Business and Economics 25. Consumer Demand When the price of an essential commodity rises rapidly, consumption drops slowly at first. If the price continues to rise, however, a "tipping" point may be reached, at which consumption takes a sudden substantial drop. Suppose the accompanying graph shows the consumption of gasoline, $G(t)$, in millions of gallons, in a certain area. We assume that the price is rising rapidly. Here $t$ is the time in months after the price began rising. a. Sketch a graph of the rate of change in consumption as a function of time. $G(t)$ (12, 3) (16, 2) (16, 1.5) $t$ 3:5-138 Full Alternative Text b. When does the "tipping" point occur? What is the instantaneous rate of change in consumption of gas at that point?

47-53 Use a graph of the sequence to decide whether the sequence is convergent or divergent. If the sequence is convergent, guess the value of the limit from the graph and then prove your guess. (See the margin note on page 680 for advice on graphing sequences.) 47. $a_n = 1 + (-2/e)^n$ 48. $a_n = \sqrt{n} \sin(\pi/\sqrt{n})$

Answer: $f$ is decreasing on (c) Find all critical points of $f(x)$. Answer: critical points: $x = $ Instructions: For parts (a) and (b), give your answer as an interval or a union of intervals, such as $(-\infty, 8]$ or $(1,5) \cup (7,10)$. For part (c), enter your $x$-values as a comma-separated list, or \textit{none} if there are no critical points.

Recall what makes practicing most productive. Which of the following describes a person employing these elements of practice efficiency? Group of answer choices: 1. Trumpeter Kelly decides to spend the first 10 minutes of practice focusing on tonguing exercises; when he detects a mistake, he plays that part again at a slower tempo, then repeats it, gradually speeding it up. 2. Clarinetist Laura spends all her practice time working on the most difficult piece of music for her upcoming recital; she gets a full day's practice done in one 4-hour sitting. 3. Guitarist Mike plays through the songs that he loves the most, spending extra time on the ones that are easiest for him to play. 4. Percussionist Chris practices a brand new xylophone exercise (recently assigned by his teacher) by playing it start-to-finish 15 times without stopping for any reason.
