Answer:

The set of solution is {-9,-4}

Step-by-step explanation:

* We use this result: A.B=0 , that means A=0 or B=0.

* (x+9)(x+4)=0, then x+9=0 or x= - 9

Or x+4=0, x= - 4.

This equation has 2 solutions: - 9 and - 4.

Hope that useful for you.

The function h defined by h(t)=(49 + 4.9t)(10 - t) models the height, in meters, of an object t seconds after it is dropped from

kipiarov [429]

Answer:

Step-by-step explanation:

Let's FOIL this out and get it into standard quadratic format:

$h(t)=-4.9t^2+490$ . The lack of a linear term in the middle means therewas no upwards velocity, consistent with the object being dropped straight down as opposed to thrown up in the air tand then falling in a parabolic path. The -4.9t² represents the acceleration due to gravity, and the 490 represents the height from which the object was dropped. The constant in a quadratic that is modeling parabolic motion always represents the height from which the object was dropped (or launched). That's how you know.
