Suppose your VISA card calculates interest using the average daily balance method, and the monthly interest rate is 2.9%. The itemized billing for the month of April is shown below. Detail Date Unpaid balance April 1 Charge April 3 Charge April 11 Charge April 15 Payment received April 28 Last day of billing period April 30 Payment due date May 7 Amount $380 $890 $950 $1130 $860 (a) Find the average daily balance. $ (b) Find the interest due for this month. $ (c) Find the total balance owed on the last day of the billing period. $ (d) This credit card requires a $20 minimum payment or 1/36 of the amount due, whichever is higher. What is the minimum monthly payment due for this month? $​

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 radius is 2 times the diameter.
