Which statement describes a relationship between -6 and -9 if you know that -6 is to the right of -9 on a number line.
A) -6 < -9
B) -6 > -9
C) -6 ≤ -9
D) -6 ≥ -9

first one because it can't have a fraction in it

step-by-step explanation:

the answer is b.

step-by-step explanation:

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 answer is 1030 it's very simple math.
