Study Notes
Mr. Kindle's Investment
- Mr. Kindle's email shows a loss of 800,againof800, a gain of 800,againof960, and another gain of $230.
- The integer representation of each gain and loss is: -800, 960, and 230
- Mr. Kindle identified an error, a “loss of 800”shouldhavebeena“gainof800” should have been a “gain of 800”shouldhavebeena“gainof800.”
- The opposite of the opposite of 800is800 is 800is800.
- The opposite of a number is its reflection across zero on a number line.
Temperature in Buffalo
- At 6:00am, the temperature was 10 degrees Fahrenheit.
- At noon. the temperature was -10 degrees Fahrenheit.
- At midnight, the temperature was -20 degrees Fahrenheit.
- -10F is greater than -20F.
- The warmest temperature was 10F.
- The absolute value of a number is its distance from zero on a number line.
- The absolute value of -10 is 10, meaning the temperature was 10 degrees below zero at noon.
Point Placement
- The point 𝑃𝑃 is located between 0 and -5 on a number line.
- The opposite of point P is point 𝐴𝐴.
- Point 𝐵𝐵 is a number less than point 𝑃𝑃.
- Point 𝐶𝐶 is a number greater than point 𝑃𝑃
- Point 𝐷𝐷 is halfway between point 𝑃𝑃 and the integer to the right of point 𝑃𝑃.
Elevation in New York
- Mount Marcy is the highest point in New York State, 5,343 feet above sea level.
- Lake Erie is 210 feet below sea level.
- Niagara Falls, NY, is 614 feet above sea level.
- The lobby of the Empire State Building is 50 feet above sea level.
- New York State borders the Atlantic Coast, which is at sea level.
- The lowest point of Cayuga Lake is 435 feet below sea level.
- Positive integers represent locations above sea level, while negative integers represent locations below sea level.
Sea Serpent Sightings
- The last four sightings of the sea serpent were at points 𝐴𝐴 (−9, 2), 𝐵𝐵(−3, −4.75), 𝐶𝐶(9, 2), and 𝐷𝐷(8, −2.5).
- Quadrant III is defined as the quadrant where both the x-coordinate and y-coordinate are negative.
- The distance between point 𝐴𝐴 and the point 9 2 , 0 is 9.
- Point 𝐸𝐸 is located at (8, 2.5).
- Point 𝐹𝐹 is located at (8, -2.5).
- The distance between points 𝐸𝐸 and 𝐹𝐹 is 5, as their x-coordinates are the same, and their y-coordinates are opposite.
