1) A ball, A, is thrown vertically upward from a height, h, with a speed of 15 m∙s-1. AT THE SAME INSTANT, a second identical ball, B, is dropped from the same height as ball A as shown in the diagram below.
Both balls undergo free fall and eventually hit the ground.
Calculate the distance between ball A and ball B when ball A is at its maximum height.
(Acceleration due to gravity = 9,8 m·s-2 )
2) 3x + 1 ; 2x ; 3x – 7 are the first three terms of an arithmetic sequence. Calculate the value of x.
3) T@z bought a house. She paid a deposit of R102 000, which is equivalent to 12% of the selling price of the house. She obtained a loan from the bank to pay the balance of the selling price. The bank charges her interest of 9% per annum, compounded monthly. The period of the loan is 20 years and she starts repaying the loan one month after it was granted. Calculate her monthly installment.
4) Calculate the balance of her loan immediately after her 85 th installment
Once you have the answers to the 4 questions, you will need to calculate (S 26°0A.BCD ; E°0E.FG) from the below.
A= Take the answer of 1 without the numbers after the decimal and divide by 11
B= The ten value of answer 4
C= 10 thousand value of answer 4
D= The hundredth digit of answer 4
E= Answer to question 2 plus 1
F= The cents value of answer 3 subtracted from 99 cents
G= The cents value in answer 4 plus 10 cents
