5. A radioactive substance decays at a rate proportional to the amount of remaining substance. Build a differential equation, identify the steady state and its stability. Now consider that Samarium 151 has a half life of 90 years, how long will it take for 200g to decay to 1g? 6. The number of bacteria increases continuously at a rate proportional to its population. Build a differential equation, identify the steady state and its stability. Now consider that if the number of bacteria doubles every 4 hours, what is the function that models the population? How long will it take for the population to be 5 times the initial value? 7. Money is earing compound interest in a mutual fund. Build a differential equation, identify the steady state and its stability. Now consider that it takes 1 year for the fund to grow by 8%. How long will it take the money to double?

In Windows, when you enter an IP address, the subnet mask is automatically displayed. However, when you enter an IP address starting with 192.168.x.x, a specific value appears, while for IP addresses starting with 10.10.x.x, a different value is displayed. The reason for this difference is due to the default subnet masks assigned to different ranges of IP addresses. The default subnet mask for IP addresses starting with 192.168.x.x is 255.255.255.0, while for IP addresses starting with 10.10.x.x, the default subnet mask is 255.0.0.0. This difference in subnet masks results in the different values displayed when entering these IP addresses in Windows.

Part F - Internal bending moment diagram Construct an internal bending moment diagram using the expressions for the bending moment that you developed earlier. Begin by drawing the line(s) of discontinuity. NOTE - The curve you choose from the drop-down is only a pictorial representation of a real quadratic/cubic curve. The equation of this curve is not mathematically equivalent to the correct answer. Consequently, slopes at discontinuities and intercepts with the x-axis (if any) are not accurate. NOTE 2 - Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place 2 vertical lines at the same place, it will appear correct visually because the lines overlap, but the system will mark it wrong.

Distributive Property Use the order of operations to demonstrate that the Distributive Property holds by showing that both sides of each equation are equal. a. \frac{4}{3}(\frac{2}{5} + \frac{1}{5}) = \frac{4}{3} \cdot \frac{2}{5} + \frac{4}{3} \cdot \frac{1}{5} b. \frac{4}{3}(\frac{2}{5} - \frac{1}{5}) = \frac{4}{3} \cdot \frac{2}{5} - \frac{4}{3} \cdot \frac{1}{5}
