Under a dilation, the point (−3, −4) is moved to (−15, −20). What is the scale factor of the dilation? Enter your answer in the box.

step-by-step explanation:

if x = 2 you have to find x to finish the problem

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:

i need points
