Function would be f(x) = 5x+85
here, x= 15
5(15)+85 = 75+85 = $160
Answer:
Let's call the side of square b x. Therefore, the side of square a is 0.5x, making its area 0.25x² and the area of square b is x². This means that the percentage is 25%.
The conversion is


So

We're given the fairly unusual

It's fairly unusual because usually an angle is given in degrees or radians, and typically the radians are a fraction times pi. We'll assume radians.

Ah, there's our .75. The approximate answer is

Third choice.
The exact answer is

also a line through the origin.
The given lengths cannot form a triangle. They do not meet the requirements of the triangle inequality.
17 + 25 < 43
The triangle inequality requires each side be shorter than the sum of the other two.
