Plzz help me to find coefficient in binomial theorem (25 points)
Viefleur [7K]

<em>Denote x2 by y. </em>

<em>  </em>

<em>(x2-3)7=(y-3)7 </em>

<em>  </em>

<em>This is a binomial expansion in y, and you want the coefficient of y4 because y4=x8 </em>

<em>  </em>

<em>You have 7 terms of (y-3) in (y-3)7.  To get the fourth power of y, you need to choose y from four of the terms.  The number of ways you can do this is the combinations of 7 things taken 4 at a time.  This is: </em>

<em>  </em>

<em>7!/(4!3!)=35</em>

<em />

<em>So, the coefficient of x8 in the given expansion will be 210.</em>

<em>HOPE IT HELPS</em>

<em>THANK YOU </em>

Marat540 [252]

Answer:

  33 1/3 lb

Step-by-step explanation:

When the distance between them goes from 8 ft to 12 ft, it is 1.5 times what it was. Then the force will be multiplied by the inverse of the square of this:

  (75 lb)×1/(1.5²) = 75/2.25 lb = 33 1/3 lb

At 12 feet apart, the attraction force is 33 1/3 pounds.
