1 answer:

3 0

Answer: We are supped to solve for y so it will be division because that's the inverse for x. so: x/4 is your answer.

Answer:

$1,073,741,824

Step-by-step explanation:

Every 12 years, the price increases by double. So, first we would need to find the difference of years between 2370 and 2046.

2370-2046=324

Divide this number by 12 to see how many times the number is doubled.

324/12=27

Continue this pattern of "every 12 years, the price increases by 2x" 27 times.

Ex: 2058-->$16

Ex: 2070-->$32

Ex: 2082-->$64

etc....

A model train is 6 inches the real train is 42 feet what is the scale factor in inches

fredd [130]

1 foot = 12 inches
42 feet = (42 x 12) = 504

The factor of (6 inches / 42 feet) is (6 inches / 504 inches) = 1 / 84 .

The scale factor is not in inches. It's a factor, and has no units.
A 1-ft model would represent a real 84 feet.
A 1-meter model would represent a real 84 meters.
A 1-yard model would represent a real 84 yards.

Find the indefinite integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.) dx x(l

Pepsi [2]

I'm assuming the integral is

$\displaystyle \int \frac{dx}{x (\ln(x^2))^5}$

We have

$\ln(x^2) = 2 \ln|x| \implies (\ln(x^2))^5 = 32 (\ln|x|)^5$

Then substituting $y=\ln|x|$ and $dy=\frac{dx}x$ , the integral transforms and reduces to

$\displaystyle \int \frac{dx}{x(\ln(x^2))^5} = \frac1{32} \int \frac{dy}{y^5} \\\\ ~~~~~~~~ = \frac1{32} \left(-\frac1{4y^4}\right) + C \\\\ ~~~~~~~~ = -\frac1{128(\ln|x|)^4} + C$
