During halftime at the Cavs game, a slingshot launches T-shirts at the
crowd. A t-shirt is launched with an initial upward velocity of 72 ft/s.
The T-shirt is caught 35 ft above the court. The function
y = -162+72x + 5 gives the T-shirt's height y, in feet,
after x seconds
What is the starting height of the t-shirt?*

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec.
