Answer:
Step-by-step explanation:
The change of distance over time of the plain A is 300 mi/hour and 200 mi/hour for plane B. O is the point of the airport.
So, the distance from A to O AO = 90 miles and BO = 120 miles.
Now, we have a right triangle here. We can use the Pythagorean theorem, so the distance between the planes will be:
(1)
If we take the derivative of the equation (1) we could find the change of the distance between planes.
Finally,
I hope it helps you!
find the slope of the line given:
y = mx+b
y = -3x/2 -7/2
slope = -3/2
the slope of the perpendicular line is the negative reciprocal
so answer is 2/3

Answer:
.
Step-by-step explanation:
We want to find the value of .
Note that;
This implies that;
Also 270 degrees is a quadrantal angle.
On the unit circle, is the x-coordinate of the point
Hence, .
