The height of a ball thrown directly up with a velocity of 10 feet per second from a initial height of of 100 feet is given by the equation h(t)=-16t^2+10t+100 where t is the time in seconds and h is the ball’s height, measured in feet. when will the ball hit the ground? round your answer to the nearest tenth. a. 1.4 seconds b. 2.8 seconds c. 3.1 seconds d. 3.7 seconds

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
