(8) In case Exhibit 9, Panel A, the company provides a reconciliation of the $5.66 EPS figure to the income statement’s reported EPS figure of $8.78. Also referred to as “Core EPS” in a PepsiCo-related press release, this figure, $5.66, is a non-GAAP financial measure many companies choose to report. What does a non-GAAP financial measure mean? What does the terminology “core” suggest to you? What is the reason that many companies provide non-GAAP financial information in their financial reports?

What is the Ka for a weak acid, HA, if a .2 M HA solution has a pH of 4.0?

Children playing in a playground on the flat roof of a city school lose their ball to the parking lot below. One of the teachers kicks the ball back up to the children as shown in the figure below. The playground is 4.80 m above the parking lot, and the school building's vertical wall is h = 6.30 m high, forming a 1.50 m high railing around the playground. The ball is launched at an angle of θ = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) A man on the ground kicking a ball to children on a flat rooftop is shown. The distance between the man and the building is labeled d. The height of the building is labeled h. The motion of the ball is depicted as a parabola originating from the man on the ground and ending at the rooftop. The vector of the initial motion of the ball makes an angle θ with the horizontal. (a) Find the speed (in m/s) at which the ball was launched. 18.12698 Correct: Your answer is correct. m/s (b) Find the vertical distance (in m) by which the ball clears the wall. 1.833 Correct: Your answer is correct. m (c) Find the horizontal distance (in m) from the wall to the point on the roof where the ball lands. 4.06 Correct: Your answer is correct. m (d) What If? If the teacher always launches the ball with the speed found in part (a), what is the minimum angle (in degrees above the horizontal) at which he can launch the ball and still clear the playground railing? (Hint: You may need to use the trigonometric identity sec2(θ) = 1 + tan2(θ).) 37.45 Incorrect: Your answer is incorrect. What is the final x-position? The final y-position? How much time does it take the ball to travel to the final x-position in terms of the angle? Using this result in the equation for the final y-position, you should be able to write a quadratic equation for tangent of the angle. Be sure to use the trigonometric identity in the hint. ° above the horizontal (e) What would be the horizontal distance (in m) from the wall to the point on the roof where the ball lands in this case?

In the Solow growth model with diminishing marginal returns to capital, explain what happens when the savings rate increases.

C++ Programming in Linux

The program will read the five grades from the keyboard, calculate the median, and then then display it. In addition, the program will calculate the average of the five grades and display it as well. Your program should ask the user to input the five grades and then return the median and average. Continue until the user quits.

a. Pretty Good Privacy (PGP) is broadly used to secure email communication. Explain the steps needed prior to exchanging email messages with privacy and authenticity guarantees for a pair of users using PGP.

b. Estimate the time required to crack a 56-bit DES key by a brute-force attack using a 3000 MIPS (million instructions per second) computer, assuming that the inner loop for a brute-force attack program involves around 15 instructions per key value, plus the time to encrypt an 8-byte plaintext. Perform the same calculation fora 128-bit IDEA key.

Extrapolate your calculations to obtain the cracking time fora 300,000 MIPS parallel processor (or an Internet consortium with similar processing power).
