Answer:
I learned about this but don't remember how to do this!!! Sorry
Step-by-step explanation:
Well, since a creditor is defined as "<span>a person or company to whom money is owe", that probably means they are looking for financial information, or maybe your address to keep up with you and assuring you pay back the owed money. I could be wrong though</span>
Working with the right side:
cot(<em>x</em>) + 2 tan(<em>x</em>) + tan³(<em>x</em>) = cos(<em>x</em>)/sin(<em>x</em>) + 2 sin(<em>x</em>)/cos(<em>x</em>) + sin³(<em>x</em>)/cos³(<em>x</em>)
… = (cos⁴(<em>x</em>) + 2 sin²(<em>x</em>) cos²(<em>x</em>) + sin⁴(<em>x</em>)) / (sin(<em>x</em>) cos³(<em>x</em>))
Factorize the numerator as a sum of squares:
<em>a</em>⁴ + 2 <em>a</em>² <em>b</em>² + <em>b</em>⁴ = (<em>a</em>² + <em>b</em>²)²
… = (cos²(<em>x</em>) + sin²(<em>x</em>))² / (sin(<em>x</em>) cos³(<em>x</em>))
Recall that
cos²(<em>x</em>) + sin²(<em>x</em>) = 1
… = 1 / (sin(<em>x</em>) cos³(<em>x</em>))
… = 1 / (sin(<em>x</em>) cos³(<em>x</em>)) • cos(<em>x</em>)/cos(<em>x</em>)
… = cos(<em>x</em>) / (sin(<em>x</em>) cos⁴(<em>x</em>))
… = cot(<em>x</em>) sec⁴(<em>x</em>)
(1) The train travels 4 miles per gallon.
(2) The slope of the graph is 
Explanation:
(1) The miles that train travels per gallon is given by
Dividing, we have,
Thus, the train travels 4 miles per gallon.
(2) To determine the slope, let us consider two points from the graph.
The coordinates are 
and 
Thus, substituting the coordinates in the slope formula, we get,
Simplifying, we have,
Thus, the slope of the graph is
