2t^3 [6] 2. For times $t \ge 0$, a certain temperature is given by the function $T(t) = \frac{2t^3}{e^{0.4t}}$, where $t$ is in minutes and $T$ is in $^\circ C$. Before answering the questions below, use a graphing utility (desmos.com is good) to graph this temperature function for $t \ge 0$. Think about how the graph of $dT/dt$ should look. Display the graphs of $T(t)$ and $dT/dt$ together and see how accurate your thoughts were. a) Use calculus and hand-calculations to find an exact expression for the maximum temperature that is reached (your answer will involve $e$). b) If this temperature is ever (at any instant) rising or falling at a rate greater than 4$^\circ$C/min, then there is risk of equipment damage. Use your graphing utility to find the time intervals during which there is risk of equipment damage. (no work to show here; just give the intervals)

Dillon Corp. authorized $190,000 of 6% (cash payable each December 31), 10-year bonds on January 1 of Year 1. The bonds are callable at any point after Year 5 at 103. The bonds sold on January 1 of Year 1 at 98. Straight-line amortization of bond discounts and premiums is used. Due to a drop in interest rates, Dillon decided to call in half of the bonds and issue a new series of bonds at par in the amount of $95,000 (5% cash interest annually, five-year term) on January 1 of Year 6. a. Provide the entry for issuance of the 6% bonds on January 1 of Year 1. b. Provide the entry for issuance of the 5% bonds on January 1 of Year 6. c. Provide the entry for redemption of one-half of the 6% bonds on January 1 of Year 6. a. Jan. 1, Year 1 Account Name Dr. Cr. To record the issuance of bonds. b. Jan. 1, Year 6 Account Name Dr. Cr. To record the issuance of bonds. c. Jan. 1, Year 6 Account Name Dr. Cr. To record the redemption of bonds.

3) Derive an expression for the load current in the voltage to current converter that we built in lab. Check quantitatively the agreement with your measured results [similar to how you did this for (2)]. 4) Find the output voltage for the circuit below. If we connect a 4 $k\Omega$ resistor to the load, use the node rule to determine the current at the output of the op amp (magnitude and direction).
