If measure angle 2 = 7x + 7, measure angle 3 = 5y, and measure angle 4 = 140, find the values of x and y.

10.4 inches

step-by-step explanation:

2x2x2.6

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:
