How long will it take for $6400 to grow to $43,800 at an interest rate of 3.4% if the interest is compounded continuously? Round the number of years to the nearest hundredth.

57.53years to the nearest hundredth

Step-by-step explanation:

For compound interest,A=P(1+r/100)^t

where r=rate of interest

t= investment tenor

$43800=6400(1+3.4/100)^t

which simplifies to 57.5250≈57.53 to the nearest hundredth

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

the answer is d on edge
