Awoman at the top of the cliff that is 256 feet tall drops her hairpin. the distance from the hairpin to the ground can be modeled by the equation h=-16tsquared+ s, where h is the height from the ground, t is the time in seconds, and s is the initial height from the ground in feet. how long will it take for the hairpin go reach the ground?

Which inequality has a dashed boundary line when graphed ?

What percent of 18 is 24? and plz explain thx.

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
