Verify Green's Theorem for the line integral (we are going to drop the "o" for orientation on integral signs - everything we now do must be properly oriented) | r’ydx – z>y? dy JC where C consists of the parabola y = x2 – 4 from (3,5) to (-3,5) and the line segment from (3,5) to (-3,5).

7x+8y=-18, 4x-9y=-3 solve the system of equations

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities
