Which of the following imaging techniques can be potentially dangerous if metal is present in the room?

True or False: If you made a mistake in a medical record, you can cover it with white it out and write the correct information over it. 

For the following reaction; 2A + 3B –> C A is a second order reactant, and B is a first order reactant. The general rate law is:  rate = kab … You can use the desmos online calculator. a) If is 0.65M and is 0.008M when the rate of the reaction is 1.4 x 10-2 M/s, solve for the rate constant for that reaction.   b) using that rate constant, solve for the rate of the reaction when is 1.4 x 10-4M and is 2.75 x 10-2M   c) for the same reaction, solve for if the rate is 1.4 x 10-3 M/s when is 0.7M

a) How can a coffee cup calorimeter be used to determine the change in enthalpy (

a n = 1 + 11 n n {“version”:”1.1″,”math”:”a_n = \frac{1+\sqrt{11n}}{n}”}Determine whether the nonincreasing sequence converges or diverges.

Please select “True.” (Question omitted.)

The slope fields f(t, y) for two IVPs y’ = f(t, y) are shown below.   (a) Trace (approximately) the solution on both figures if the initial condition is y(t = 0) = 0.1 (indicated by the star). If you are taking the quiz online, then write down the approximate values of y(t) at four different points in the domain 0 < t < 10  (b) For which one of the two problems would a method like RK4 (classical explicit 4th order Runge-Kutta) be more appropriate? Why? (c) What method would you recommend for the other problem? Why?

Consider the following approximations for the first derivative: (forward difference formula}) (center difference formula) In class, we learned how the truncation and round-off errors for the center difference formula are proportional to h2 and , respectively . Minimizing the total error, yields an optimal step size . (a) The truncation and round-off errors for the forward difference formula are proportional to h and , respectively. Minimize the total error to find the optimal step size . Hint: < . (b) Evaluate the derivative of at x = 1 using the two formulae with their respective optimal step sizes. Which formula is more more accurate? The true derivative is e.
