Answer: missing value is 3
Step-by-step explanation:To find the vertex form of parabola given in almost standard form were written following steps:
1. Write the function in standard form:
2. Factor a out of the first two terms:
3. Form a perfect square trinomial:
4. Write the trinomial as a binomial squared:
The vertex is (-3,-27).
The question here is how long does it take for a falling
person to reach the 90% of this terminal velocity. The computation is:
The terminal velocity vt fulfills v'=0. Therefore vt=g/c,
and so c=g/vt = 10/(100*1000/3600) = 36,000/100,000... /s. Incorporating the
differential equation shows that the time needed to reach velocity v is
t= ln [g / (g-c*v)] / c.
With v=.9 vt =.9 g/c,
t = ln [10] /c = 6.4 sec.
73 that will be hope this is right ok byeeee
