For the past 5 months, Marissa recorded the change in dollar amount on her electric bill. per month.

July: +18.02
August: +1.03
September: −0.44
October: −6.84
November: −1.19

What is the total change in her monthly electric bill over 5 months?

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 should be a. snail

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.

y-y1=m(x-x1)

y-1=1(x-8)
