Amodel rocket is launched with an initial upward velocity of 54 m/s. the rocket's height h (in meters) after t seconds is given by the following.

Step-by-step explanation:

Let's first put that polynomial in standard form by descending powers of t:

If we are looking for the times where the rocket is at a height of 26 m, we sub in a 26 for h(t) and factor to solve for t.  First we get all the terms on one side of the equals sign and set it equal to zero.

That is a second degree polynomial so you can factor it however you are most comfortable to get the values of t are:

t = .51 sec and t = 10.29 sec

Since this is a polynomial, there will be 2 values of t for this time with y being the height and x being the time.  The parabola is symmetrical about the vertex so there are 2 values of t (or x) that equal height (or y).

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week
