PRABG4QG write an equation that gives the amount of snow that has fallen after x hours at this rate.

Element x decays radioactively with a half life of 8 minutes. if there are 450 grams of element x, how long, to the nearest tenth of a minute, would it take the element to decay to 37 grams?

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!
