N^2- 5n +4=0 quadratic equation
luda_lava [24]

Answer:

n = 1, 4

Step-by-step explanation:

Step 1: Write equation

n² - 5n + 4 = 0

Step 2: Solve for <em>n</em>

<u>Factor:</u> (n - 4)(n - 1) = 0

<u>Find roots:</u> n = 1, 4

Step 3: Check

<em>Plug in n to verify if it's a solution.</em>

1² - 5(1) + 4 = 0

1 - 5 + 4 = 0

-4 + 4 = 0

0 = 0

4² - 5(4) + 4 = 0

16 - 20 + 4 = 0

-4 + 4 = 0

0 = 0

What is the volume of a sphere with a radius of 12 units?

\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

\sf{Formula \ for \ Volume \ of \ a \ sphere \ : \bigstar\boxed{\bold{V=\displaystyle\frac{4}{3} \pi r^3}}

Where

\tt{V=Volume}\\\tt{\pi =pi}\\\tt{r=radius}

Provided Information:-

\tt{r=12\:units}

Plug in:-

\bold{V=\displaystyle\frac{4}{3} \pi (12)^3}

\bold{V=\displaystyle\frac{4}{3} \pi (1,728)}

On further simplification,

\dashrightarrow\boxed{\boxed{\underline{\bold{V=2304\pi\:m^3}}}}\dashleftarrow

<h3>Good luck.</h3>
