A rectangular lot whose perimeter is $440 feet is fenced along three sides.An expensive fencing along the lot\'s lenght costs $16 per foot,and an inexpensive fencing along the two side widths costs only $11 per foot. The total cost of the fencing along the three sides comes to $4060. What are the lot\'s dimensions? Solution let W is the width lan L is the length of rectangle , then .............................................................................................................................................. 2*(W + L) = 440 ................................(1) ........................................... now according to given condition ,since the only one longer side is fenced and 2 shorter lengths are fenced , so total cost function will be given by ................................................................................................................................................................ 16 *L + 11 *2*W = 4060 ...................(2).............................................. solving above equations for W and L , we have ,W =90 foot and L = 130 foot . .

Create a polynomial function that meets the following conditions. Explain how you created your polynomial. 4. Degree 3, 2 positive real zeros, 1 negative real zero, 0 complex zeros. Polynomial: Solution Polynomial may be : f(x) = -x^3 + x^2 + x - 1 Reasoning : the number of positive roots of the polynomial is either equal to the number of sign differences between consecutive nonzero coefficients. so here has two sign change(the sequence of pairs of successive signs is -+, ++, +-). So it has 2 positive roots. for negative root we change the signs of the coefficients of the terms with odd exponents, i.e., apply Descartes\' rule of signs to the polynomial f(-x), to obtain a second polynomial f(-x) = x^3 + x^2 - x - 1 it has 1 sign change so f(-x) has one positive root so f(x) has 1 negative root. .

Create a function called findChar that will return the index of where a particular character is found within a CString. Your function should take as parameters the CString to search through and a character variable to search for. The function will return the index of where the character was first found. If the array does not have the character in it, your function should return -1. NOTE: Do not convert or cast the characters to int\'s to do the searching. At this point you should be able to traverse a CString. Solution import java.util.Scanner; import java.io.*; import java.lang.*; public class FindingIndex{ public static void main(String args[]){ String [] Cstring = new String [10]; System.out.println(\"Please enter the string \"); System.out.println(\"Character to search\"); Scanner in = new Scanner(System.in); Cstring = in.nextLine(); char c = in.nextChar(); CstringIndex(Cstring,c); } public static int CstringIndex(String[] Cstring2,char newchar){ for(int i=0;i<Cstring2.length();i++) { if(c == Cstring2[i]) { System.out.println(\"Index of the character \"+i); break; } else { System.out.println(\"-1\"); } } } } .

Could someone help me with this Linux system program. Using C language. Write your own simple client/server set of processes. The client should use a shared memory segment to send a command message to the server. The server process should monitor the shared memory segment, and respond as follows: \"HI\" -- The server prints \"Greetings\" to the screen. \"PID\" -- The server prints it\'s process id to the screen. \"QUIT\" -- The server terminates gracefully, detaching and releasing the shared memory segment. Sample run: Client : Server: HI PID QUIT Solution #include #include #include #include #include #include #include #include #include #include int main(int argc, char *argv[]) { int listenfd = 0, connfd = 0; struct sockaddr_in serv_addr; char sendBuff[1025]; time_t ticks; listenfd = socket(AF_INET, SOCK_STREAM, 0); memset(&serv_addr, \'0\', sizeof(serv_addr)); memset(sendBuff, \'0\', sizeof(sendBuff)); serv_addr.sin_family = AF_INET; serv_addr.sin_addr.s_addr = htonl(INADDR_ANY); serv_addr.sin_port = htons(5000); bind(listenfd, (struct sockaddr*)&serv_addr, sizeof(serv_addr)); listen(listenfd, 10); while(1) { connfd = accept(listenfd, (struct sockaddr*)NULL, NULL); ticks = time(NULL); snprintf(sendBuff, sizeof(sendBuff), \"%.24s\ \ \", ctime(&ticks)); write(connfd, sendBuff, strlen(sendBuff)); close(connfd); sleep(1); } } .

Contrast the argument that terrorist acts are easy to predict with the argument that they cannot be identified or predicted. Write it 4-5 paragraph with resources(References). Solution By using technology it was easy to predict the terrorist acts. This is because terrorists use social media sites for communication and now-a-days there are many pattern recognization and data mining algorithms are implemented to identify the words and to predict the next action of the terrorists reference:http://www.iflscience.com/technology/how-technology-help-predict-terrorist-attacks/ And even though advancement of technology cannot predict the terrorist act all the time, because if the terrorists are at one place then they don\'t use the internet or social media sites, so there will be no chance of prediction. But NSA, which have access to almost every device in the world can easily predict the action of every human being in the world and there are many other security agencies like NSA also can do this thing. Majorly, technology plays an important role in identifying or predicting the action of terrorists .

contemporary financial management What are the differences between the primary and secondary markets? Solution The difference between the primary capital market and the secondary capital market is that in the primary market, investors buy securities directly from the company issuing them, while in the secondary market, investors trade securities among themselves, and the company with the security being traded does not participate in the transaction. .

Constants Part A By measurement you determine that sound waves are spreading out equally in all directions from a point source and that the intensity is 2.7x10-2 W/m2 at a distance of 4.5 Im from the source What is the intensity at a distance of 3.5 m from the source? Express your answer using two significant figures W/m2 Submit Incorrect. Try Again; 6 attempts remaining Part B How much sound energy does the source emit in one hour if its power output remains constant? Express your answer using two significant figures Submit Solution Part A. Intensity is given by: I = P/A = P/(4*pi*r^2) Since Source is same at both distance, So Power is constant, which means intensity is inversely proportional to square of distance from source. I2/I1 = (r1/r2)^2 I2 = I1*(r1/r2)^2 I2 = 2.7*10^-2*(4.5/3.5)^2 I2 = 4.5*10^-2 W/m^2 Part B. Power of source will be P = I*4*pi*r^2 P = 2.7*10^-2*4*pi*4.5^2 P = 6.87 W Now energy is given by: E = Power*time E = P*t t = 1 hr = 3600 sec E = 6.87*3600 E = 24732 J = 2.5*10^4 J Please Upvote. .
