Hypotenuse² = perpendicular² + base²
H² = 20²+21²
H²= 400+441 = 841
H = √841
H = 29 cm
Answer:
-1
Step-by-step explanation:
slope = y2-y1/x2-x1
(5,5) (7,3)
slope = 5-3/5-7 = 2/-2 = -1
Answer:
45x
Step-by-step explanation:
Just expand and coolect to get 9x5=45 and add x
Answer:
Greatest Common Factor: integer or variable multiplied by other integers or variables that creat a resultin product. factor x factor = product
difference of squares binomial: an expression where two perfect square terms are being subtracteda² - b² = (a+b)(a-b)quadratic: from "quad" meaning square, because the variable gets squared (like x2).
discriminant: tells you about the roots of a quadratic
general form: y = a(x - h)^2 + kstandard form: ax^2 + bx + c = 0root: a solution of an equation
zero: a value that gives you 0 for a function
x-intercept: where the graph crosses the x-axis
y-intercept: where the graph crosses the y-axis
extraneous: a solution that does not work
parabola: the graph of a quadratic
vertex: the turning point of the parabola
axis: line of reflection
translation: movement up/down and left/right of any parabola from standard position (f(x) = x2)
