Melissa is writing a class called Cell. Which method has she set up to return a double? public class Cell
{
private int chromosomes, rna;
public double time, h2o;
private static int cellCount = 0;
private static double mCount = 4.0;

public Cell()
{
chromosomes = 23;
rna = 1;
h20 = 2.0;

cellCount++;
System. out. println(“There are now ” + cellCount + “ cells”);
}

A. public Cell(int a_chromosomes, int a_rna, double a_h20)
{
chromosomes = a_chromosomes;
rna = a_rna;
h20 = a_h20;
}

B. public int getChromosomes()
{
if (chromosomes < 1) {
throw new IllegalArgumentException(“chromosom es is less than 1”);
}
return chromosomes;
}

C. public double get_mCount()
{
return mCount;
}

Corey set up his presentation for delivery to his team.the information he had to convey was critical to their job performance.he knew he would need a lot of time to explain each point

If your accelerator suddenly gets stuck what should you do

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
