Factor Completely:<br><br> 16x8−81y8

svet-max [94.6K]

Answer:

Step-by-step explanation:

16x⁸ - 81y⁸ is the difference of squares.

16x⁸ - 81y⁸ = (4x⁴)² - (9y⁴)² = (4x⁴ + 9y⁴)(4x⁴ - 9y⁴)

Note that 4x⁴ - 9y⁴ is also the difference of squares.

4x⁴ - 9y⁴ = (2x²) - (3y²)² = (2x² + 3y²)(2x² - 3y²)

16x⁸ - 81y⁸ = (4x⁴ + 9y⁴)(2x² + 3y²)(2x² - 3y²)

An Uber fare in Columbus is $3.50 for the first ½ mile and additional mileage charged at a rate of $0.30 for each additional 0.1

Verizon [17]

Answer:

$\frac{11}{3}$ miles

Step-by-step explanation:

Let the total miles traveled be x.

Now, for the first 0.5 miles total charge is = $3.50

Then, the remaining distance to be traveled $=(x-0.5)$ miles

For each additional 0.1 mile, the additional charge is $0.30

So, for $(x-0.5)$ miles, the total additional charge will be $=\frac{0.3}{0.1}(x-0.5) =3(x-0.5)$

Then, including the $2 tip, the total fare will be $=3.50+3(x-0.5)+2$

Now, given that total fare is $15, so,

$3.50+3(x-0.5)+2=15\\3.50+3x-1.5+2=15\\3x+4=15\\3x=11\\x=\frac{11}{3}$ miles

If y varies inversely as x2 and y=6 when x=30, what is y when x=6

ladessa [460]

Answer:

y = 150

Step-by-step explanation:

y varies inversely as x²

yx² = k

----------------

y = 6 when x = 30

6(30²) = k

6(900) = 5400

--------------------------

what is y when x = 6

y(6²) = 5400

y(36) = 5400

y = 5400/36

y = 150
