The price of bronze has increased by 10% per year from 2000. in the year 2000, harry bought a bronze medal for $120. which of the following functions f(x) can be used to represent the price of the medal x years after 2000? f(x) = 120(0.9)x f(x) = 10(120)x f(x) = 120(1.1)x f(x) = 10(1.1)x

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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.
