QUESTION 1: Due to the demands of high-speed internet connectivity at Ipine Island, a telecommunication company Waiezuddin Laju Sdn. Bhd. wishes to run fibre optic cable from point A on the shoreline as shown in FIGURE 1 to an installation at point B on the island. The island is X km from the shore. The costs are RM 700,000 per km to run the cable on land and RM 900,000 per km underwater respectively. Assume that the cable starts at point A and runs along the shoreline, then angles at D and runs underwater to B (Ipine Island). As a Computing Scientist at the Waiezuddin Laju Sdn. Bhd., you are given the task to find the point D at which the line begins to angle to yield the minimum total cost. How much is the cost? The following assumptions can be made: 11 ≤ x ≤ 12, and 7 ≤ y ≤ 8. B (Ipine Island) Y km с FIGURE X km D Shoreline A
