Consider the vector field f = (y-x, x) and curve c: r(t) = (5cos t, 5sin 0 for 0 lessthanorequalto t lessthanorequalto2 pi. a. based on the picture, make a conjecture about whether the circulation of f on c is positive, negative, or zero. b. compute the circulation. a. choose the best answer below. a. the circulation is probably positive because the vector field resembles a clockwise rotation field. the circulation is probably positive because the vector field resembles a counterclockwise rotation field. the circulation is probably close to zero because the vector field is nearly symmetric across a line that passes through the center of the circle. b. the circulation is: (type an exact answer, using x as needed.)

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
