36 square miles because you take 82,080 and divide by 2,160

Solve the equation: <img src="https://tex.z-dn.net/?f=5%5Ex%5E%28%5Ex%5E-%5E1%5E%29%3D1" id="TexFormula1" title="5^x^(^x^-^1^)=1

The concept:

We are given the equation:

$5^{x(x-1)} = 1$

Which can be simplified as:

$5^{x^{2} - x} = 1^{1}$

Since any number to the power '0' is 1

x² - x must be equal to 0 for the given equation to be true

Solving for x:

x² - x = 0

x(x-1) = 0

now, we can divide both sides by either x OR x-1

So we will see what we get for either choice:

x = 0/(x-1) x-1 = 0/x

x = 0 x = 1

Hence, the value of x is either 0 or 1

Write a polynomial function in standard form for the given set of roots.

Rashid [163]

Answer:

$f(x) = {x}^{4} +4 {x}^{3} + 3 {x}^{2}$

Step-by-step explanation:

Let f(x) be the polynomial.

If x=-3, x=0,x=0, x=1 are roots ,then by the factor theorem, x+3=0,x=0,x=0, x+1=0 are factors of f(x).

This implies that:

$f(x) = (x + 3)(x)(x)(x + 1)$

$f(x) = {x}^{2} ( {x}^{2} + x + + 3x + 3)$

$f(x) = {x}^{2} ( {x}^{2} +4x + 3)$

Expand further to get:

$f(x) = {x}^{4} +4 {x}^{3} + 3 {x}^{2}$
