Answer:
x=6,y=0
Step-by-step explanation:
2x+y=12
3x-y=18
5x=30
x=6
6(3)-y=18
18-y=18
y=0
None of the two answer choices are correct, answer is none of the above
simplify by multiplying by 2 we get 10g+6h+8. neither of the two choices match

By the fundamental theorem of calculus,

Now the arc length over an arbitrary interval

is

But before we compute the integral, first we need to make sure the integrand exists over it.

is undefined if

, so we assume

and for convenience that

. Then
Answer:
