An astronaut on the moon throws a baseball upward. the astronaut is 6ft, 6in. tall, and the initial velocity of the ball is 30 ft per second. the height s of the ball in feet is given by the equation s= -2.7^2 + 30t + 6.5, where t is the number of seconds after the ball was thrown. after how many seconds is the ball 14ft above the moon’s surface?

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
