Find slope A.1/2 B.-1/2 C.-2 D.2

fomenos

Answer:

Option B, -1/2

Step-by-step explanation:

The slope is change in y over change in x.

Since this line is facing downward, we already know that the slope is negative.

To find the ratio, find the change in y and divide the change in x.

Change in y = -1

Change in x = 2

Change in y over change in x: -1/2

Answer: Option B, -1/2

A satellite launch rocket has a cylindrical fuel tank. The fuel tank can hold V cubic meters of fuel. If the tank measures d met

weqwewe [10]

Let the volume of the cylinder be V cubic meters, the diameter be d meters and the height be h meters.
Now we can write the formula for the volume as follows:
$V=\pi\frac{d^{2}}{4}h$
Rearranging the formula, the height becomes:
$\large h=\frac{4V}{\pi d^{2}}$
