Snow Creek in Colorado plans to pump between 1120 and 1200 gallons of water per minute, at least 12 hr per day between mid-October and late December. Determine the minimum amount of water is pumped per day. A projectile is launched straight up from ground level with an initial velocity of 96 ft per sec. Its height in feet, s, after t seconds is given by the equation s=-16t% +96t. At what time (s) will it reach a height of 80 ft. | will use the equation 80 = -16t2+96t to find when does it reach that height. After doing so, | found out that at t1=1 (going up) seconds it will reach 80 feet height and at t;= seconds it will be at that same height when coming down. D Question 24 5 pts x2 - 49 = (x+7) 1.
