In the endogenous growth model of Romer (1990), workers can, without costs,
shift between the production of inputs and R&D. Imagine instead that the fraction
of researchers in the economy is a fixed parameter that cannot be changed. Then,
conjecture what happens to the responsiveness of the growth rate in the economy to
the degree of substitutability among the varieties of ideas, φ.

Uber has a monopoly on ride-sharing services. In one town, the demand curve on weekdays is given by the following equation: P = 50 - Q. However, during weekend nights, or peak hours, the demand for rides increases dramatically and the new demand curve is P = 100 - Q. Assume that marginal cost is zero.
a. Determine the profit-maximizing price during weekdays and during peak hours. [4]
b. Determine the profit-maximizing price during weekdays and during peak hours if MC = 10 instead of zero. [4]
c. Draw a graph showing the demand, marginal revenue, and marginal cost curves during peak hours from part (b), indicating the profit-maximizing price and quantity. Determine Uber’s profit and the deadweight loss during peak hours, and show them on the graph. [8]
Explain what human resource management. Briefly discuss and illustrate three important trends influencing human resource management.
I would like to know the volume of ammonium hydroxide required to add to an aqueous mixture of sulphuric acid and acetic acid to bring the pH up to 5
NH4OH(aq)+ CH3COOH (aq) = CH3COONH4(aq) + H2O(l)
2NH4OH(aq) + H2SO4(aq) -> 2(NH4)+SO4(aq)2- + 2H2O (l)
Sulphuric acid molarity: 0.08 mol/L - 6597 mols total - 1.07 pH
Acetic acid molarity: 0.09 mol/L - 7176 mols total - 2.89 pH
5. Two shafts 30 in. apart, each carrying a four-step pulley, are to be connected by a cross belt. The driving shaft is to turn 180 rpm while the driven shaft is to turn 50, 150, 250, and 600 rpm. The smallest step of the driver is 10 in. in diameter. Find (a) the diameters of all the steps, (b) angle of contact for each pair of pulleys, and (c) belt length. PLEASE EXPLAIN THE DEATILED ANSWER WITH SOLUTION.
