Solve 5n^2=5 with the quadratic formula

Yanka [14]

Answer:

n = 1

Step-by-step explanation:

First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.

5n² = 5

5n² - 5 = 0

State the variables a, b and c.

a = 5; b = 0; c = -5

Substitute a, b, and c into the quadratic formula.

$n = \frac{-b ±\sqrt{b^{2}-4ac} }{2a}$

$n = \frac{-0 ±\sqrt{0^{2}-4(5)(-5)} }{2(5)}$ Substitute

$n = \frac{\sqrt{100} }{10}$ Simplify inside the √ and bottom

$n = \frac{10}{10}$ Simplify the top

$n = 1$ Final answer

Therefore the solution is n = 1.

The quadratic formula usually is written with x, but it can be solved with any variable in standard form.

A youth sports league held various fundraisers. They received $350 from a car wash, $337 from a bake sale, and $490 from a used

mina [271]

Given that the received amount was $350 from a car wash, $337 from a bake sale, and $490 from a used equipment sale.

Also, the interest rate is 2.2 % and the time period is 3 years.

Thus, the total amount is as follows:

$\begin{gathered} \text{Total amount = 350+337+490} \\ \text{Total amount = }1177 \end{gathered}$

Next, the accumulated amount can be calculated as follows:

$\begin{gathered} Accumulated\text{ amount = P(1+}\frac{R}{100})^n \\ Accumulated\text{ amount }=\text{ 1177(1+}\frac{2.2}{100})^3 \\ Accumulated\text{ amount }=1177(\frac{102.2}{100})^3 \end{gathered}$

Further, solve the obtained result as follows:

$\begin{gathered} Accumulated\text{ amount }=\text{ 1177}\times(1.022)^3 \\ Accumulated\text{ amount }=1177\times1.067 \\ Accumulated\text{ amount }=1256.40 \end{gathered}$

Thus, the league will have $1256.40 in their account after 3 years.
