Laboratory 11B: Methyl Orange

1) What changes to the synthetic sequence used for methyl orange would need to be made to generate FD&C Orange #1 (see lab manual for the structure). (Some structure drawings will be helpful when answering this question).

2) Some fabrics stained strongly with methyl orange while others stained poorly. Using one of the strongly stained fabrics as an example, explain what features of that material result in it being strongly stained.

3) Explain why methyl orange changes color at different pH.

In one or two paragraphs, please discuss how Fed Reserve’s interest rate policy will influence Stock and Bond markets.

Write a PHP script that checks a word or a phrase (stored in a string variable) to determine if it is a standard palindrome, a perfect palindrome, or not a palindrome at all. Also, for each letter that the word/phrase contains, count and print the number of times that each consonant and vowel is encountered. Your output will look as follows:

Word/phrase: racecar

Perfect palindrome

Contains consonants:

r - 2

c - 2

Contains vowels:

a - 2

e - 1

Willowbrook School

Chapter 12

Willowbrook School is a small private school that has retained your services as a systems analyst

to assist in the development of a new information system for the school’s administrative needs.

Background

After implementation of a new system, it moves into the support phase of the SDLC. The system

at Willowbrook has been up and running for five months now, and things are moving reasonably

smoothly. Willowbrook is pleased with the system’s ability to

handle registration and some

of the school’s other administrative and financial tasks.

You have been asked to contract

for ongoing support services on an as needed basis. The school would like to arrange for support

services in such a way that your time is used as efficiently as possible because their budget for

support is small.

Tasks

4.

You decide to prepare a security checklist for Willowbrook. Prepare a list of security

issues that the firm should evaluate and monitor. Be sure to organize the items into

categories that match the six security levels

Question 4 [10]
Discuss the potential merits of housing subsidies granted by government to poor households and
evaluate their economic impact using a diagram.

The following information is available from the accounting records of DeWitt Engineering Ltd. for the year ended June 30, 2021:

Instructions
Prepare a combined Statement of Income and Comprehensive Income for the year ended June 30, 2021. The company has a 30% income tax rate and records gains and losses on equity investments as other comprehensive income.

1. A muon and an antimuon are moving in opposite directions with velocities of -0.6 c and 0.6 c, respectively. When they collide, they can annihilate each other and turn into two photons. Both muon and antimuon have a mass of 105.66 MeV/c2. What is the total energy before the collision?

2. What is the energy of each photon?

3. What is the wavelength of each photon?

Write a C++ program that solves a quadratic equation to find its roots. The roots of a quadratic equation ax2 + bx + c = 0 (where a is not zero) are given by the formula (–b ± sqrt(b2 – 4ac)) / 2a *Use #include for the use of sqrt. The value of the discriminant (b2 – 4ac) determines the nature of roots. If the value of the discriminant is zero, then the equation has a single real root. If the value of the discriminant is positive then the equation has two real roots. If the value of the discriminant is negative, then the equation has two complex roots. The program takes values of a, b, and c as input and outputs the roots. Be creative in how you output complex roots. Include a loop that allows the user to repeat this calculation for new input values until the user says she or he wants to end the program.

9..Consider the following data for a one-factor economy. All portfolios are well diversified.

Portfolio                 E(r)              Beta

A                           12%               1.2

F                             6%                0.0

Suppose that another protfolio E is well diversified with a beta of 0.6 and expected return of 7%.

Complete the function, MycountWords in C++, which will count the number of words in a string. We will have different word separators(such as newline(\n), spaces, special symbols(? | \ , . : ;) ) That will separate the words in the giving istringstream. Remember if a words is separated by a hyphen and followed by a new line, they're still one word. The function has an option to be sensitive to case and also avoid duplicates. for duplicates, this is a boolean value that checks whether a word is repeated or not if its set to true and sensitive case is if the word count is sensitive to case and differentiates two words based on their case. even though they have different cases, they are the same word hence duplicates.

complete this function based on the description above.

unsigned int MycountWords(istringstream & iss, bool Duplicate=false, bool SenstiveCase =false) {

}
