A lamina with density (x; y) = 10y (x 2 + y 2 ), occupies the region inside the circle x 2 + y 2 = 2x and outside the circle x 2 +y 2 = 1, inside the Örst octant. Find the mass of the lamina. (a) Set us the integral, in rectangular (cartesian) coordinates, of the mass of this lamina. Do not integrate. (b) Set up the integral from (a) in terms of polar coordinates. Do not integrate. (c) Integrate the easier of (a) and (b)

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
