A paratrooper jumps from a plane at an altitude of 4500 ft and descends at the rate of 20 ft/sec. What is the formula for the paratrooper’s height, h, above the ground after t seconds? a.
h = StartFraction 4500 Over 20 EndFraction minus t
c.
h = 4500 + 20 t
b.
h = negative 20 t + 4500
d.
h = StartFraction 4500 Over 20 EndFraction t

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:
