Answer: The sale price would be $228,025.
Step-by-step explanation:
Since we have given that
Price of her house = $35000
Price of her closing = $7500
Rate of commission = 7%
So, Amount of commission would be
So, Amount of her closing becomes
\$7500+$525
=\$8025
Amount of her loan = $185000
So, Total sales price would be
$185000+$35000+$8025
=$228025
Hence, the sale price would be $228,025.

<h3>Answer:</h3>
- using y = x, the error is about 0.1812
- using y = (x -π/4 +1)/√2, the error is about 0.02620
The actual value of sin(π/3) is (√3)/2 ≈ 0.86602540.
If the sine function is approximated by y=x (no error at x = 0), then the error at x=π/3 is ...
... x -sin(x) @ x=π/3
... π/3 -(√3)/2 ≈ 0.18117215 ≈ 0.1812
You know right away this is a bad approximation, because the approximate value is π/3 ≈ 1.04719755, a value greater than 1. The range of the sine function is [-1, 1] so there will be no values greater than 1.

If the sine function is approximated by y=(x+1-π/4)/√2 (no error at x=π/4), then the error at x=π/3 is ...
... (x+1-π/4)/√2 -sin(x) @ x=π/3
... (π/12 +1)/√2 -(√3)/2 ≈ 0.026201500 ≈ 0.02620
