Answer:
y -5 = -4(x -(-1))
Step-by-step explanation:
because a perpendicular line is the negative reciprocal of the slope. the slope was 1/4, the negative reciprocal of the is -4. then plug into the equation
y-y1 = m (x-x1)
In degrees: 3π/4 radians = 135°
Angle of x=135° is in the 2nd Quadrant and has negative cos x values and positive sin x values.
cos 135° = cos ( 90° + 45°)= - sin 45° =

sin 135° = sin ( 90° + 45° ) = cos 45° =

The answer is easy
So we need to fund m2NLM
The answer is c
You know that every 10 minutes the oil moves 25 meters so and in 1 hour there are 60 minutes the equation is 60/10(25) and then you solve
The answer is 150 meters squared
