3. Consider a perfectly competitive firm with the following short-run total costs: SRTC = 150 + 2q². The corresponding short-run marginal cost is given by: SRMC = 4q. a. If the market price is $80, how much output will the firm produce? b. What will the firm's profits be at a price of $80? c. Find the quantity of output for which marginal cost equals average variable cost. What does this information tell you about this firm's decision about whether to shut down in the short run rather than produce a positive quantity of output?

1. Any of you who have listened to children tell stories will recognize that, unlike adults, they tend to recall stories as a sequence of actions rather than as an overall plot. Their descriptions of a movie are filled with the phrase "and then...." An experimenter with supreme patience asked 50 children to tell her about a given movie. Among other variables, she counted the number of "and then..." statements, which is the dependent variable. The data follow: 18 15 22 19 18 17 18 20 17 12 16 16 17 21 23 18 20 21 20 20 15 18 17 19 20 23 22 10 17 19 19 21 20 18 18 24 11 19 31 16 17 15 19 20 18 18 40 18 19 16 簡單翻譯:心理學家請小孩描述電影情節,並記錄他們使用「然後」的次數,50 位小孩的次數 如上。

（大一微積分） 請問這題這樣寫正確嗎？背流程寫的😅，圖一為需用到的定義 正確的話，想問紅色圈圈的1是怎麼來的？

DEFINITION Let f be a function defined on some open interval that con- tains the number a, except possibly at a itself. Then we say that the limit of f(x) as x approaches a is L, and we write lim f(x) = L x→a if for every number &> 0 there is a corresponding number 8 >0 such that | ƒ(x) − L| < ɛ if 0 < x-a <8 then

It's widely known that bees are important for our ecosystem and that they are facing increasing threats from modern agricultural practices involving pesticides. What many of us don't know, 16. (is that some industries should shoulder a bigger share of blame than they're given.) The almond industry, for instance, has quite an adverse impact on bee colonies. One potential harm to bee colonies is the stress caused by transporting them over long distances to almond orchards for the task of pollination. This transportation can be stressful for the bees, hence 17. them more vulnerable to diseases and pests. Moreover, since they're 18. having limited food sources aside from almond flowers further weakens bee colonies. Still another problem is the of honeybees to pesticides and other chemicals used in almond production. 19. 20. and One sustainable solution is to make habitats and species within almond orchards more stable. By creating various ecosystems and introducing other insects among almond trees, at least we can ensure enough food supply for bees and even lower the use of pesticides for almond trees in the long run.
