Answer:
$376,528
Explanation: You have to ÷ $4,518,336 by 12 because there is 12 months in 1 year. That equals 376,528. Therefore her average income was $376,528.
28:36, I hope this helps if it doesn't then tell me.
The excluded values of x are
and 
Explanation:
The given expression is 
The excluded values are the values in the fraction which makes the denominator equal to 0.
Thus, from the definition of excluded values, let us equate the denominator to 0.
Hence, we have,

Adding both sides of the equation by 1, we get,

Taking square root on both sides of the equation, we get,

Simplifying, we get,

Thus, the excluded values of x are
and 
By functional analysis we have the following conclusion about the function given: The domain for f(x) is all real numbers greater than or equal to 2.
<h3>How to determine the domain of a function with radical components</h3>
Domain is the set of x-values such that the value of the function exists. By algebra we know that the domain of polynomials is the set of all <em>real</em> numbers, whereas the domain of <em>radical</em> functions is the set of x-values such that y ≥ 0. If we know that f(x) = 2 · x² + 5 · √(x - 2), then the domain is restricted by the <em>radical</em> component and defined by x ≥ 2.
By functional analysis we have the following conclusion about the function given: The domain for f(x) is all real numbers greater than or equal to 2.
