Assume a competitive firm faces a market price of ​$100​, a cost curve​ of : C​ = 0.003q³​ + 25q ​+ 750​, and a marginal cost curve ​ of: MC​ = 0.009q² + 25. If a specific tax of ​$8 per unit is​ implemented, what would be the new equilibrium output​ level?

Metal complexes Prepare a plot of log Cd²⁺ vs P_H2S for solutions at pH 8.0 and with TOTCd = 10⁶ M, for a range of P_H2S from 10⁶ to 10³ atm. What are the concentration of the Cd-H₂S species when P_H2S is equal to 10^-5 atm?

Consider the country of Freedonia. Let i = 0.05. Groucho, a man living in Freedonia, is trying to figure out if he should take a year of extra education. If he does, Groucho can earn $40 that year(t = 1). The year after that, he can earn $220.

1. What is Groucho’s present value of future payments if he educates himself?
2. Groucho could earn $100 this year if he does not enroll in the education program. If he does enroll, he must do not have to pay any tuition immediately, but for the next year, Groucho must pay $50 per year to the program. What is the present cost of enrolling in the year-long education program?
3. Find the internal rate of return for this extra year of schooling.
4. Will Groucho end up enrolling? Why or why not?

a quadratic utility function given by 𝑈(𝑥,𝑦)= 𝑥+𝑦−0.05𝑥2−0.05𝑦2 where $90 is the consumer’s budget and the prices of the two goods are, respectively, 4 and 5. What are the optimal values of x and y to maximize the utility function of the cons

1.The Ice Chalet offers dozens of different beginning ice-skating classes. All of the class names are put into a bucket. The Monday night (ages 8 to 12) beginning ice-skating class was picked. In that class, there were 64 girls and 16 boys. Suppose that we are interested in the true proportion of girls (ages 8 to 12) in all beginning ice-skating classes at the Ice Chalet. Assume that the children in the selected class are a random sample of the population.

Do you think you are ready to become a parent? Make a short list of the qualities you possess that you think would make you a good parent. Then list those qualities that might be a hindrance to good parenting. Do you think your partner (if you have one) is ready to become a parent? Create the same type of lists based on his or her personal qualities. You can still answer the questions if you are already a parent. Just answer the questions as a reflection of sort.
