hey guys,
i need some help with these questions. (please show some working out):
1. John borrows $28,000 to buy a house and undertake to repay it at $350 per month. Interest is compounded monthly on the balance owing at the rate of 12% per annum.
a) How much does he owe after 12 repayments?
b) Calculate the minimum number of repayments required to clear the debt.
2. A force is applied to a particle which is moving in a straight lone. Each second it moves only a half the distance of the preceding second, If the particle moves 10cm in the first second, how far will it move before coming to rest?
3. Find the values of x for which the curve y = 2x^3 - 3x^2 - 12x +6 rises with downward concavity.
thanks.
