Answer:

The surface area of the rectangular prism.

Step-by-step explanation:

The formula for the surface area of a rectangular prism is SA = 2 (wl + hl + hw), which actually represents the areas of each of the faces.

SA = 2wl + 2hl + 2hw

We see that the SA is the sum of the areas of the faces on a rectangular prism. Look at a picture of a rectangular prism if you have trouble understanding this.

Pachacha [2.7K]

Answer:

  y = tan(x +π/2)

Step-by-step explanation:

It can be helpful to start with a simple sketch of the function you have and of the tangent function. Then, you can see the relationship.

The tangent function is always rising, has vertical asymptotes at -π/2 and π/2, and has a zero crossing at x=0.

The function we want is always rising, has vertical asymptotes at x=0 and x=±π, and a zero crossing at x=-π/2.

We can create the function we want by shifting the tangent function to the left by π/2. The formula that does that is ...

  y = tan(x +π/2)

it took 3hour and 28 minutes to run 26miles. how many minutes did it take her to run 1 mile if she ran the same rate for the who
wolverine [178]
In order to solve this we can first convert 3h 28m to 208 minutes.
This will make it so we can find how many minutes it took her to run per mile.
The way we do that is by dividing 208 by 26. This leaves us with 8 minutes per mile.

Hope this helped at least a bit!
