I need help with this, I can figure it out until c), I did not know what or how to use that function also, e) asks for depreciation rate, which is hard to find, even if I find one is not going to be constant through out the years. Chapter 5: Depreciation of a New Car YEAR(t) VALUE(A) 0 53,330 1 2 3 4 5 (a) independent variable and value (A) as the dependent variable. (b) Find the exponential function of best fit. rt (c) Express this function in the form A = A e 0 (d) What is the value of A ? Compare this value to the purchase price of the vehicle. (e) What is the value of r,the depreciation rate? (f) Compare your value of r to others in your class. Which car has the lowest rate of depreciation? The highest? (g) new car purchase?

(a) Define propagation time $t_{PHL}$ for falling logic transitions, making clear how it differs from fall time. (b) A PMOS logic NOR gate uses a passive pull-down resistor of value 10k$\Omega$ and drives a load capacitance of 8pF. Estimate the propagation time $t_{PHL}$. (c) A single npn bipolar junction transistor with a passive pull-up is used as a logic invertor driving a stray capacitance load of 12pF. The supply voltage and the logic HIGH input voltage ($V_{IH}$) are both +5.0V. The input voltage is applied to one end of a 47k$\Omega$ resistor; the other end of the resistor is connected to the base terminal of the transistor. The transistor has a current gain ($\beta$ or $h_{FE}$) of 30 and its base-emitter junction has turn-on voltage $V_{on}$ = 0.7V. Estimate the propagation time $t_{PHL}$.
