In an amusement park ride, a rider suspended by cables swings back
and forth from a tower. The maximum speed v (in
meters per second) of the rider can be approximated
by v = V2gh, where h is the height (in meters) at the
top of each swing and g is the acceleration due to
gravity (g = 9.8 m/sec?). Determine the height at the
top of the swing of a rider whose maximum speed is
15 meters per second.

Need on this geometry question. explain how you did it.

Barney & noblet customers can choose to purchase a membership for $25 per year members receive 10% off all store purchases 1. how much would a member pay per year if he bought $50 worth of items each year? 2. write a slope-intercept equation that expresses how much a member pays per year using x to represent his purchases per year 3. how much would a member have to spend per year to pay off his membership fee?

The table below shows the approximate height of an object x seconds after the object was dropped. the function h(x)= -16x^2 +100 models the data in the table. for which value of x would this model make it the least sense to use? a. -2.75 b. 0.25 c. 1.75 d. 2.25
