Assignment 10.1 Use the following information to answer the next three exercises. A vacation resort rents SCUBA equipment to certified divers. The resort charges an up-front fee of \( \$ 25 \) and another fee of \( \$ 12.50 \) an hour. 1. What are the dependent and independent variables? 2. Write the equation that expresses the total fee in terms of the number of hours the equipment is rented. 3. Graph the equation from \#2 in Desmos and sketch it below. Use the following information to answer the next two exercises. A credit card company charges \( \$ 10 \) when a payment is late, and \( \$ 5 \) a day each day the payment remains unpaid. 4. Write the equation that expresses the total fee in terms of the number of days the payment is late. 5. Graph the equation from \#4 in Desmos and sketch it below. 6. Is the equation \( y=10+5 x-3 x^{2} \) linear? Why or why not? 7. Which of the following equations are linear? a. \( y=6 x+8 \) b. \( y+7=3 x \) c. \( y-x=8 x^{2} \) d. \( 4 y=8 \)

A car travels at a constant speed over a road that contains a series of equally spaced bumps. The spacing between bumps is d. The mass of the car is m, and the spring constant of the car's suspension springs is k. Because of resonance, a particularly jarring ride results. Ignoring the effect of the car's shock absorbers, which is the correct expression for the car's speed v in terms of d, m, and k, as well as some numerical constants? 0โ‚ O V= V= d 2ฯ€ d 2A m k m 100-4โˆš โˆš/=/ U= m

5. Part 5: Zener diode voltage regulator using the mains supply 1. Build the circuit shown in Fig. 1-2 below using a BZX85C4V7 Zener diode (For Diode simulations in QUCS use 1N4732 to replace BZX85C of part 5 and LM140-5V to replace 7805 of part 6), and four 1N4004 diodes for the rectifier. The primary of the transformer is to be connected to the mains supply (220V, 50Hz) and deliver at the secondary a voltage of about 10V peak at 50Hz (the lower the voltage, the better). 2. Use for this power supply $R_s$=620 ?, $R_B$=1 M? and C=100 ยตF (a smaller capacitor may be also used). 3. Use an Oscilloscope to visualize the $V_{out}$ waveform. 4. Change the secondary voltage to several values (0 to 15 V) and note the output Voltage. 5. Discuss the changes observed at the output compared to part 4.
