If f(x)=(2x^2)-1, find:<br> -f(3x-1)+2
Sergeeva-Olga [200]

Answer:

-f(3x - 1) + 2 = -18x² + 12x + 1

Step-by-step explanation:

Step 1: Find f(3x - 1)

f(3x - 1) = 2(3x - 1)² - 1

f(3x - 1) = 2(9x² - 6x + 1) - 1

f(3x - 1) = 18x² - 12x + 2 - 1

f(3x - 1) = 18x² - 12x + 1

Step 2: Plug in f(3x - 1)

-(18x² - 12x + 1) + 2

Step 3: Evaluate

-18x² + 12x - 1 + 2

-f(3x - 1) + 2 = -18x² + 12x + 1

You went to Walmart and spend $75. Of the total bill, $45.50 included non-taxable items. How much is the final bill if you apply
Alina [70]

We have been given that you went to Walmart and spend $75. Of the total bill, $45.50 included non-taxable items.

Let us find the amount of taxable items by subtracting amount of non-taxable items from total bill.

\text{Amount of taxable items}=\$75-\$45.50

\text{Amount of taxable items}=\$29.50

We have been given that the rate of tax is 7.5% to the taxable items. To find the amount of tax, we will find 7.5% of $29.50.

\text{Amount of tax}=\$25.50\times \frac{7.5}{100}

\text{Amount of tax}=\$25.50\times 0.075

\text{Amount of tax}=\$2.2125  

Final amount of bill would be amount of bill plus amount of tax.

\text{Final amount of bill}=\$75+\$2.2125

\text{Final amount of bill}=\$77.2125

Therefore, final amount of bill would be \$77.2125.

An angle of a right triangle measures 65 degrees. If the length of the side opposite to the angle is 20 ft, what are the lengths
igomit [66]

Answer:

22.07 ft & 9.32 ft

Step-by-step explanation:

by sines rule :

20/sin 65° = r/sin 90° = y/sin 25°

r = 20×sin 90°/sin 65° = 20/0.9063

= 22.07 ft

y = 20×sin 25°/sin 65° =

20× 0.4226/0.9063

= 9.32 ft

Haley makes earrings and packages them into cube boxes that measure 1/6 foot wide. How many 1/6 foot cubic boxes can she fit int
alexandr402 [8]

Answer:  28 cube boxes.

Step-by-step explanation:

The volume of a cube can be found with this formula:

V_{(c)}=s^3

Where "s" is the lenght of any edge of the cube.

 You need to find the volume of a cube box:

V_1=s^3=(\frac{1}{6}ft)^3=\frac{1}{216}ft^3

To find the volume of the shipping box, first we must convert the mixed number to  an improper fraction. To do it, multiply the whole number part by the denominator of the fraction and add this product to the numerator.

The denominator does not change.

Then:

1\ \frac{1}{6}=\frac{(1*6)+1}{6}=\frac{7}{6}

Knowing the dimensions of the shipping box, you can calculate its volume by multiplying its dimensions. Then, this is:

V_2=(\frac{7}{6}\ ft)(\frac{1}{3}\ ft)(\frac{1}{3}\ ft)=\frac{7}{54}\ ft^3

Finally, in order to find the  number of cube boxes can Haley fits into a shipping box, you must divide the the volume of the shipping box by the volume of one cube:

\frac{\frac{7}{54}ft^3}{\frac{1}{216}ft^3}=28
