Suppose that $f$ is a function given as $f(x) = 6x + 7$. We will compute the derivative of $f$ at $x = 3$ as follows. First, we will compute and simplify the expression $f(3+h)$. $f(3+h) =$ Then we compute and simplify the difference quotient between $x = 3$ and $x = 3 + h$. $\frac{f(3+h) - f(3)}{h} =$ The derivative of the function at $x = 3$ is the limit of the difference quotient as $h$ approaches zero. $f'(3) = \lim_{h \to 0} \frac{f(3+h) - f(3)}{h} = $

Which of the following statements regarding enzymes is true? Question 25 options: Enzymes change the equilibrium point of the reactions they catalyze. Enzymes make the rate of a reaction independent of substrate concentrations. Enzymes increase the rate of a reaction by reducing the rate of reverse reactions. Enzymes increase the rate of a reaction by making the reaction more exergonic. Enzymes increase the rate of a reaction by lowering the activation energy barrier.

Find the value of $L_{eq}$ in the given network.. Find $V_1$, $V_2$ and $V_3$ in the circuit shown. Assume that all the capacitors had zero charge on them before the circuit was energized. All voltages are dc voltages. Determine the phase angle that $i_1(t)$ lags $v_1(t)$ and $v_1(t)$ leads $i_2(t)$, where $v_1(t) = 37 \sin(377t - 55^\circ) V$ $i_1(t) = -25 \cos(377t + 15^\circ) A$ $i_2(t) = -35 \sin(377t + 32^\circ) A$

Problem 2 In the 1970s, gasoline was rationed in many countries. In this exercise, we will see how this affects demand. A consumer maximizes the utility function $u(G, R) = 0.05 \ln(G) + 0.95 \ln(R)$ where G is her gasoline consumption in liters and R is remaining expenditures in euros. The price of gasoline is $p_G = 1$ euro per liter (hint: work with general $p_G$ first), the price of the other expenditures are $p_R =$ 1 by definition. Income is m. a) How much gasoline will the consumer buy if she is allowed to buy at most 20 liters of gasoline? b) Now assume that the consumer can additionally buy unlimited gasoline on the black market at a price of 1.40 Euro per liter. How much gasoline will she buy on the black market? c) Plot both consumption decisions on a graph.
