So, making x subject of the formula, x = [m - 2pt³ ±√(m² - 4pt²m)]/{2t⁵}
<h3>How to make x subject of the formula?</h3>
Since p = √(mx/t) - t²x
So, p + t²x = √(mx/t)
Squaring both sides, we have
(p + t²x)² = [√(mx/t)]²
p² + 2pt²x + t⁴x² = mx/t
Multiplying through by t,we have
(p² + 2pt²x + t⁴x²)t = mx/t × t
p²t + 2pt³x + t⁵x² = mx
p²t + 2pt³x + t⁵x² - mx = 0
t⁵x² + 2pt³x - mx + p²t = 0
t⁵x² + (2pt³ - m)x + p²t = 0
Using the quadratic formula, we find x.
where
- a = t⁵,
- b = (2pt³ - m) and
- c = p²t
Substituting the values of the variables into the equation, we have
So, making x subject of the formula,

Answer:
longitudinal profile depicts the changes in elevation as a function of distance
Step-by-step explanation:
Hope this helps :)
Answer:
here is your answer.. these are basic questions we just need to put value..i hope you get it..
Simple....
you have: 4(x+7)
To simplify it..distribute..
4(x+7)
4*x=4x
and
4*7=28
Leaving you with...
4x+28
As we can see B is 4x+28
Thus, your answer.
So 6.00 - .99 = 5.01 which give 20 mins
5.01 divided by .07 a min = around 71.5
20 + 71.5 is 91.5, so she can talk for about 91 full mins
