   b, d, c, a, e

Step-by-step explanation:

A formula should always come with a definition of the variables it uses. Here, you're supposed to somehow magically figure out what the variables are.

  A = P(1 +r/n)^(nt)

A is the amount of the investment of principal P after t years, compounding annual rate r n times per year.

__

Then your blanks get filled like this:

  1. A -- b the value

  2. P -- d the principal

  3. r -- c the annual interest rate

  4. n -- a number of times compounded per year

  5. t -- e number of years

did you get the answer yet?

step-by-step explanation:

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.
