Suppose that a polygon has area 33. the sides of the polygon have a scale factor of 1: 8 to get a similar polygon.
what is the area of the scaled polygon?

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 one below it is a function
