Internet Usage The number of hours people in the United States spent using the internet each year from 1998 to 2001 can be modeled by the function f(x) = 26.4x + 54.4 where x is the number of years since 1998. Determine the number of hours people spent on the internet in the year 2000.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

the answer is 5/14.

hope this .
