Quadratic variation
if f(x) varies directly with x2, and f(x) = 75 when x = 5, find the value of f(4).
a.100 b.50 c.48 d.25
find the constant of variation for the quadratic variation.
6y = 9x2 a.4/9 b.2/3 c.3/2 d.
write a quadratic variation equation if g(x) varies directly with x2, and g(x) = 108 when x = 6. a. b. c. d.

answer is because 4×10=40

and 98×4= is 392

40,392

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
