The perimeter of the swimming pool shown below is 70 feet. Develop a formula to find the width, y, in term of its length, x. Explain your work.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

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:
