796338 | Given the recurrence sequence $A_{n+1}=(4A_n +2)/(A_n+3)$ with $A_{0}<-3$, determine the behavior of the sequence $A_n$. Specifically:
1. Is it valid to deduce that $A_n$ decreases when $A_{n+1}-A_n<0$, which holds for $-3>A_n>-1$ and $A_n>2$, and that $A_n$ increases when $A_{n+1}-A_n>0$, which holds for $A_n<-3$ and $-1<A_n<2$?
2. The potential limits are $L=-1$ or $L=2$. Can we definitively say a limit exists, given that $A_n$ is not necessarily monotone and bounded for all possible values, and the sequence could oscillate between regions where it increases and decreases?
3. Is it valid to eliminate $L=-1$ as a possible limit if the sequence is increasing in its vicinity?
4. How can one rigorously prove the existence of a limit (or lack thereof) when the sequence's behavior (increasing/decreasing) depends on the interval in which $A_n$ resides, and the extent of increase/decrease is unknown, potentially leading to oscillations between intervals? | 2 | Integer | Mathematics | University | 6 | [

1078619 | Andrew runs a nightclub called "Fun1040". Given the popularity and cache of the club, he has a monopoly position in the market. Male nightclub goers have an individual demand curve of P = 22 - q, whereas female customers each have an individual demand curve of P = 16 - q. Andrew has a marginal cost per drink of MC = $2 per unit and no fixed cost. By law, Andrew is unable to charge an entrance fee. He can, however, charge different prices for men and women for their drinks (by serving men blue glasses and women customers their drinks in green glasses). If Andrew tries to maximize profit, which statement is true?
a. Andrew charges both men and women $12 per drink; this is first-degree price discrimination
b. Andrew charges men $9 per drink and women $12 per drink; this is an example of third-degree price discrimination.
c. Andrew charges men $12 per drink and women $9 per drink; this is an example of third-degree price discrimination.
d. Andrew charges men $10 per drink and women $7 per drink; this is an example of third-degree price discrimination.

1657926 | Lott Company uses a job order cost system and applies overhead to production on the basis of direct labor costs. On January 1, 2020, Job 50 was the only job in the process. The costs incurred prior to January 1 on this job were as follows: direct materials $20,000, direct labor $12,000, and manufacturing overhead $16,000. As of January 1, Job 49 had been completed at a cost of $90,000 and was part of the finished goods inventory. There was a $15,000 balance in the Raw Materials Inventory account.
During the month of January, Lott Company began production on Jobs 51 and 52 and completed Jobs 50 and 51. Jobs 49 and 50 were also sold on account during the month for $122,000 and $158,000, respectively. The following additional events occurred during the month.
1. Purchased additional raw materials of $90,000 on the account.
2. Incurred factory labor costs of $70,000. Of this amount $16,000 is related to employer payroll taxes.
3. Incurred manufacturing overhead costs as follows: indirect materials $17,000, indirect labor $20,000, depreciation expense on equipment $12,000, and various other manufacturing overhead costs on account $16,000.
4. Assigned direct materials and direct labor to jobs as follows.
Job No. Direct Materials Direct Labor
50 $10,000 $5,000
51 39,000 25,000
52 30,000 20,000

2069073 | Dick Boe Enterprises, an all-equity firm, has a corporate beta coefficient of 1.5. The financial manager is evaluating a project with an expected return of 21 percent, before any risk adjustment. The risk-free rate is 10 percent, and the required rate of return on the market is 16 percent. The project being evaluated is riskier than Boe's average project, in terms of both beta risk and total risk. Which of the following statements is most correct?
a. The project should be accepted since its expected return (before risk adjustment) is greater than its required return.
b. The project should be rejected since its expected return (before risk adjustment) is less than its required return.
c. The accept/reject decision depends on the risk-adjustment policy of the firm. If the firm's policy were to reduce a riskier-than-average project's expected return by 1 percentage point, then the project should be accepted.
d. Riskier-than-average projects should have their expected returns increased to reflect their added riskiness. Clearly, this would make the project acceptable regardless of the amount of the adjustment.
e. Projects should be evaluated on the basis of their total risk alone. Thus, there is insufficient information in the problem to make an accept/reject decision. | c | Multiple Choice | Business | University | 6 | [

1274698 | I wish to show that $\lim_{n\to\infty}\left(1+\frac{\lambda}{n}\right)^n=e^\lambda$ as part of the proof of the Poisson limit theorem. My first avenue of attack was to take the log of both sides and then use L'Hopital's rule, but the result was of the form $0\cdot \infty$, so that didn't work. I also noticed that the proof would follow from the proof that $\left(1+\frac{1}{n}\right)^\lambda = \left(1+\frac{\lambda}{n}\right)$ for large $n$, but I wasn't able to prove this either.
