8r−rs8, r, minus, r, s when r=6r=6r, equals, 6 and s=5s=5s, equals, 5.

it's both, now can you answer my most recent question?

0 is its x and y coordinate

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:
