2nd term of (2r-3s)^12
earnstyle [38]

Answer:

1.-12*(2r)^11 * (3s)

= -12*2048*3 r^11 s

= -73728 r^11 s

2.12C1 (2r)¹¹(-3s) = -36(2¹¹)r¹¹s = -73728r¹¹s

3.24 r - 36 s

The second term: -36 s

4.(2r-3s)^12

= (2r)^12 + 12C1 (2r)^11 (-3s)

= 2^12 r^12 + (12) 2^11 r^11 (-3) s

= 4096 r^12 - (12)(3)(2098) r^11 s

= 4096 r^12 - 73,728 r^11 s + .....

-73,728 r^11 s

A trough is 9 feet long, and its cross section is in the shape of an isosceles right triangle with hypotenuse 2 feet, as shown a
Andrei [34K]

Answer:

1/6

Step-by-step explanation:

Given:

  • Length of the trough: 9 ft

=> The volume of the trough: V =\frac{9}{2} * (b * h) (1)

  • An isosceles right triangle with hypotenuse 2 feet

=> the other two sides of the triangle is:

= tan(45 degrees) = h/(b/2)

<=> b = 2h   substitute in (1), we have:

V = \frac{9}{2}  *(2h *h) = 9h^{2}  

Take derivative of volume with respect to time to find equation for rate of filling the trough

dV/dt = 2 * 9 *h dh/dt = 18h dh/dt

<=> dh/dt = dV/dt /(18h)

As we know that, dV/dt = 2

So, dh/dt = 2 / 18h  = 1/9h

<=> V = t * rate = 2 * 2 = 4

But V = 9h^{2}    

<=> 9h^{2}     = 4

<=> h = 2/3  

The rate is the height h feet of the water in the trough changing 2 minutes after the water begins to flow:

dh/dt = 1/(9h) = 1/(9 * 2/3) = 1/6
