Answer: c is perpendicular to y = -5x - 2
Explanation: The slope of a perpendicular line is an opposite reciprocal of the original slope/line. (Basically switch the numerator and denominator and the sign. In this case, the slope is -5/1x. It’s opposite reciprocal is 1/5x.) 
You can take a look at my notes for further clarification. Hope this helps! 
        
             
        
        
        
Answer:
The sprinkler can spread water 18 feet away.
Step-by-step explanation:
We are given the following in the question:
Area formed by watering pattern = 1,017.36 square feet
We have to find the how far the sprinkler spread the water.
The sprinkler covers a circular area. We need to find the radius of this circular area to find the how far the sprinkler spread the water.
Area of circle = 

where r is the radius of the circle.
Putting values, we get,

Thus, the sprinkler can spread water 18 feet away.

Answer:
-2
Step-by-step explanation:
9+n/4= -15
cross multiply
9+4-15=n
13-15=n
n=-2
