Central Park is shaped like a rectangle. Two diagonally-opposite corners of the park are located at (-8,6) and (5,-4) on the coordinate plane. If each square on the graph represents one city block, what is the perimeter of Central park?

your answer would be 12

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:
