En considérant que DE est

When a body is said to be in a state of free fall, therefore this means that the only force associated with it is gravity. Gravity imposes an acceleration of about 9.81 m/s^2. Therefore we do not need to calculate for a, since a = g. (g = acceleration due to gravity)

How much do you need to invest every month in an annuity to

Katen [24]

Answer:

A=25000 is the future value. P the value that we need to invest. r= 0.04 represent the interest rate in fraction. n = 12 represent the number of times that the rate is compounded in a year. t = 5 years.

If we solve for the value of P we got:

$P= \frac{A}{(1+ \frac{r}{n})^{nt}}$

And replacing we got:

$P= \frac{25000}{(1+ \frac{0.04}{12})^{12*5}} =20475.078$

And rounded to the nesrest penny we need to invest $20475.08 in order to have after 5 years $25000

Step-by-step explanation:

For this case we can use the future value with compound interest given by:

$A = P (1+ \frac{r}{n})^{nt}$

Where:
