1. [-/5 Points] DETAILS SCALC7 15.1.001.MI.SA. MY NOTES PRACTICE ANOTHER This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Estimate the volume of the solid that lies below the surface z = xy and above the following rectangle. R = ( x , y ) 1 5 5 x 5 11 , 3 sys7 ) Exercise (a) Use a Riemann sum with m = 3, n = 2, and take the sample point to be the upper right corner of each square. Part 1 of 4 We are requested to use m = 3 and n = 2 over the rectangle R = (x, y)15 s x s 11, 3 s y s 7, The subrectangles are, therefore, as follows. 4 a Assume: a = 7 b = 5 b C = 7 d = 9 e = 11 Xa Assume: a = b = 5 b d = 9 e = 11 X (5,3) C d e We can estimate the volume of the given solid using the Riemann sum EX f( xi y; )AA, with f( x, y ) = xy. i = 1j = 1 Since 5
