Answer:

Step-by-step explanation:
The function

gives the mass of the car as a function of the number of passengers in it.
And the function

gives the potential energy of the car as a function of the car's mass.
Now if the height of the ramp is 30 meters, we have


And to find the potential energy as a function of the number of passengers, we just substitute
into
to get:


which gives the potential energy as a function of the number of passengers.
length = 8 yd and width = 2 yd
So, Option D is correct.
Step-by-step explanation:
Area of rectangular playground = 16 square yards
Width of playground = w
Length of playground = l = 4w
We need to find length(l) and width(w)
The formula used is:

Putting values:

Since width of rectangle is always positive, so we will take w = 2
So. Width = 2
Length = 4w = 4(2) = 8
Hence, length = 8 yd and width = 2 yd
So, Option D is correct.

Answer:
The answer to your question is the letter D. 64π
Step-by-step explanation:
Data
diameter = 8 in
depth = 4 in
Volume = ?
Formula
Volume of a cylinder = πr²h
Process
1.- Calculate the radius
radius = 8 /2
radius = 4 in
2.- Calculate the volume
- Substitution
Volume = π(4)²(4)
- Simplification and result
Volume = π(16)(4)
Volume = 64π
