Upon carrying out the procedure that was chosen in parts (a) and (b), the number from the problem statement, 626.7 x 10^(3), is expressed in the proper format c * 10^(p) where 1<=c<10 , p is an element of (...,-2,-1,0,1,2...)
Find the radius of convergence, R, of the series. ∞ xn + 98n! n = 3 Find the interval, I, of convergence of the series. (Enter your answer using interval notation.) Step 1 We will use the Ratio Test to determine the radius of convergence. We have the following. lim n → ∞ an + 1an = lim n → ∞ xn + 108(n + 1)! xn + 98n! = lim n → ∞ xn + 108(n + 1)! · 8 xn + 9

A certain reaction has an enthalpy of $\Delta H$ = -24 kJ and an activation energy of $E_a$ = 53 kJ. What is the activation energy of the reverse reaction? $E_{a(reverse)}$ = kJ
You are monitoring a patoent's pulmonary artery catheter. The pulmonary artery waveform spontaneously change to pulmonary artery wedge pressure waveform. Choose the correct intervention. 1. Inflate the ballon with 2.5 cc of air 2. Check that the ballon is fully deflated 3. Monitor the patient for crackles 4. Immediately pull the catheter back to the right atrium
A company is hiring for a new position. Applicants come from two groups, Group A and Group B. Both groups have the same average productivity, but information about individuals from Group B is less reliable and more variable. The expected cost of acquiring employees is estimated to be $75,000. • Group A: Productivity is certain ▪ Expected productivity = $100,000 • Group B: Productivity is variable ▪ 20% chance of high earner ($250,000) ▪ 80% chance of low earner ($62,500) a. If the company must choose between hiring an applicant from Group A or Group B, which should they hire? Explain your reasoning with calculations (assume the company is risk averse). b. Suppose the company can invest in more detailed information about Group B, increasing the probability of hiring a high earner to 35% and decreasing the probability of hiring a low earner to 65%. What is the maximum amount the company should be willing to pay for this information? c. Assume the cost of acquiring more detailed information about Group B is less than the maximum amount calculated in part b. Which firm is more likely to invest in the information—a competitive firm or a monopolist? Explain.
