College Calculus - Vector fields, Work, and Circulation section. In the following exercises, find the work done by force field F on an object moving along the indicated path.

65. F (x, y) = - xi - 2yj

Where C is the unit circle centred at the origin with counterclockwise orientation. Note: If the initial point and ending point are the same we call this CIRCULATION.​

Abiologist is recording the loss of fish in a pond. he notes the number of fish, f, in the pond on june 1. on july 1 there were 63 fish in the pond, which is 52 fewer fish than were in the pond on june 1. which equation represents this situation? a. f – 52 = 63 b. f – 63 = 52 c. 63 – f = 52 d. f – 63 = –52

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

On a piece of paper graft y+2> -3x-3 then determine which answer matches the graph you drew
