Suppose you deposit $2,454.00 into an account today. In 6.00 years the account is worth $3,868.00. The account earned % per year.

Interest rate, R = 26%.

Explanation:

Given the following data;

Principal = $2,454.00

Simple interest = $3,868.00

Time = 6 years

To find the interest rate?

Mathematically, simple interest is calculated using this formula;

Where;

Substituting into the equation, we have;

Cross-multiplying, we have;

Interest rate, R = 26.27 ≈ 26%

Therefore, the account earned 26% per year.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
