A) -64
B) 1/8
C) 1/2

Answer 1

4 + 2) − (2 + 1. 2. ) = 7. 2 . △. (b) f(x, y) = xy. 1+y2 ; R is the rectangle defined by ... 4. (2)2) − ( ln(2). 4. (−2)2). = 0. △. (c) f(x, y)=2x + 4y; R is bounded by x = 1, ... (4. 3. (3)3 + 3(3)2 + 2(3)) − (4. 3. (1)3 + 3(1)2 +2(1)). = 188. 3. ≈ 62.67. △ .... (7) Find an equation of the least squares line for the data points (1,8), (2,6), (5,6), (7,4),.

Answer 2

2x ^-4 y
=2y/x^4
=2(4) / 2^4
=8/16
=1/2

answer is C) 1/2
