Se deja caer un ladrillo desde la azotea de un edificio. El ladrillo choca contra el piso en 2.5 segundos. Se puede despreciar la resistencia del aire, asi que el ladrillo esta en caida libre. a)¿que altura en m tiene el edificio? b)¿que magnitud tiene la velocidad del ladrillo justo antes de llegar al suelo?

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

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.

what do you mean by "representation"? graph? table? etc.
