1. for the carnival, the park rented a dunking booth shaped as a rectangular prism. the booth is 3 1/2 ft wide, 3 1/2 ft long, and 8 ft tall. (a) what is the total volume of the dunking booth? (b) if they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Part a) The total volume is

Part b)

Step-by-step explanation:

Part a)

Find the total volume

we know that

The volume of a rectangular prism is equal to

we have

substitute in the formula

Part b) If they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Multiply the total volume by 6/7

so

square root

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
