Evaluate the expression 11C4.

kicyunya [14]

The correct answer is: 330

Explanation:

The formula for combination is given as follows:

$^nC_r = \frac{n!}{r! (n-r)!}$ --- (1)

Where n = 11

r = 4

Plug in the values in equation (1) and calculate:

$^nC_r = \frac{n!}{r! (n-r)!} \\ ^{11}C_{4} = \frac{11!}{4! (11-4)!} \\ ^{11}C_{4} = \frac{11*10*9*8*(7!)}{4! (7)!} \\ ^{11}C_{4} = \frac{11*10*9*8}{4!} \\ ^{11}C_{4} = \frac{11*10*9*8}{4*3*2*1} \\ ^{11}C_{4} = 330 \\$

Hence the correct answer is 330.

Differentiate the following equation

Bingel [31]

Answer:

$\frac{dy}{dx} = \frac{4}{1-x}$

Step-by-step explanation:

y = 3 - 4ln(1 - x)

⇒ $\frac{dy}{dx} =3\frac{d}{dx} -4ln(1-x)\frac{d}{dx}$

⇒ $\frac{dy}{dx} =0 -4ln(1-x)\frac{d}{dx}$

⇒ $\frac{dy}{dx} =0 -4(\frac{1}{1-x})\times-1$

⇒ $\frac{dy}{dx} = \frac{4}{1-x}$
