The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y. y=3 x10^8/x what are the wavelengths for x-rays within frequency 3 x 10^18

First option: 1*10^(-10) m

Step-by-step explanation:

y=3*10^8/x

Wavelength (in meters): x=?

Frequency: y=3*10^18

Replacing y by 3*10^18 in the equation:

3*10^18=3*10^8/x

Solving for x: Cross multiplication:

3*10^18*x=3*10^8

Dividing both sides of the equation by 3*10^18:

3*10^18*x/(3*10^18)=3*10^8/(3*10^18)

Simplifying:

x=10^8/10^18

x=10^(8-18)

x=10^(-10)

x=1*10^(-10) m

Step-by-step explanation:

The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.

x is the wavelength and y is the frequency

we are given with frequency 3*10^18

we plug in 3*10^18 for y

cross multiply it

divide by 3*x10^18 on both sides

or x= 1*10^-10 m

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

if x = 1, then the answer is 3.5
