Dawn is verifying the accuracy of her paycheck. She earns $14 an hour and works 40 hours each week. Her biweekly deductions are Social Security 6.2%, Medicare 1.45%, federal
withholding tax $73.25, state withholding tax $22.50, and health insurance $37.45. What is
her annual net pay if she is paid biweekly (every two weeks)?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

the answer is 40.

proof:

a.)the line for function b is steeper
