A television regularly costs $180, but it is on sale for 40% off. There is a 5% sales tax on the sale price. How much does the t
Anuta_ua [19.1K]

Answer:

$113.4

Step-by-step explanation:

If it is 40% off then it is 100-40 = 60% of original price.

So we do 180$ * .6 = $108 before tax.

To add on tax we do: 100 + 5 = 105% of that price.

So we do: $108 * 1.05 = $113.4 after discount and tax.

A designer is creating various open-top boxes by cutting four equally-sized squares from the corners of a standard sheet of 8.5
Oxana [17]

Answer:

L(x) = 11 - 2x

W(x) = 8.5 - 2x

V(x) = 4x³ - 39x² + 93.5x

Step-by-step explanation:

If a square of x sides length is cut from each corner of the sheet, then it meas the length and width of the box a shortened by x inces from each side, giving a total subtraction of 2 times x inches.

FORMULA FOR LENGTH:

Since, Length is the bigger side of the box. Therefore, it will be taken on 11 inches side of the paper:

<u>L(x) = 11 - 2x</u>

FORMULA FOR WIDTH:

Since, width is the smaller side of the box. Therefore, it will be taken on 8.5 inches side of the paper:

<u>W(x) = 8.5 - 2x </u>

FORMULA FOR VOLUME:

Volume is the product of length, width and time:

V(x) = L(x)*W(x)*H(x)

Height must be equal to the side folds which are equal to length of the side of square = x:

H(x) = x

Therefore,

V(x) = (11 - 2x)(8.5 - 2x)(x)

V(x) = (93.5 -22x -17x + 4x²)(x)

<u>V(x) = 4x³ - 39x² + 93.5x</u>

Match each verbal description to its equivalent function rule as applied to the given function below.
stepladder [879]
The top-left graph goes with the bottom-right equation, y=90(1/4)^x

The bottom-left graph goes with the top-right equation, y = 120(3/4)^x

The top-right graph goes with the bottom-left equation, y = 120(1/4)^x

The bottom-right graph goes with the top-left equation, y = 90(3/4)^x

y=90(1/4)^x has a larger percent decrease than y = 90(3/4)^x
cause if you multiply a number by 1/4, that's smaller than multiplying number by 3/4. so y=90(1/4)^x decreases really fast

same with the y = 120(3/4)^x ones
