Q:

Engineers are analyzing the performance of windshield wiper blades. At the end of one swipe, the tip of a blade is at (βˆ’5, 7) when represented graphically. What is the sine value of this function? (2 points) negative 7 square root 74 divided by 74 negative 5 times square root of 74 over 74 7 times square root of 74 over 74 square root 74

Accepted Solution

A:
The correct answer to this question is "7 times square root of 74 over 74."


First, we need to get for the "r."r^2 = (βˆ’5)^2 + 7^2r^2 = 25 + 49r^2 = 74r = square root of 74



Then, after that, we need to formulate the equation of a sin:sin x = 7 / rsin x = 7 / sqrt(74)sin x = 7 * sqrt (74) / 74

hope this helpsss
