Graph the function f(x) = x*e^( − 5/x − 2/x^2)
Pay attention to the following (show your work!):
• asymptotic behaviour at ±∞ and behaviour at 0.
• compute the derivative and find the critical points, including limx→0 f ‘(x).
• compute points of inflection and the sign of f 00 on each interval.
Would like to know how to solve this for future reference.

Hi I need help with my homework! This is basic high school problems that should take less than 15 minutes. Please show all your steps (for the graphing ones you need to graph by hand by manipulating the function).
Graph Problem Use the graph to answer questions below.
1.If the above graph is a depiction of the state of the economy as it is now, is the economy in a recession or inflation? _____________________________(Recesion / Inflation ?)
2. Given the state of the economy shown in the above graph, what fiscal policies could the Government use to combat the problems in the economy?
3. If the government went ahead and implemented these policies;
– What would happen to prices? _____________
– What would happen to employment?______________
– What would happen to the government budget?______________
1. Great Britain has a great literary tradition that spans centuries. One might assume, then, that Britons read more than citizens of other countries. Some Canadians, however, feel that a higher percentage of Canadians than Britons read. A recent Gallop poll reported that 86% of 1004 randomly sampled Canadians read at least one book in the past year, compared to 81% of 1009 randomly sampled Britons. Do these results indicate that the percentage of Britons who read at least one book in the past year is less than the percentage of Canadians who read at least one book in the past year?
a) What are the null and alternative hypotheses for this situation? Write the hypotheses in proper statistical notation.
b) What conditions must be met to use a Normal approximation for this situation (name them)?
c) Explain how the conditions have been met to use a Normal approximation. Show calculations, where necessary.
d) What is the standard deviation for this distribution? Show your formulas and work!
e) Neatly draw or copy the distribution from StatKey.
f) What is the p-value for this sample? Indicate the p-value on the graph above.
g) What is the formal conclusion regarding the hypothesis?
h) What is the conclusion in CONTEXT in a complete sentence?
Grear Tire Company has produced a new tire with an estimated mean lifetime mileage of 36,500 miles.
Grear Tire Company has produced a new tire with an estimated mean lifetime mileage of 36,500 miles. Management also believes that the standard deviation is 5,000 miles and
that tire mileage is normally distributed. To promote the new tire, Grear has offered to refund some money if the tire fails to reach 30,000 miles before the tire needs to be replaced. Specifically, for tires with a lifetime below 30,000 miles, Grear will refund a customer $1 per 100 miles short of 30,000.
a) For each tire sold, what is the expected cost of the promotion?
b) Please perform the simulation for 1000 times, what is the probability that Grear will refund more than $50 for a tire?
How do I set this up with Excel and run simulation?
Gravity on Another PlanetAfter landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 46.0 cm. The explorer finds that the pendulum completes 101.0 full swing cycles in a time of 134 s.
Gravity causes objects to be attracted to one another. This attraction keeps our feet firmly planted on the ground and causes the moon to orbit the earth. The force of gravitational attraction is represented by the equation,where is the magnitude of the gravitational attraction on either body, and are the masses of the bodies, is the distance between them, and is the gravitational constant. In SI units, the units or force are , the units of mass are , and the units of distance are . For this equation to have consistent units, the units of must be which of the following?
