Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 13 m/s at an angle 52 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground.

1.What is the maximum height the ball goes above the ground?

2. After catchingt he ball, Sarah throws it back to Julie. The ball leaves Sarah's hand a distance of 1.5 meters above the grounf, and is moving with a speed of 10m/s when it reaches maximum height of 8m above the ground. Wat is the speed of the ball when t leaves Sarah's hand?

3.How high above the ground will the ball be when it gets to Julie?

C++ How can I print out the subtrees in my self-balancing tree? What I would like to do is have it display something like " ROOT = X, LEFT PARENT = X, X,X, RIGHT PARENT = X,X,X.

Here is my code:

#include <iostream>
using namespace std;

class TreeNode
{
public:
   int data;
   TreeNode* left;
   TreeNode* right;
};

TreeNode* newNode(int data);

/* A function that constructs Balanced
Binary Search Tree from a sorted array */
TreeNode* convertToBTS(int arr[],
   int start, int end)
{
  
   if (start > end)
       return NULL;

   //make the middle number the root
   int mid = (start + end) / 2;
   TreeNode *root = newNode(arr[mid]);

  
   root->left = convertToBTS(arr, start,
       mid - 1);

  
   root->right = convertToBTS(arr, mid + 1, end);

   return root;
}

/* Helper function that allocates a new node
with the given data and NULL left and right
pointers. */
TreeNode* newNode(int data)
{
   TreeNode* node = new TreeNode();
   node->data = data;
   node->left = NULL;
   node->right = NULL;

   return node;
}

//The array will be sorted in PreOrder
void preOrder(TreeNode* node)
{
   if (node == NULL)
       return;
   cout << node->data << " ";
   preOrder(node->left);
   preOrder(node->right);
}

int main()
{
  
   const int SIZE = 7;
   int arr[SIZE];
   int count = 7, num = 0;

   cout << "We will construct a Self-Balancing Tree!\n Enter 6 numbers for the nodes." << endl;

   for (int i = 0; i < SIZE; i++)
   {
       cout << "Enter " << count << " more items!" << endl;      
       cin >> arr[i];
       count--;
   }

   int n = sizeof(arr) / sizeof(arr[0]);

   /* Convert List to BST */
   TreeNode *root = convertToBTS(arr, 0, n - 1);
   cout << "The tree will be displayed in PreOrder!" << endl
       << "First number will be the ROOT. Then LEFT SUBTREE, and RIGHT SUBTREE." << endl;
   preOrder(root);

   return 0;
}

Describe how the Rational User Process can accommodate agile process. Specify in what phases and what disciplines agile methods could be appropriate.

You are the lead auditor performing a walkthrough of the bank reconciliation performed by the company controller. What is the design deficiency of the control below ? What additional steps should the Controller perform ?

The Controller says, "I first review the sorted list of returned checks and find which numbers are missing. Second I determine the amount uncleared checks by referring to the cash disbursements journal. If the bank accounts reconcile at that point, the review is done. If it does not reconcile I search for in transit deposits, checks from the beginning outstanding checks list that still have not cleared, other reconciling items and bank errors until it reconciles."

5. In recent years, about twenty states have passed so-called medical marijuana laws. Typically, these laws permit individuals to lawfully purchase marijuana from licensed stores, providing they have a letter from their doctor recommending its uses. In a number of these states, the price of medical marijuana is observed to be higher than that of the pot sold illegally just down the street. Use the reasoning in this chapter to explain (a) why people would be willing to pay a higher price for the medical marijuana, and (b) why it might be misleading to compare the observed price of the medical variety with the observed price of the illegal weed.

Calculate the pH of a buffer solution prepared by dissolving 4.2 g of NaHCO3 and 5.3 g of Na2CO3 in 0.20 L of water. Will the pH change if the solution volume is increased by a factor of 10?

Assume you are considering a portfolio containing two assets, L and M. Asset L will represent 39% of the dollar value of the portfolio, and asset M will account for the other 61%. The projected returns over the next six years, 2018–2023, for each of these assets are summarized in the following table. *huge thumbs up for correct answers*

Projected Return (%)

(Year)  (Asset L)  (Asset M)

(2018) (14%)  (21%)

(2019) (13%)  (19%)

(2020)  (15%)  (16%)

(2021)  (17%) (15%)

(2022)  (18%)  (11%)

(2023)  (20%)  (10%)

a.Use an Excel spreadsheet to calculate the projected portfolio return, rp, for each of the six years.

b. The average expected portfolio​ return, rp, over the 6-year period is (blank) %

c. The standard deviation of expected portfolio returns over the 6-year period is (blank) %

d. How would you characterize the correlation of returns of the two assets L and​ M? (neg. pos. or un-correlated)

e. Discuss any benefits of diversification achieved through creation of the portfolio.  

​ A. By combining these two negatively correlated​ assets, the overall portfolio risk is increased.

B. By combining these two positively correlated​ assets, the overall portfolio risk is reduced.

C. By combining these two negatively correlated​ assets, the overall portfolio risk is reduced.

D.By combining these two negatively correlated​ assets, the overall portfolio risk is eliminated.

Consider an object with a mass of 3.5 kg located at R1 = (0.0 m, 2.5 m), another object with a mass of 3.5 kg located at R2 = (1.5 m, 1.5 m), and a third object with a mass of 8.5 kg located at R3 = (– 2.5 m, 2.5 m), and a fourth object with a mass of 5.0 kg located at R4 = (2.5 m, 0.0 m). Calculate the center of mass of this group of four objects. Give your answer in the form Rcm = (xcm, ycm) and with 2 significant figures.

Block 1, with mass m₁ and speed 3.5 m/s, slides along an x axis on a frictionless floor and then undergoes a one-dimensional elastic collision with stationary block 2, with mass m₂ = 0.67m₁. The two blocks then slide into a region where the coefficient of kinetic friction is 0.57; there they stop. How far into that region do (a) block 1 and (b)block 2 slide?
