume of the sphere is eight times the volume of hemisphere
