An air force pilot is flying at a cruising altitude of 9000 feet and is forced to eject from her aircraft. The function h(t)=-16t+128t+900. Determine and state the vertex of h(t)

  (t, h(t)) = (4, 9256)

Step-by-step explanation:

We assume you intend the h(t) function to be ...

  h(t) = -16t^2 +128t +9000

The equation can be written in vertex form as follows:

  h(t) = -16(t^2 -8t) +9000

  h(t) = -16(t^2 -8t +16) +9000 -(-16)(16) . . . . add and subtract -16(16) to complete the square

  h(t) = -16(t -4)^2 +9256 . . . . . vertex form of the height function

The vertex of h(t) is (4, 9256), an altitude of 9256 feet after 4 seconds.

The answer id b bro yes

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
