The average value of a function f(x, y) over a rectangle R is defined to be fave = 1 A(R) R f(x, y) dA. Find the average value of f over the given rectangle. f(x, y) = 4x2y, R has vertices (−5, 0), (−5, 4), (5, 4), (5, 0).

answer: b i think

step-by-step explanation:

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
