Find the average value fave of the function f on the given interval. f(t) = e^sin(t) cos(t), [0, π/2]
RideAnS [48]

The question is related to integration and we have to used the following formula

\frac{1}{b-a}\int\limits^a_b {f(x)} \, dx

\frac{1}{\pi /2 -0}\int\limits^0_{\pi/2} {e^{sin t}cos t } \, dt

= \frac{2}{\pi}(e^{sin t})_{0}^{ \pi /2}

=\frac{2}{\pi}(e^{sin(\pi/2)} -e^{sin0})

=\frac{2}{\pi}(e -1)

The work in an office takes 150 hours to complete every week.
Eva8 [605]

Answer:  A minimum of 5 people will be needed.

Step-by-step explanation:

150/32 = 4.6875

You can't have a partial person, so round up to 5.

It may be possible to have 4 employees working 32 hours and another working 22 hours, but that is not what the question asks exactly. That is still 5 people.
