Another way of presenting this question is to ask: what is the volume of the prism. Sometimes, you can get tripped up on the terminology and fail to discover what it is the question is really asking. To find the volume of this concave prism, we can divide it into two boxes: top box and bottom box. Imagine slicing a knife through the line where the two "steps" intersect. From there, we can apply the basic formula for a rectangular prism and add up the volumes.

Top Box:
A = height x length x width
A = 10 x 40 x 20
(the height is 10 because it is equal to the tallest height minus the shorter height)
A = 8000 in. cubed

Bottom Box:
A = height x length x width
A = 20 x 60 x 20
A = 24000 in. cubed

Total Volume = 24000 in. cubed + 8000 in. cubed = 32000 in. cubed

Margarita [4]

For this case, the first thing we must do is define variables.

We have then:

t: number of hours

F (t): total charge

We write the function that models the problem:

F (t) = 6t + b

Where,

b: represents an initial fee.

We must find the value of b.

For this, we use the following data:

Her total fee for a 4-hour job, for instance, is $ 32.

We have then:

32 = 6 (4) + b

From here, we clear the value of b:

32 = 24 + b

32-24 = b

b = 8

Then, the function that models the problem is:

F (t) = 6t + 8

Answer:

the function's formula is:

F (t) = 6t + 8

Haley pays a monthly fee of $20 for her cell phone and then pays 5 cents per minute used. The cost of Haley’s cell phone bill ca
Svet_ta [14]
The domain is
{x | x >=0}
Or simply [0, infinity)
Since Haley can not use any negative minutes.

The range is
{y | y >=20}
Or simply [20, infinity)
This is because if Haley doesn't use any minutes, the price will stay at $20.
Let me know if you have any questions.
