Part C Use an exponential expression to calculate the area covered by purple loosestrife 7 years from now.

i got 86 for this

hope this !

if you need an explanation just ask

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:

answer: 1475

step-by-step explanation:

becuase you have to know what they are asking you

this is a good question! i'll do some research and come back when i have the answer!
