Answer:
3x²+5x
Step-by-step explanation:
Step-by-step explanation:
t = 9x, and dx = 1/9 dt.
∫ sin(9x) dx
= ∫ sin(t) (1/9 dt)
= 1/9 ∫ sin(t) dt
= -1/9 cos(t)
= -1/9 cos(9x)
Labor costs of the workers at $8 per hour working 40 hours each=$640
Revenue for the week=$2000
therefore labor cost as a percentage of revenue would be=32%
