Aball is kicked from a height of 3 feet above the ground. the height of the ball, h(t), is given by h(t) = -5t^2 + 14t + 3, where *t* is the time in second after the ball is kicked. how long will it take the ball to hit the ground after it is kicked? a) 3.0 seconds b) 3.4 seconds c) 0.2 second d) -0.2 second

check the picture below.

so the ball hits the ground when y = 0, namely h(t) = 0.

we can't use the -1/5 because, the seconds after 0, can't be negative.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
