suppose the planes will meet after x hours of flying.<br />
<br />
the first plane will cover 420x miles the second one will cover 330x miles<br />

so the total distance covered by both planes will be 420x + 330x = 1000 miles<br />

A plane flying the 3458 mile trip from NYC to London has a 50mph tailwind.

It would take 1 hour 48 minutes with a tailwind of the same speed. Find the headwind and speed of plane in still air.
https://www.mathhomeworkanswers.org/247903/travels-against-headwind-minutes-tailwind-headwind-plane?show=247907#a247907
<p style="text-align: justify;">Let S be the speed of the plane in still air. With a headwind its speed is S-w where w is the headwind speed and S+w for the tailwind.
<br>
<br>
Distance is 270 miles. 270=3(S-w)=1.8(S+w)
<br>
<br>
3S-3w=1.8S+1.8w, 1.2S=4.8w, S=4w.
<br>
<br>
So 270=3(3w) and w=270/9=30mph. So S=120mph.

Wind speed is 30mph, plane speed is 120mph.</p>Algebra 2 Answershttps://www.mathhomeworkanswers.org/247903/travels-against-headwind-minutes-tailwind-headwind-plane?show=247907#a247907Thu, 09 Nov 2017 19:39:48 +00002. Given that

<p style="text-align: justify;">3x²-x-1=0 (we can solve this using the quadratic formula)
<br>
<br>
SOLUTION BY COMPLETNG THE SQUARE
<br>
<br>
Divide through by 3:
<br>
<br>
x²-x/3-1/3=0
<br>
<br>
Take half the coefficient of the x term and square it: so we halve 1/3 to get 1/6, and square it to get 1/36.
<br>
<br>
Move the constant to the other side of the equals sign:
<br>
<br>
x²-x/3=1/3
<br>
<br>
Now add 1/36 to both sides:
<br>
<br>
x²-x/3+1/36=1/3+1/36=12/36+1/36=13/36.
<br>
<br>
We just completed the square on the left hand side:
<br>
<br>
(x-1/6)²=13/36
<br>
<br>
Now we take the square root of each side:
<br>
<br>
x-1/6=±√(13/36)=±√13/6
<br>
<br>
So x=1/6±√13/6 or (1±√13)/6. This gives us 2 values for x=(1+√13)/6=0.7676 and (1-√13)/6=-0.4343 approx.
<br>
<br>
Using the quadratic formula gives us the same result.</p>Algebra 2 Answershttps://www.mathhomeworkanswers.org/247684/solve-3x-squared-minus-x-minus-1-0?show=247686#a247686Sun, 05 Nov 2017 22:04:42 +0000Answered: 2a^2=-6+8a

https://www.mathhomeworkanswers.org/247315/what-is-the-maximum-height?show=247318#a247318
<p style="text-align: justify;">Use S=ut-gt²/2 where S is vertical height, u=64’/s, t is the time in secs, g=9.8’/s², accn of gravity.
<br>
<br>
Differentiate this wrt t: u=gt, t=u/g=64/9.8=6.53 secs to reach maximum height.
<br>
<br>
S=u²/g-g(u/g)²/2=u²/2g=2048/9.8=208.98 ft. This is from the level of the platform, so from the ground it is 288.98 ft.</p>Algebra 2 Answershttps://www.mathhomeworkanswers.org/247315/what-is-the-maximum-height?show=247318#a247318Sat, 28 Oct 2017 01:21:48 +0000Answered: What is the absolute maximum for 2x^3-3x^2-5?

https://www.mathhomeworkanswers.org/247028/1-5x-8-3?show=247047#a247047
| x/5-8 |=3 means x/5-8=3 and 8-x/5=3.<br />
<br />
That means x=55 or x=25 by solving each for x.<br />
<br />
No other values of x make the equality true. Intervals apply for inequalities not equalities.<br />
<br />
If we replace = with ≤ we get x≤55 and x≥25 and the interval is [25,55].<br />

This is the result in interval notation for solving | x/5-8 |≤3.Algebra 2 Answershttps://www.mathhomeworkanswers.org/247028/1-5x-8-3?show=247047#a247047Sun, 22 Oct 2017 15:17:36 +0000Answered: Sam drove to the mountains last weekend.
