A poor economy is at its steady state equilibrium. It is given a foreign aid package, to help it catch up with the developed world. Is this a good policy decision and why or why not?

As the production function remains the same, the economy has a temporary increase in output, but reverts back to its original steady state as the extra capital depreciates over time. This can be illustrated ...

A student titrated a solution of 25 cm3 of NaOH of concentration 0.1 mol/dm3 with H2SO4. She achieved four results; 25.8 cm3, 26.15 cm3, 26.25 cm3 and 26.45 cm3. Calculate the concentration of H2SO4 using concordant titres.

H 2 SO 4 + 2NaOH → Na 2 SO 4 + 2H 2 O Concordant titres: 26.15 cm 3 and 26.25 cm 3 Mean titre: (26.15+26.25)/2= 26.2 cm 3 /1000= 0.0262 dm 3 moles of NaOH: (25/1000)*0.1= 0.0025 mol Ratio of H 2 SO 4 : NaOH=...

Consider the curve y=x/(x+4)^0.5. (i) Show that the derivative of the curve is given by dy/dx= (x+8)/2(x+4)^3/2 and (ii) hence find the coordinates of the intersection between the left vertical asymptote and the line tangent to the curve at the origin.

The unsimplified form of the derivative can be obtained fairly easily with use of the quotient rule. The trick for simplification is to multiply top and bottom by (x+4)^0.5, this allows manipulation of the n...
