Tech Math: Word Problems

 

** 

Relevant Material: "Scientific notation is used in real life to express very large or very small numbers concisely and is applied in fields like astronomy, physics, engineering, and finance. It simplifies calculations and comparisons, for example, measuring astronomical distances, the size of atoms, or the cost of natural disasters. 
Real-world applications 
  • Astronomy: Calculating the vast distances between celestial bodies, such as the distance from the Earth to the sun (
    9.3×1079.3 cross 10 to the seventh power
    miles).
  • Physics: Describing the sizes of atoms or the mass of subatomic particles. For example, the diameter of a water molecule is approximately 
    3×10-103 cross 10 to the negative 10 power
    meters.
  • Engineering: Performing calculations with large quantities of materials or small increments in measurements. An example is the length of a kitchen, calculated by multiplying the width of a tile by the number of tiles.
  • Finance: Expressing large financial figures, such as the cost of natural disasters. For instance, the cost of Hurricane Sandy was approximately 
    6.5×10106.5 cross 10 to the tenth power
    dollars.
    • Biology and Chemistry: Representing the large number of cells in a sample or the small size of microorganisms.Computer Science: Programming languages often use a variation of scientific notation, such as "E" notation, to represent numbers.Everyday Life: Even in less formal settings, it simplifies comparisons. For example, an earthquake with a magnitude of 6 is ten times greater than one with a magnitude of 5..." (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...
