How to find compound rate from given values, 10 years after, and initial

dybincka [34]

The formula that calculates the compound rate from the given values is $r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

<h3>How to determine the compound interest rate?</h3>

The compound interest formula is:

$I = P(1 + \frac rn)^{nt} - P$

Where:

P represents the principal amount
r represents the compound interest rate
n represents the number of times the interest is compounded
t represents the time in years
I represents the interest

We start by adding P to both sides

$P + I = P(1 + \frac rn)^{nt}$

Divide through by P

$\frac{P + I}{P} = (1 + \frac rn)^{nt}$

Take the nt-th root of both sides

$\sqrt[nt]{\frac{P + I}{P}} = 1 + \frac rn$

Subtract 1 from both sides

$-1 + \sqrt[nt]{\frac{P + I}{P}} = \frac rn$

Multiply through by n

$r = n(-1 + \sqrt[nt]{\frac{P + I}{P}})$

In this case, t = 10

So, we have:

$r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

Hence, the formula that calculates the compound rate is $r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

Find the solution to the following system of equations using substitution or elimination

Serggg [28]

Answer:

D. (2,-3)

Step-by-step explanation:

if you substitute 2 for the x value and -3 for the y value in both equations, it works out.

instead of y=3x-9 it would be -3=3(2)-9.

you solve and get -3=-3, so it's a solution.

and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.
