A. Perpendicular!
Because they cross with a 90 degree angle :]
The point on the unit circle corresponding to -180 degrees is
((x, y) = (-1, 0).
<span>tan(-180°) = y/x = 0/(-1) = 0</span>
Answer:
22 feet per second
Step-by-step explanation
15x5280=79,200
79,200/60=1320 feet per minute since 60 minutes per hour
1320/60=22 feet per second since 60 seconds per minute
Hey!
------------------------------------------------
They already give us the slope, so we can solve the y-intercept.
We can use (3, -2).
y = 8x + b
-2 = 8(3) + b
-2 = 24 + b
-2 - 24 = 24 + b - 24
-26 = b
------------------------------------------------
Hence, the answer is
