Curve before applying the theorem.)f(x, y) = y cos(x) − xy sin(x), xy + x cos(x), c is the triangle from (0, 0) to (0, 12) to (3, 0) to (0, 0)

has a clockwise orientation, so in order to use Green's theorem (which is probably the "theorem" mentioned here), we have

where is the triangle region.

c

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
