if a $1000 investment earns %20 interest compounded annually, then the investment will double in value in how many years?

Step-by-step explanation:

End of first year:

1000 + 20%•1000 = 1000 + 200 = $1200

End of second year:

1200 + 20%•1200 = 1200 + 240 = $1440

End of third year:

1440 + 20%•1440 = 1440 + 288 = $1728

End of fourth year:

1728 + 20%•1728 = 1728 + 345.6 = $2073.6  >2•$1000

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
