A Kid in King Arthur’s Court is directed by Michael Gottlieb. The main character in the film is a teenager called Calvin Fuller. Calvin is played by Thomas Ian Nicholas. This film is a modern retelling of Mark Twain’s classic book Connecticut Yankee.
Calvin lives in California, USA. He is a very shy boy and he is not very good at sports. At the beginning of the film, Calvin is playing baseball when there is a terrible earthquake. A hole opens in the ground and Calvin falls through it. He lands in the past, in the time of King Arthur.
Calvin meets King Arthur and Merlin, the wizard. King Arthur is played by Joss Ackland and Merlin is played by Ron Moody. They think that Calvin is amazing because he plays them modern music on his CD player and he shows them how to make rollerblades and a mountain bike. Calvin is trained to be a knight and he becomes more confident. Calvin helps King Arthur to beat his enemy, Lord Belasco, and then Merlin sends Calvin back to the future. Calvin finds himself back in the baseball game, but this time he wins the game.
The special effects in A Kid in King Arthur’s Court are very good. Michael Gottlieb is a great director and the actors’ performances are good. The film is funny and exciting. It’s a comedy, a drama, and an action film all in one.
Gọi số gói mà ông vịt Scrooge mua của McVees và Jays là \(x,y.\) Điều kiện: \(x,y\) là số tự nhiên. Nếu số người ở hội nghị là \(N\) thì ta có phương trình \(6x+5y=N.\)
a) Nếu ông vịt phải mua cho 58 người, ông chỉ cần mua của McVees 3 gói và của Jays là 8 gói. Khi đó \(6x+5y=6\times3+5\times8=58.\)
b) Bài toán yêu cầu chúng ta xác định số nguyên \(N\) lớn nhất mà ông vịt keo kiệt bắt buộc phải mua thừa ra một số gói Bim bim, nếu muốn đảm bảo mỗi người trong hội nghị phải được ăn đúng 1 gói Bim bim.
Đầu tiên ta nhận xét rằng nếu số người \(N\) chia hết cho 5 thì ông Vịt của chúng ta không cần phải phí phạm tiền của mình, vì khi đó ông ấy chỉ việc mua của bạn Jays \(\frac{N}{5}\) gói, còn không mua của McVees.
Khi \(N=20\) ông Vịt cần mua \(\frac{N}{5}=4\) gói của Jays, không mua của McVees. Nếu \(N=21\) ông chỉ cần giảm số gói mua của Jays đi 1 và tăng số gói của mua của McVees lên 1, tức là mua của McVees 1 gói và của Jays 4 gói. Khi đó số bim bim mua là \(6\times1+5\times3=21=N.\) Tương tự cho \(N=22,23,24.\) VÌ khi \(N\ge20,N\vdots5\) thì số gói mua của Jays là \(\frac{N}{5}\ge4\to\) bằng cách trên, khi \(N\) tăng thêm 1 thì số gói mua của Jays giảm đi 1 và số gói mua của McVees tăng thêm 1. \(N\) sẽ tăng cho đến khi \(N+5\) ta lại gặp một số chia hết cho 5 và có thể lặp lại điều trên.
Cuối cùng khi \(N=19\) thì phương trình \(6x+5y=19\) không có nghiệm tự nhiên, thực vậy \(6x\le19\to x\le3\to x=0,1,2,3\). Tuy nhiên \(19\) chia cho \(5\) dư \(4\) nên cả \(4\) trường hợp này đều không thoả mãn. (hoặc thử trực tiếp).
Vậy số \(N\) lớn nhất là \(19.\) Khi \(N>19\) thì ông Vịt sẽ tiết kiệm được tiền của mình khi mà không cần phải mua thừa ra số gói Bim-bim.
