A grocery store scale is used to weigh a 0.25-kg bell pepper. If this displaces the spring within the scale by 4.6 cm, the spring constant must be
Apply implicit differentiation to find $\frac{dy}{dx}$ for $\sin(x - y) = x\cos(y + \frac{\pi}{4})$. Hence find the equation of the tangent line to the curve at $(\frac{\pi}{4}, \frac{\pi}{4})$.

2. A car manufacturer revised its advertising strategy to sometimes highlight the energy- saving features of its new cars. They aired some commercials that highlighted these features and some that did not. They also tracked consumers responses to each ad. The following table shows the joint distribution of the customers reactions and the theme of the ad. Customer reaction Theme of advertisement Joint probability Negative Conservation 0.05 Neutral Conservation 0.15 Positive Conservation 0.30 Negative Standard 0.15 Neutral Standard 0.15 Positive Standard 0.20 (a) [5 points] Find the marginal probability that a customer has a positive reaction to the firm's advertisements. (b) [5 points] Find the marginal probability that a customer sees a conservation themed advertisement. (c) [9 points] What would it mean to advertising managers at this firm if the reaction and theme were independent? (d) [10 points] Are reaction and theme independent? (e) [9 points] What is the probability that a customer has a positive reaction, conditional on the theme being Conservation?

Tutorial Exercise On a given day, the flow rate $F$ (in cars per hour) on a congested roadway is given by the equation below, where $v$ is the speed of traffic in miles per hour. $\frac{v}{21 + 0.04v^2}$ What speed will maximize the flow rate on the road? Step 1 To find the speed that maximizes the flow rate on the road, we differentiate $F = \frac{v}{21 + 0.06v^2}$ with respect to $v$, set it equal to zero and solve for $v$. Therefore, $\frac{dF}{dv} = \frac{21 - \Box v^2}{(21 + 0.06v^2)^2} = 0$
