a swimming pool had a list price of $575.25 and was on sale for 10% off.Sara had a coupon for an extra $75 off. What will her cost be before tax?
Answer:
First take 10% off of $575.25. 10% of $575.25 is $57.53, so 10% off would be $575.25-$57.53, which makes the price $517.72. Then, including the $75 coupon, reduces the price down to $442.72. Therefore, her price before tax is $442.72.
θ=−7π/6
The rectangular form of the polar equation is:
Mathematical formulations known as polar equations show the connections between locations in a polar coordinate system. In a polar coordinate system, a point's distance from the origin serves as its definition.
To convert a polar equation into a rectangular form, we can use the following formulas:
In this case, the polar equation is .
Using the conversion formulas, we can substitute the value of θ into these equations:
Evaluate the trigonometric functions and .
Substituting these values back into the equations:

the answer is y= 0.5774xstep by step explanation
Answer:
m+n=140
Step-by-step explanation:
While it may seem you need to find the measure of m and n, you don't. Looking at the angle with measure of 40 degrees you can see inside the triangle that the top angle is congruent to the angle of 40 degrees. Now that you know that the top of the angle is 40 degrees then knowing a triangle is 180 degrees total you can infer that m+n=140 because adding 140 to 40 is also 180.
