Una persona invierte 5000 dólares en una cuenta que paga 8.5% de interés anual, capitalizable cada trimestre. a. Encuentre la cantidad después de tres años

b. ¿Cuánto tiempo tomará para que se duplique la inversión?

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

noncoplanar points are points that do not lie on the same line.

okay..i will pick 8!
