Across
- 6. the distance between two points is found by this formula. given two points (x1,y1) and (x2,y2).
- 11. when there are more than one variables being multiplied together and raised to a power. tells us that we can simplify by multiplying the exponents and keeping the same base
- 12. given two endpoints (x1,y2) and (x2,y2). finds the halfway point between these two endpoints.
- 13. sequence in which the difference between any two terms is constant. used an our daily lifes to find the amount of people in a building,and find your yearly income.
- 15. symbol for a quantity that may change. may represent a number, a vector, a matrix, a function,, a set, or an element of a set.
- 19. when 3 or more numbers are added or multipliedthe result remains the same even if the numbers are grouped in a different way. grouping is done with parentheses
- 20. mirror image of the shape. An image will reflect through a line.
Down
- 1. The prime factors of a positive integer are the prime numbers that divide that integer exactly. it only has two numbers that can divide into it evenly which are 1 and itself.
- 2. of powers states that if a base raised to a power is being raised to another power. the exponents are multiplied and the base remains the same.
- 3. all the positive integers from 1 till infinity. Sometimes you can include 0 aswell
- 4. calculated by finding the ratio of the "vertical change" to the "horizontal change" between two points on a line. Sometimes the ratio is expressed as rise over run
- 5. longest side of a right triangle. can be found using the hypotenuse theorem
- 7. a set of numbers with a particular pattern. Each number is called a term. {3,5,7,9}
- 8. the multiplication inverse of the base, raised to the power which is opposite to the given power. must become positive before an equation can be simplified.
- 9. can use this to check if given sides form a right triangle. a and b are legs and c must be the hypotenuse. a^2+b^2=c^2
- 10. any number multiplied by 1 keeps its identity. the number stays the same is because multiplying by 1 means we have 1 copy of the number.
- 14. any number raised to a power of zero equals one except zero. Indicates there’s no factors of a number
- 16. a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression
- 17. indicates how many times one number contains another. The trick for this term is to always multiply or divide the numbers by the same value.
- 18. distribute the outer term to the inner terms, combine like terms. Arrange terms so variables are on the opposite sides. Solve the equation.
