The next three are; 250, 1,250, and 6,250
= is parallel lines because they are in line with each other. Hope I helped :D

Answer:
A. 
Step-by-step explanation:
A. The problems asked for 2 ways to solve it, expanding the equation with the substitution x(t)=2 cos(t) and y(t)=4 sin(t) to differentiate it . The other way is by chain rule.
Expanding and differentiating:
We start by substituting x(t)=2 cos(t) and y(t)=4 sin(t) in h(x,y)=4x2+y2:

So, in the path that the hiker chose:

Chain rule:
We start differentiating h(x,y) using chain rule as follows:

Now, it´s easy to find all these derivatives:
Now we replace them in the chain rule, with the replacement x=2cos(t) and y=4sin(t) in the x,y that are left and we operate everything:




This will be our answer
