The equation models the height in feet reached in seconds by an object propelled straight up from the ground at a speed of 80ft/s.

Use the discriminant to find whether the object will ever reach a height of 90ft.

The discriminant is ___(3 number places.) Since it is Positive or Negative, the object Will or Will Not reach a height of 90ft.

Which polynomial function has x intercepts -1, 0, and 2 and passes through the point (1, -6)

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?

In 2009, there were 1570 bears in a wildlife refuge. in 2010, the population had increased to approximately 1884 bears. if this trend continues and the bear population is increasing exponentially, how many bears will there be in 2018?
