Celia is a potato peeler for CanCan Foods. She decides to quit her job and instead work as a seamstress at CoverUp Clothing. This would cause:
1.a movement along the production possibilities curve.
2.a movement towards a point that is outside the PPC
3.an outward shift of the production possibilities curve.
4.an inward shift of the production possibilities curve.
Consider a production possibilities curve with maize on the vertical axis and cars on the horisontal. Unusually good weather for growing maize shift:
1.neither the horisontal intercept nor the vertical intercept.
2.the horisontal intercept rightward and the vertical intercept upward.
3.the horisontal intercept rightward but does not shift the vertical intercept.
4.the vertical intercept upward but does not shift the horisontal intercept.
Prince wants to open a Hair Salon and asks his uncle Lerumo if he will lend him the money. He also indicates that he will only be able to start paying him back after five years, at which time he will then pay R35 000 at the end of every four months, for four years. Uncle Lerumo agrees, on condition that his money must earn 12,2% interest per year, compounded every four months.
The present value of Prince's debt when he starts paying back uncle Lerumo after 5 years will be
The market for drones has undergone some changes over the past two years. As a result of these changes, the equilibrium quantity of drones has increased substantially with almost no change in the equilibrium price. Which of the following is the most likely explanation for these changes? Over the past two years:
1.demand has increased and supply has decreased.
2.both supply and demand have increased.
3.both supply and demand have decreased.
4.supply has increased and demand has decreased.

Bishop argues that there are six fundamental activities that occur in some form across all
cultures (Bishop,1991). Discuss how different cultural norms and values can influence the
teaching and practice of Mathematics through these six activities.

c. exothermic
d. both b and c are correct
2.If a substance that would increase the reaction’s rate would have been added instead, what will happen to the equilibrium?
a.shift to the left
b. shift to the right
c. none of the given options
d. no shift
3.Will the equilibrium re-established after one of your groupmates added an increment in the temperature?
a. yes
b. no
c. more information required
d. none of the given options
4.What equation relates the expression of the equilibrium constant in terms of pressure and concentration?
a.ideal gas equation
b. van’t Hoff equation
c. Arrhenius equation
d. Molarity
5.If the coefficients for a reaction are all multiplied by 2, the equilibrium constant will be
a.equal to Kc x 2
b. equal to Kc over 2
c. unchanged
d. equal to Kc2
