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.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to
