Tech Math: Word Problems Using Linear Equations

 


Relevant Material: "Linear equations have applications in various fields, including calculating costs and distances, solving geometry and age-related problems, and modeling scenarios in business and science. For example, they are used to determine the total cost of a service with a fixed fee plus a per-minute rate, or to calculate the relationship between Celsius and Fahrenheit temperatures. 
Business and finance 
  • Cost analysis: Determining the total cost of a product or service by using a fixed fee plus a variable rate (e.g., a phone bill with a monthly fee and per-minute charge).
    • Revenue projection: Modeling revenue based on the number of units sold.Budgeting: Planning personal or business budgets.
 Physics: Calculating speed, distance, and time using the formula
distance=rate×timed i s t a n c e equals r a t e cross t i m e
.
 Calculating angles: Finding unknown angles in geometric shapes.
 Age problems: Determining people's current ages based on relationships between them..." (Google)

Technical Math: Sine Law

Image
  **  Relevant Material : "  The sine law is used in real-life applications like   navigation   to determine positions,   surveying   to map land,   astronomy   to calculate distances to stars, and   engineering   and   architecture   to design and build structures. It is also applied in fields such as physics for analyzing forces and projectile motion, and even in computer graphics.   Navigation and Surveying Navigation:  Sailors and pilots use the law of sines to determine their location and heading by triangulating their position from known reference points. Surveying:  Land surveyors use it to calculate distances and positions for mapping and to determine the height of objects like cliffs by measuring angles from different points .   Engineering and Architecture Structural design:  Architects and engineers use the law of sines to calculate angles and dimensions for building structures, ensuring...

Tech Math: System Of Equations

Image
  **  Relevant Material: " Systems of equations have numerous real-life applications, including personal finance for budgeting and loans, optimizing business operations like pricing and resource allocation, solving problems in science and engineering, and calculating travel time and distance . They are also used in nutrition to balance diets, in geometry to find unknown dimensions, and in various fields like economics and chemistry.   Business and Finance   Budgeting: Calculate how much is left after expenses, or balance income and savings goals. Cost and Demand: Determine optimal pricing for a product by creating equations that link price, demand, and other variables. Profit and Loss: Use systems to calculate profit, expenses, and revenue over time.   Chemistry: Solve "mixture problems" by mixing two or more different substances (like solutions with specific concentrations of salt or vinegar) to achieve a final mixture with desired properties. Physics: Cal...
