The U.S. government reports the rate of inflation (as measured by the Consumer Price Index) both monthly and annually. Suppose that for a particular month, the monthly rate of inflation is reported as \(0.8 \%\). Assuming that this rate remains constant, what is the corresponding annual rate of inflation? Is the annual rate 12 times the monthly rate? Explain.
Use the shell method to find the volume of the following solids. The solid formed when a hole of radius 3 is drilled symmetrically along the axis of a right circular cone of radius 6 and height 9.
A spring has a restoring force given by \(F(x)=25 x .\) Let \(W(x)\) be the work required to stretch the spring from its equilibrium position \((x=0)\) to a variable distance \(x\). Find and graph the work function. Compare the work required to stretch the spring \(x\) units from equilibrium to the work required to compress the spring \(x\) units from equilibrium.
When records were first kept \((t=0),\) the population of a rural town was 250 people. During the following years, the population grew at a rate of \(P^{\prime}(t)=30(1+\sqrt{t}),\) where \(t\) is measured in years. a. What is the population after 20 years? b. Find the population \(P(t)\) at any time \(t \geq 0\)
Which curve has the greater length on the interval \([-1,1], y=1-x^{2}\) or \(y=\cos (\pi x / 2) ?\)
