Answer:

No

Step-by-step explanation:

If the lines are perpendicular then they will be the negative reciprocals of each other.

Calculate the slope using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)

m_{PQ} = \frac{-12+10}{-5+8} = - \frac{2}{3}

Repeat the process with

(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)

m_{RS} = \frac{-5+6}{17-9} = \frac{1}{8}

The slopes are not the negative reciprocal of each other, thus they are not perpendicular.

Mathew is watching a car race on TV. His favorite car covered 10 laps of 3.6 miles each in 18 minutes. What is average speed of
Karo-lina-s [1.5K]
In the given question, all the necessary information's are already provided. Using these information's it is easy to find the average speed of the car in miles per hour. It is given that the car covers 10 laps in 18 minutes and each lap is 3.6 miles in length.
Total distance covered by the car = (10 * 3.6) miles
                                                     = 36 miles
Now we have to convert the time from minutes to hours. So
18 minutes = 18/60 hours
                   = 3/10 hours
Now we can easily calculate the average speed of the favorite car of Mathew.
Average Speed = 36 * (10/3) miles/hour
                           = 120 miles/ hour
