You own two lakes rich in fish. The quantity of fish caught in each lake depends on the number of persons who fish in each, according to
Q1 = 10N1 - 0.1(N1)^2 and
Q2 = 16N2 - 0.4(N2)^2,
where N1 and N2 denote the number of fishers at each lake. In all, there are N fishers working for you, each of them is paid a wage w, and the price of fish is P.
Write down your optimization problem as an optimization problem with a single variable, N1. Hint: find N2 from the formula N = N1 + N2, and replace it in the objective function.
Write down the first order condition for this problem. Do not need to solve the equation in this step.
The first order condition (which you did not solve yet) implicitly defines the optimal number of fishers in lake 1, N1* as a function of P, w, and N. Use the implicit function theorem to calculate all three partial derivatives of N1*.
Solve the first order condition to calculate N1*.
Write down and check the second order condition(s).

Maco Inc. leased equipment to Pelican Co on January 1, 2020. The lease agreement calls for annual rental payments of $3,050 at the beginning of each year of the 3 year lease. The equipment has an economic useful life of 7 years, a fair value of $12,000, a book value of $5,000 and Maco expects a residual value of $4,000 at the end of the lease term (and 0 at the end of the assets life). Maco sets the lease payments with the intent of earning a 6 percent return. There is no bargain purchase price option, ownership does not change at the end of the lease term and the asset is not specialized in nature.
a. Assuming the residual value is not guaranteed, determine the lease type for the lessee. You must explain your answer.
b. Record the journal entry(ies) for the lessee for the first year and the subsequent leave payment on the first day of the following year. Date the journal entry(ies).
c. Record the first year of journal entries for the lessor d. How would the accounting for the lease change if the residual value is guaranteed? Both parties expect it to be $4,000.

Marge N. O’Hara, a senior analyst for a large stock brokerage has been tasked to forecast the weekly closing stock prices for this blue-chip stock for the first four weeks of next year. You are assigned to provide technical support to Ms. O’Hara. Weekly closing stock prices for all 52 weeks of this year for this blue-chip stock are reported in units of dollars ($). use mititab or excel 11. Prior to attempting ARIMA modeling, Ms. O’Hara wants to verify that differencing will make the weekly closing stock price data stationary. a. Present a time series plot of the first differences of the weekly closing prices. b. Does this plot appear to show horizontality? Explain why? c. Does this plot appear to show constant variance? (That is, overall, are the first differences of the weekly closing prices confined within a band?) Explain why? d.

Hello, I very stuck on this c++ blackjack project and was wondering if anyone can offer help and guidance on this subject
can someone help he with part 4 i have no idea how to approach the problem and how to do it
I have compeleted a few parts to this project they are listed below
Part 1 – Displaying Cards Write a function to display (print) a card. sample program output void displayCard(int card) Prints the name of the card (ten of spades, queen of diamonds etc.). The parameter should be a value between 1 and 13, from which the type of card can be determined (1 = ace, 2 = two, …, 10, == ten, 11 = jack, 12 = queen, 13 = king). The card suit (clubs, diamonds, hearts or spades) should be determined randomly.
Part 2 – Generating Cards Write a function to get a card. int getCard() Returns a random value between 1 and 13, representing a card (ace, 2, …, queen, king). You do not have to keep track of which cards are dealt. So, if the game deals the queen of spades five times in row that is perfectly acceptable.
Part 3 – Determining a Cards Score Write a function to return a card's score. int cardScore(int card) Returns a value between 2 and 11 as described in the rules. Recall that the score is the card's value except that aces are worth 11 and face cards are worth 10. The card parameter represents the card for which the score is to be determined.
Part 4 – Dealing Cards Now that you've completed Parts 1 and 2 you can write a function that handles dealing cards. int deal(bool isPlayer, bool isShown) This function is responsible for: 1. Generating the next card to be dealt (Part 1) 2. Printing out what card was dealt (Part 2) and to whom, if needed (see below) 3. Returning the card's score (Part 3) The two Boolean parameters are related to printing out the card. The isPlayer parameter is used to determine whether the word PLAYER or DEALER should be printed at the start of the output. The isShown parameter is used to determine if the card should be printed – recall that the second card dealt to the dealer is hidden.
