C, the graph intersects the x axis at 3 and - 3. As a factored form of your x intercepts will be (x+3)(x-3)
The answer is 492.307
The number after the thousandths is 9 - greater than 5 - so we round 6 up to 7.
I believe that A is the answer. We can solve this by multiplying 75cm, 65cm and 30cm together. This would give us 146,250.00ml. We can then divide 146,250.00 by 1000 to receive 146.25. We then divide 146.25 by 2 to calculate how many litres there are in half a tank. This would result in 73.125. After that, we multiple 73.125 by the cost of the fuel, which is R20.35. We then receive R 1,480.09375, which can be rounded to R 1,480.10
