1point) suppose f∫ (x, y)=⟨2y,−sin(y)⟩ and c is the circle of radius 5 centered at the origin oriented counterclockwise.
(a) find a vector parametric equation r∫ (t) for the circle c that starts at the point (5,0) and travels around the circle once counterclockwise for 0≤t≤2π. r? (t)=
(b) using your parametrization in part (a), set up an integral for calculating the circulation of f? around c. ∫cf∫∫ dr =∫baf∫ (r∫ (t))∫r∫ ′(t)dt=∫ba dt with limits of integration a= 0 and b= 1
(c) find the circulation of f? around c.
circulation =

(05.02)a farmer has decided to divide his land area in half in order to plant soy and corn. calculate the area of the entire area so he knows how much soil is needed. a parallelogram with a height of 6 yards and side length 9 yards. the height forms a triangle with the slanted side of the rhombus with a base of 2.5 yards. rhombus is split into a soy half and a corn half. each bag of soil covers 40 square yards. how many bags should the farmer purchase?
