I believe the answer you are looking for is 2 angles
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
Answer:
6m
Step-by-step explanation:
If it doesn't move it's just the same force
Answer:
C because the rest are pythagoreaum theroems 1 squared plus 2 squared does not equal 3 squared.
Step-by-step explanation:
Answer: Yes its rational
when 5/15 is calculated to standard form it is 1/3. Here the denominator is not equal to 0 so it is not equal to 0
