The series converges if x is in (Enter your answer using interval notation.) Within the interval of convergence, find the sum of the series as a function of x. If x is in the interval of convergence, then the series converges to: Find the series obtained by differentiating the original series term by term. The new series is n=0[infinity](Since this sum starts at n=0, be sure that your terms are of the form c nx nso as to avoid terms including negative exponents.)

The solvent front is 10.0 cm from the starting point and an organic solvent was used in this paper chromatography. Sketch the paper chromatography and compare the polarity of X and Y. Nick consumes chocolate over two periods. He has 20 chocolate bars which can be consumed in either period. He cannot buy more chocolate bars and left over chocolate bars do not gain or lose value. Let c 1be the amount of chocolate bars consumed in period 1 and let c 2be the amount of chocolate bars consumed in period 2. Unfortunately for Nick, there is a .25 probability that someone will steal his chocolate before he ever gets a chance to eat it. Ian the insurance broker offers to replace any stolen chocolate as long as Nick pays Ian F upfront for the insurance. Nick's utility is U(c 1;c 2;F )=c 1c 2F where c 1and c 2are the actual amounts of chocolate consumed and F is the amount spent on insurance ( 0 if no insurance is purchased, F if insurance is purchased). Nick maximizes his expected utility. Find the threshold price F for insurance where Nick is indifferent over buying insurance. What happens if F>F ? What happens if F? A force sensor was designed using a cantilever load cell and four active strain gauges. Show that the bridge output voltage (eor) when the strain gauges are connected in a full- bridge configuration will be four times greater than the bridge output voltage (e02) when connected in a quarter bridge configuration (Assumptions can be made as required). The times per week a student uses a lab computer are normally distributed, with a mean of 6.2 hours and a standard deviation of 0.9 hour. A student is randomly selected. (a) Find the probability that the student uses a lab computer less than 4 hours per week. (b) Find the probability that the student uses a lab computer between 5 and 7 hours per week. (c) Find the probability that the student uses a lab computer more than 8 hours per week.

Evaluate The Following 010x0xyxdzdydx In Example 2.8, we examined the effect of a 20-percent decline in copper demand on the price of copper, using the inear supply and demand curves developed in Section 2.6. Suppose the long-run price elasticity of copper demand were 0.75 instead of 0.50. Assuming, as before, that the equilibrium price and quantity are P =$3 per pound and Q =18 million metric tons per year, derive the linear demand curve consistent with the smaller elasticity. With a long-run price elasticity of 0.75, the linear demand curve is A. Q=31.504.50P. B. Q=31.50+4.50P. C. Q=34.504.50P. D. Q=34.50+5.50P. E. Q=31.505.50 If Mike can make 2 surfboards per hour or 10 bikes per hour and Joe can produce 4 surfboards per hour and 12 bikes.
