Plz help me solve it the question is below

AlladinOne [14]

Answer:

$\frac{1024}{2025}$

Step-by-step explanation:

$\frac{3}{4}^{-4} = \frac{1}{\frac{3}{4}^{4} }$

(3/4)^4 = 81/256

1 ÷ 81/256 = 256/81

So;

$\frac{256}{81} * \frac{4}{9} = \frac{1024}{729}$

$\frac{1024}{729} / n = \frac{1}{9/25}$

$\frac{1024}{729n} = \frac{25}{9} \\\\n = \frac{1024 *9 }{25 * 729} = \frac{1024}{2025}$

Find the value of x. Write your answer in simplest form.

Brilliant_brown [7]

Answer:

by using Pythagoras theorm

${x}^{2} + {x}^{2} = {(9 \sqrt{2)} }^{2} \\ 2 {x}^{2} = 81 \times 2 \\ 2 {x}^{2} = 162 \\ {x}^{2} = 81 \\ x = \sqrt{81} \\ x = 9$

This event is independent, true or false?

egoroff_w [7]

Answer:

False

Step-by-step explanation:

Because the question says you pick a <u>different</u> shirt on Tuesday than on Monday, that means you have one less shirt you can select, so the event is dependent.

Determine if the sequence converges: [ln(n)]^2 /n

Finger [1]

We will use l´Hopital´s rule for calculating limits involving indeterminate form (in this case: ∞ / ∞ ) using the derivative of the numerator and denominator: $\lim_{n \to \infty} \frac{ln^{2}n }{n} = \lim_{n \to \infty} \frac{2ln(n)* \frac{1}{n} }{1} = \lim_{n \to \infty} \frac{2ln(n)}{n}$ This is still form ∞/∞ and we will use the derivative again: $\lim_{n \to \infty} \frac{2ln(n)}{n} = \lim_{n \to \infty} \frac{ \frac{1}{n} }{1} = \lim_{n \to \infty} \frac{1}{n}$ =1/∞ = 0
The sequence converges.
