Answer:
$563.24
Step-by-step explanation:
The monthly payment on a mortgage loan is found using the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where A is the monthly payment on a loan of P at interest rate r for t years.
Filling in the given values, we find the payment to be ...
A = $70,000×(0.09/12)/(1 -(1 +0.09/12)^(-12·30)) ≈ $563.236
The monthly payment is about $563.24.

Many graphing calculators and all spreadsheets have functions that will do this calculation for you.
The angles that share the same tangent value as of tan 45 degrees would be in Quadrant III. This is because in this quadrant the ratios would equal a positive value, which is the same as in the first quadrant, also positive. Tan 45 = 1.
We would need both the x and the y values be either both positive or negative to get a positive final value.
