Sketch the region enclosed by the curves: $y=8-x^2$, $y=x^2, x=0, x=3$ and observe that the region between them consists of two separate parts. Find the area of this region.

The moment of inertia of the disk about $O$ is $22 \mathrm{~kg}-\mathrm{m}^2$. At $t=0$, the stationary disk is subjected to a constant $50 \mathrm{~N}-\mathrm{m}$ torque. (a) Determine the angular impulse exerted on the disk from $t=0$ to $t=5 \mathrm{~s}$. (b) What is the disk's angular velocity at $t=5 \mathrm{~s}$ ?

A test of null hypothesis against alternative hypothesis, where the null hypothesis states that the mean is 0 while for alternative hypothesis states that the mean is not equal to 0 has test statistic of z = 1.876. Is this test statistically significant at the 5% level ($\alpha$= 0.05)?ls it statistically significant at the 1% level ($\alpha$ = 0.01) ?
