Given :
An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away.
To Find :
The airplane’s angle of decent.
Solution :
Height of plane, h = 2600 m.
Horizontal distance of airplane from vertices is, d = 56 km = 56000 m.
Let, angle of depression is Ф.
So,
Therefore, the angle of decent is 87.34°.
Hence, this is the required solution.
Answer:
Step-by-step explanation:
We are given the following:
and
a). Recall that a level curve of a function f(x,y) is given by where c is a constant. That is, all the points in the set of interest to which the function applied to the points is exactly the value c.
Consider c = 80. So we get
which implies that (Graph 1).
We can also consider c=60, which gives us
which implies that . (Graph 2)
b)Recall that the gradient of a function f(x,y) is given by
In this case,
Thus, the gradient of T is given by
