A6-foot pine tree was planted and grew 2 feet each year. write an algebraic expression for the height after y years.

use H for height and y for years

 so H=6+2y

answer:

your answer is: c. 196 7/8 in^3.

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:
