7. You extend the sides of a regular octagon as shown in the figure. You are given that w is perpendicular to y and y || z. Do you have enough information to conclude that x is perpendicular to z? Explain.

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 easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
