Avortex that rotates at constant angular velocity about the z-axis has velocity vector field ⃗ =−⃗ +⃗ ). (a) sketch, on a separate sheet of paper, the vector field with =1 and the vector field with =−1. then determine the speed ‖⃗ ‖ of the vortex as a function of the distance from its center, ) compute div v and curl v. div v = curl v=(c) compute the circulation of v counterclockwise about the circle of radius r in the xy-plane, centered at the origin. circulation =

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
