Across
- 1. a specified amount in or for every hundred. (ex. 40%)
- 4. the trigonometric function that is equal to the ratio of the side adjacent to an acute angle to the hypotenuse.(formula. adjacent / hypotenuse).
- 5. a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point. (formula. opposite / adjacent).
- 6. the ratio of each term of a geometric progression to the term preceding it. (ex. 1, 2, 4, 8, 16, 32, 64).
- 7. Opposite or reverse (ex. x - 1, = 1/x)
- 12. the relationship in quantity, amount, or size between two or more things (ex. 1:5)
- 15. formed when two lines intersect each other at a single point. (ex.A pair of scissors)
- 17. any real number that cannot be expressed as the quotient of two integers (ex.√2)
- 18. a list of numbers with a definite pattern. (ex.3, 5, 7, 9).
- 20. form of writing a given mathematical concept like an equation, number, or an expression (Ax +By = C)
- 21. the trigonometric function that is equal to the ratio of the side opposite a given angle to the hypotenuse. (formula. opposite / hypotenuse).
Down
- 2. the difference between two consecutive terms of an arithmetic progression. (ex.4,7,10,13 add 3 each time).
- 3. the equation of a straight line.(ex.form y — y1 = m(x — x1)).
- 8. an equality that remains true even if you change all the variables that are used in that equality. (ex. x +y ) 2= x 2 + 2)
- 9. a numerical quantity that is not a whole number. (ex. 1/2)
- 10. the steepness of the line, also commonly known as rise over run (y2-y1 / x2-x1)
- 11. a number without fractions an integer.(ex.1, 2, 3, 4, 5)
- 13. arrange in a particular order.(ex.1, 3, 5, 7, 9).
- 14. All positive numbers (ex. 1,2,3,4)
- 16. figures that are the same shape, but not necessarily the same size. (ex. all circles).
- 19. a symbol and placeholder for a quantity that may change, or any mathematical object.(ex.4x,x is variable).
