In 2015 Kraft Foods Group Inc., merged with H.J. Heinz Co. to form the world's fifth-largest food and beverage company. Heinz is a global brand, famous for its tomato ketchup, sauces, soups, beans, pasta and infant foods. Kraft is one of North America's largest consumer packaged food and beverage companies, with annual sales revenues of more than $\$ 18$ billion and over 22000 employees in the USA. Define the term merger.

Determine the values displayed by each cout statement in the following program:

#include <iostream>
using namespace std;
int firstnum = 10;  // declare and initialize a global variable
void display();     // function prototype
int main() {
    int firstnum = 20;  // declare and initialize a local variable
    cout << "\nThe value of firstnum is " << firstnum << endl;
    display();
    return 0;
}
void display(void) {
    cout << "The value of firstnum is now " << firstnum << endl;
    return;
}

(Refer to the previous exercise.) According to the IPCC, if present trends continue, future increases in average global temperatures (in ${ }^{\circ} \mathrm{F}$ ) can be modeled by

$$T(C)=6.489 \ln \frac{C}{280},$$

where $C$ is the concentration of atmospheric carbon dioxide (in ppm). $C$ can be modeled by the function defined by

$$C(x)=353(1.006)^{x-1990},$$

where $x$ is the year.

Approximate the slope of the graph of $T$. What does this slope represent?

According to an article in the Economist, historian David Faure argued that the Chinese economy failed to grow rapidly during the nineteenth century because “familyrun companies could not raise sufficient capital to exploit the large-scale opportunities tied to the rise of the steam engine, notably railways and (with limited exceptions) global shipping and automated manufacturing.” How did the United States solve the problem of firms raising enough funds to operate railroads and other largescale businesses?

Consider the initial-value problem $y^{\prime}=2 y, y(0)=1$. The analytic solution is $y=e^{2 x}$. (a) Approximate y(0.1) using one step and Euler’s method. (b) Find a bound for the local truncation error in $y_1$. (c) Compare the actual error in $y_1$ with your error bound. (d) Approximate y(0.1) using two steps and Euler’s method. (e) Verify that the global truncation error for Euler’s method is $O(h)$ by comparing the errors in parts (a) and (d).

Indicate whether each of the following statements concerning atmospheric $\text{CO}_2$ is true or false.

a. Plants remove $\text{CO}_2$ from the atmosphere via photosynthesis.

b. The absorption of visible light by $\text{CO}_2$ is a contributing factor to “global warming.”

c. Among atmospheric gases, $\text{CO}_2$ is the most effective absorber of infrared radiation.

d. Current atmospheric concentrations of $\text{CO}_2$ are approaching 200 ppm.

Global Airlines randomly chose 10 passengers from today's 9 a.m. Chicago-Tampa trip as part of their customer service programme. Each sampling traveller will be questioned on the services, amenities, and other aspects of the airport. Each passenger received a number when they boarded the aircraft in order to choose the sample. The range of numbers ranged from 001 to 250. What other way could a random sample be selected from the 250 passengers?

The Navstar Global Positioning System (GPS) utilizes a group of $24$ satellites orbiting the Earth. Using "triangulation" and signals transmitted by these satellites, the position of a receiver on the Earth can be determined to within an accuracy of a few centimeters. The satellite orbits are distributed around the Earth, allowing continuous navigational "fixes." The satellites orbit at an altitude of approximately $11,000$ nautical miles [1 nautical mile $=1.852 \mathrm{~km}=6076 \mathrm{ft}$ ] (a) Determine the speed of each satellite.

Write an essay of your own in response to Bacon's reflections on studies. or in . response to one of the axioms in the Primary Source on page no.$7$.Your response to Bacon may drainage from total disagreement total approval of all he says. In your opening statement,tell what the topic of your essay wiil be. Be sure to bringing examples and experiences from real life to support or refute Bacon. Give your essay a titles that uses the word Of.

Acid rain, rainwater that has a lower-than-normal pH, can have a severe negative impact on the plant and animal life in a region. What are the main components of acid rain? Research the sources of these components and what steps are currently in place to improve the pH of rainwater. Explain why acid rain is considered a regional problem, whereas ozone depletion is considered a global problem. What negative effects of acid rain are observed in your town or region?

According to Global Research News (Mar. 4, 2014), one-fourth of all rough diamonds produced in the world are blood diamonds. (Any diamond that is mined in a war zone - often by children - in order to finance a warlord's activity, an insurgency, or an invading army's effort is considered a blood diamond.) Also, 90% of the world's rough diamonds are processed in Surat, India, and of these diamonds, one-third are blood diamonds. Find the probability that a rough diamond is not a blood diamond.

Salma is at the top of a cliff looking down at Rico’s boat. They both have Global Positioning System (GPS) devices and are communicating via cell phones. They determine that Rico’s boat is 5.0 km from a point on the shore directly below Salma, and 6.0 km from Salma herself. a) Draw a diagram to represent this situation and label the given information. b) Find the angle of depression at which Salma is viewing Rico’s boat. c) Find the height of the cliff.

If all the ice on West Antarctica was melted, how much would it cause global sea level to rise? If you do not remember the approximate size of this rise, the volume of ice is $3,000,000 \mathrm{~km} 3$ and the surface area of the world's ocean is $361,000,000 \mathrm{~km} 2$.

A. less than 1 centimeter

B. 1 to 10 centimeters

C. 10 centimeters to 1 meter

D. 1 meter to 10 meters

E. more than 100 meters
