A ball is thrown from a height of 123 feet with an initial downward velocity of 11 ft/s. The balls height h (in feet) after t seconds is giving by the following h= 123 -11t-16t2

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

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.

your answer is  

a.
