A 25.0 mL sample of a 0.2200 M solution of aqueous trimethylamine is titrated with a 0.2750 M solution of HCI. Calculate the pH of the solution after 10.0, 20.0, and 30.0 mL of acid have been added; pK$_b$ of (CH$_3$)$_3$N = 4.19 at 25°C. pH after 10.0 mL of acid have been added = 9.81 pH after 20.0 mL of acid have been added = 8.90 pH after 30.0 mL of acid have been added = 1.30

North-eastern Plc Ltd. produces and sells a single product for $120, and incurs variable costs per unit totaling 45% of the sales price. North-eastern currently sells 5,700 units each month and has fixed costs of $257,000 per month. Consider each of the following separately: Part A The marketing manager thinks sales are too low in St. Kitts and Nevis and suggests that sales there would be increased by 150 units per month if an additional $6,000 per month was spent advertising there. What should be the effect on monthly income if this additional advertising is done? Answer 1 Question 30 Increase by $3,900Increase by $2,100Increase by $2,187Increase by $309,900 Part B The marketing manager believes that sales staff could sell as additional 350 units of product each month if properly motivated, and is considering cutting their collective monthly salaries by $50,000 while giving them a $7 commission on each unit sold. What effect should this strategy have on monthly income? Answer 2 Question 30 IncreaseDecrease of $Answer 3 Question 30. Part C Management believes monthly sales can be increased by 760 units if additional quality control steps are taken. These steps would mean an increased variable cost per unit of $5. What is the expected effect on the company's monthly income of adding these additional quality control steps? Answer 4 Question 30 Increase by $17,860Increase by $50,160Increase by $46,360Increase by $37,240

You measure 29 randomly selected textbooks' weights, and find they have a mean weight of 35 ounces. Assume the population standard deviation is 2.3 ounces. Based on this, construct a 99% confidence interval for the true population mean textbook weight. Give your answers as decimals, to two places <\mu<

In 1925, scientists exploring how lipids are arranged within cell membranes performed a key experiment using red blood cells. Using benzene, they extracted the lipids from a purified sample of red blood cells. Because these cells have no nucleus and no internal membranes, any lipids they obtained were guaranteed to come from the plasma membrane alone. The extracted lipids were floated on the surface of a trough filled with water, where they formed a thin film. Using a movable barrier, the researchers then pushed the lipids together until the lipids formed a continuous sheet only one molecule thick. The researchers then made an observation that led them to conclude that the plasma membrane is a lipid bilayer. Which of the following would have allowed the scientists to come to this conclusion? Choose one:When pushed together, the extracted lipids dissolved in water.The extracted lipids covered twice the surface area of the intact red blood cells.The extracted lipids covered the same surface area as the intact red blood cells.The extracted lipids covered half the surface area of the intact red blood cells. Interestingly, higher HER2 levels have been found on the plasma membranes of cells with rigid plasma membranes, and lower HER2 levels on the plasma membranes of cells with less rigid plasma membranes. Which of the following treatments could potentially be added to the lapatinib treatment to further reduce cancer cell growth? Choose one:A. Treat with a drug that leads to phospholipids with longer lipid tails.B. Treat with a drug to stabilize the interaction of cholesterol with phospholipids.C. Treat with a drug that leads to increased saturated lipid tails in the phospholipids.D. Treat with a drug to lower the patient’s cholesterol levels.E. Treat with a drug to increase the patient’s cholesterol levels. Interestingly, higher HER2 levels have been found on the plasma membranes of cells with rigid plasma membranes, and lower HER2 levels on the plasma membranes of cells with less rigid plasma membranes. Which of the following treatments could potentially be added to the lapatinib treatment to further reduce cancer cell growth?

Substituting this back into the limit and canceling common factors gives us the following. $f'(a) = \lim_{x \to a} \frac{x^{1/3} - a^{1/3}}{(x^{1/3} - a^{1/3})(x^{2/3} + x^{1/3}a^{1/3} + a^{2/3})} = \lim_{x \to a} \frac{1}{(x^{2/3} + x^{1/3}a^{1/3} + a^{2/3})}$
