How do I calculate interest rate on investment?

Calculate Total Amount Accrued (Principal + Interest), solve for A. A = P(1 + rt)

Calculate Principal Amount, solve for P. P = A / (1 + rt)

Calculate rate of interest in decimal, solve for r. r = (1/t)(A/P - 1)

Calculate rate of interest in percent. ...

Calculate time, solve for t.

What is the exact solution to the equation 2^x+2 =5^2x ? A) −2ln2/2ln5−ln2 B) −ln2/2ln5+ln2 C) ln2/2ln5+ln2 D) 2ln2/2ln5−ln2

GenaCL600 [577]

Answer: D

Step-by-step explanation:

2ˣ⁺² = 5²ˣ

ln 2ˣ⁺² = ln 5²ˣ apply ln to both sides

(x + 2) ln 2 = 2x ln 5 apply exponent to coefficient log rule

x ln 2 + 2 ln 2 = 2x ln 5 distribute (x + 2) on left side

2 ln 2 = 2x ln 5 - x ln 2 subtract (x ln 2) from both sides

2 ln 2 = x(2 ln 5 - ln 2) factor out (x) from right side

$\frac{2ln2}{2ln5 - ln2}$ = x divide both sides by (2 ln 5 - ln 2)

Consider the system of equations. Which is the Best method to use for solving the system? 4x+y=1 2x+y=8

Archy [21]

4x + y = 1
-2x - y = -8

2x = -7

x = -7/2

2(-7/2) + y = 8

-7 + y = 8

y= 15
