1 Express $1153.6 \times 10^3$ in standard form. flag bookmark A $1.1536 \times 10^6$ B $1.1536 \times 10^3$ C $1.1536 \times 10^{-3}$ D $1.1536 \times 10^{-6}$ $1153.6 = 1.1536 \times 10^3$, so $1153.6 \times 10^3 = 1.1536 \times 10^3 \times 10^3 = 1.1536 \times 10^6$.
2 Which of the following is **not** a requirement to apply for a credit card? flag bookmark A 21 years old and above B Remember the PIN number C Minimum income of RM24 000 per annum D Requires a salary slip or supporting documents To apply for a credit card you must be at least 21 years old, earn the minimum annual income and show salary slips or other documents. Remembering a PIN is something you do after getting the card, not a condition for applying.
3 Vinesha deposited RM4 800 in a bank with an interest rate of 3.5% per annum. Calculate the total savings of Vinesha after 3 months. flag bookmark A RM42 B RM168 C RM4 842 D RM4 968 Simple interest $I = Prt = 4800 \times 0.035 \times \frac{3}{12} = $ RM42. Total savings = RM4 800 + RM42 = RM4 842.
4 Which of the following is **not** a purpose of taxation? flag bookmark A Source of government revenue B A financial tool to stabilise the economy C Control of sales of goods or services D To increase the tourism industry T5 Chapter 4.1a The Purpose of Taxation and Types of Taxes in Malaysia Taxes are collected to provide government revenue, to help stabilise the economy and to control the sale of certain goods or services (for example, high taxes on cigarettes). Increasing tourism is not a purpose of taxation.
5 Which of the following is a correct example of a fixed expense and a variable expense? flag bookmark A Fixed: home utilities; Variable: petrol expenses B Fixed: children's needs; Variable: car instalments C Fixed: allowance for parents; Variable: insurance premium D Fixed: housing loan; Variable: groceries T4 Chapter 10.1b Evaluating Financial Status and Creating a Financial Plan A fixed expense is the same amount every month, such as a housing loan instalment. A variable expense changes from month to month, such as groceries. Car instalments and insurance premiums are fixed, so B and C are wrong; utility bills change each month, so A is wrong.
6 Diagram 1 shows the distance-time graph of a car over a period of 20 seconds. Calculate the average speed, in m s⁻¹, of the car over the 20 seconds. flag bookmark A 7.5 B 8.0 C 10.0 D 20.5 T4 Chapter 7.1b Interpreting Distance-Time Graphs The car travels 100 m out in the first 10 s, then 50 m back (from 100 m to 50 m). Total distance = 100 + 50 = 150 m. Average speed = 150 ÷ 20 = 7.5 m s⁻¹.
7 Diagram 2 shows the speed-time graph of a toy car over a period of 12 seconds. If the deceleration of the toy car is 0.5 m s⁻², calculate the value of the speed $v$, in m s⁻¹. flag bookmark A 3 B 4 C 5 D 6 T4 Chapter 7.2c Interpreting Speed-Time Graphs The speed falls from $v$ to 0 in 12 s at 0.5 m s⁻² each second: $\frac{v - 0}{12} = 0.5$, so $v = 6$ m s⁻¹.
8 Diagram 3 shows the graph of a quadratic function. Find the value of $h$. flag bookmark A −1 B −3 C −2 D −4 T4 Chapter 1.1d Axis of Symmetry of a Quadratic Function The axis of symmetry $x = -5$ is halfway between the two roots −8 and $h$: $\frac{-8 + h}{2} = -5$, so $h = -2$.
9 Given that $y$ varies directly as $x^2$ and $y = 80$ when $x = 4$, express $y$ in terms of $x$. flag bookmark A $y = x^2$ B $y = 5x^2$ C $y = \dfrac{1}{x^2}$ D $y = \dfrac{5}{x^2}$ T5 Chapter 1.1c Worked Examples: Finding the Constant and Solving Direct Variation Equations $y = kx^2$: $80 = k(16)$, so $k = 5$ and $y = 5x^2$.
10 In Diagram 4, PQ is a straight line with gradient $-\frac{3}{4}$. Find the y-intercept of the straight line PQ. flag bookmark A −3 B −12 C 3 D 12 Gradient $= -\frac{\text{y-intercept}}{\text{x-intercept}}$, so $-\frac{3}{4} = -\frac{c}{4}$ and $c = 3$.
