mathematicaCopy codeLine 100, 100  
Line 200, 200  
Arc 150, 150, 50  
Circle 300, 300, 100

Answer:
A line from point (100, 100) to (200, 200), followed by an arc centered at (150, 150) with a radius of 50, and a circle centered at (300, 300) with a radius of 100.

(d) Explain three ways in which Geographic Information Systems (GIS) could be used in the execution of rescue missions.
Answer:

  1. Mapping and monitoring affected areas in real-time.
  2. Coordinating the deployment of rescue teams based on spatial data.
  3. Analyzing terrain to determine the most efficient routes for rescue operations.

  1. Stock trading
  2. Smart cars
  3. Customer service
    Answer:

  • Stock on 31/12/2021: Ksh 2,589,000

Determine the cost of sales for the year for Temina Traders.
Answer:
Cost of Sales = Opening Stock + Purchases – Purchases Returns – Closing Stock
= 1,800,000 + 2,327,500 – 234,000 – 2,589,000
= Ksh 1,304,500
