An object 5 centimeters high is placed 15 cm in front of a converging lens with focal length 5 cm. Using graph paper (turn the paper so that the long side is horizontal) and a straight edge, draw appropriate rays to locate the image. Chose a scale (tell me what it is!) such that the lens is in the center of the page and the object is near the left side of the page a. Is the image real or imaginary? Explain your conclusion b. What is the height of the image? c. Where is the image located? d. What is the ratio (image height)/(object height)? e. Compare your results with those predicted by the lens equation 1/f = 1/p + 1/q

3) Assume Disney stock is trading at $100/share today but you believe its price will fall in the very near future to $80/share. If this is all you believe and assuming you want to make money, describe in great detail how you could profit from this belief. Make sure to use the correct terminology.

4) Assume you buy a $1,000 Par, 5% coupon, 10-year bond has when its trading at a Yield To Maturity (YTM) of 4%. If you sell it two years later (when it has a maturity of 8 years) when it’s YTM is 3.5% what is your Profit or loss in dollars, _____________________

There are three varieties of banana.

Variety A:

Number of chromosomes in a leaf cell = 22

Growth rate of fruit = 2.9

Breaking strength of leaf = 10.8

Variety B:

Number of chromosomes in a leaf cell = 33

Growth rate of fruit = 6.9

Breaking strength of leaf = 9.4

Variety C:

Number of chromosomes in a leaf cell = 44

Growth rate of fruit = 7.2

Breaking strength of leaf = 7.8

Banana growers can only grow new variety B plants by producing lateral shoots near the base of the stem. Explain using cell division how growing variety B on a large scale will affect the genetic diversity of bananas.

Respond to the following prompts in a post with a minimum of 200 word

• Since the end of the Great Recession, interest rates have been at historic lows—in some cases, close to zero. How is expansionary monetary policy, or more specifically a open market purchase, supposed to work? How do near-zero interest rates limit the ability of expansionary monetary policy to work?
• How has the Fed responded to this quandary? That is, what policies has the Fed conducted?
• In your opinion, how effective has the Fed’s policy been as a response to the Great Recession? What evidence can you suggest to support your position?

Please answer the second and third parts

Suppose the mean and the standard deviation of the waiting times of passengers at the bus station near the Cross Harbour Tunnel are 11.5 minutes and 2.2 minutes, respectively.

(a) Assume the waiting times are normally distributed. How likely a randomly selected passenger waits less than 15 minutes at the bus station?

(b) Assume the waiting times are normally distributed. 82% of the passengers at the bus station are expected to wait more than k minutes. Find k.

(c) For a random sample of 36 passengers, find the probability that their mean waiting time will be less than 11 minutes. Does your calculation require assuming the waiting times to be normally distributed? Explain.

Corporate Financial Management:Valuation of Bonds

9. a. The XYZ Company has €1,000 par value, 9% coupon bonds outstanding. The bonds will mature in 20 years. What is the current price of the bonds if the present yield to maturity is 6%? Suppose the yield to maturity increases to 11%. What do you think will happen to the price of the bond? Explain why.

2. Explain the difference between the real rate of return and the nominal rate of return. An investment offers a 15 per cent total return over the coming year. You think the total real return on this investment will be only 9 per cent. If this turns out to be true, what will the rate of inflation over the next near be?

In the Benefits vs. Costs worksheet, you looked at how friends might exchange rewards in a relationship. This exchange might occur more easily when friends live near one another, and would occur based on the proximity-attraction principle as we choose friends from those who live close by. However, technology has changed this pattern to some extent, giving us the ability to socialize easily from great distances. List three proximal friendships and three distant friendships and describe how you stay in touch. How do you describe the benefits vs. costs in proximal vs. distant friendships based on your own interactions?

Imagine two species of snakes that live in a tropical rain forest of Malaysia do not typically interbreed. In nature, one species is ground-dwelling and feeds mainly on insects and small amphibians near water, whereas the other snake feeds in the lower to mid-canopy of trees and vines rising from the forest floor. However, at a zoo in Singapore where they were kept in the same gallery exhibit, the two species were observed interbreeding and produced viable offspring. Which of the following reproductive barriers is most likely preventing these species from interbreeding in the forest?

• habitat isolation
• gametic isolation
• reduced hybrid viability
• a postzygotic barrier
• mechanical isolation

a) A thick steel plate of total area 840 cm² (both sides) is exposed to air near the ocean. After 1 year it was found to have lost 502 g in weight due to corrosion. What is the rate corrosion, or corrosion penetration rate CPR, for the material in this environment? Density of steel = 7.9 g/cm3                               [8 marks]

b) What type of corrosion is this? [2 marks]

c) Provide two strategies (there are more than two of course, but just choose two) for dealing with this type of corrosion [2 marks]

d Briefly summarise the pros and cons of each strategy as they might apply to a children’s playground at a seaside beach front [8 marks].
