Evaluate the iterated integral. 2π 0 y 0 x 9 cos (x + y + z) dz dx dy 0 Step 1 We start with the innermost integral. When integrating with respect to z, the other variables x and y are considered constants, and so x 9 cos (x + y + z) dz 0 = 9 $$sin(x+y+z) x 0 = 9 $$sin(2x+y)−sin(x+y) .

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
