How many years will it take for 20$ to grow to 100 if the simple interest rate is 4% annually
cestrela7 [59]

The formula for simple interest is:

Total = Principal(1+ Rate x time)


You are given:

Total = $100

Principal = $20

Rate = 4%


You are asked to find the time.

Replace everything known in the formula:


100 = 20(1 +0.04 x Time)

Now solve for Time:

Divide each side by 20:

5 = 1 + 0.04 x Time

Subtract 1 from each side:

4 = 0.04 x time

Divide each side by 0.04:

Time = 4 / 0.04

Time = 100 years.

Use the quadratic formula to find both solutions to the quadratic equation<br> given below.
Tpy6a [65]

The solution of the equation are x = \frac{7 + \sqrt{61}}{6} and x = \frac{7 - \sqrt{61}}{6}

<h3>How to determine the solution?</h3>

The equation is given as:

3x^2 - 7x- 1 = 0

The quadratic equation is represented as:

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

So, we have:

x = \frac{7 \pm \sqrt{(-7)^2 - 4 *3 *-1}}{2*3}

Evaluate the expression

x = \frac{7 \pm \sqrt{61}}{6}

Expand

x = \frac{7 + \sqrt{61}}{6} and x = \frac{7 - \sqrt{61}}{6}

Hence, the solution of the equation are x = \frac{7 + \sqrt{61}}{6} and x = \frac{7 - \sqrt{61}}{6}
