Use green's theorem to evaluate the following line integral. assume the curve is oriented counterclockwise. the circulation line integral of f=< ()+y> where c is the boundary of {(x, y): 0< =y< =sinx, 0< =x< =pi}

The line integral you need to compute is

By Green's theorem, this is equivalent to the double integral,

where is the region with boundary . This integral is equal to

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
