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.

Change negative exponents to positive. then solve. round to four decimal places

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
