Answer: 1.5(b)+ 2.25(s) = 10.05
Step-by-step explanation:
Answer:
The Answer is -16
Step-by-step explanation:
The equation to this would be -352 / 22, which would give you 16, hope this helped!
15u + 11u - 9d - 19d = -2d
It went up 26, down 28, a net change of down 2.
To evaluate 17 int (sin^2 (x) cos^3(x))
From Trig identity. Cos^2(x) + sin^2(x) =1. Cos^2(x) = 1 - sin^2 (x)
Cos^3(x) = cosx * (1 - sin^2 (x)) = cosx - cosxsin^2x
So we have 17 int (sin^2x(cosx - cosxsin^2x))
int (sin^2x(cosx)dx - int (sin^4xcosx)dx. ----------(1)
Let u = sinx then du = cosxdx
Substituting into (1) we have
int (u^2du) - int (u^4du)
u^3/3 - u^5/5
Substitute value for u we have
(sinx)^3/3 - (sinx)^5/5
Hence we have 17 [ sin^3x/3 - sin^5x/5]
