S=1 - 1/4 + 1/6 - 1/9 + 1/11 - 1/14..........infinity. Find the sum of series.

Ann [662]

$1+\frac{1}{6}+\frac{1}{11}+\cdots=\sum^{\infty}_{n=1} \frac{1}{5n-4} \\ \\ \frac{1}{4}+\frac{1}{9}+\cdots=\sum^{\infty}_{n=1} \frac{1}{5n-1} \\ \\ S=\sum^{\infty}_{n=1} \left(\frac{1}{5n-4} -\frac{1}{5n-1} \right) \\ \\ =\frac{\pi}{5} \sqrt{\frac{1}{5} (5+2\sqrt{5})}$

Answer:

Commutative

Step-by-step explanation:

Given

$3 + b + 2 = 3 + 2 + b$

Required

What law is applied

The applied law is commutative law of addition.

This law states that:

$a + b = b + a$

So:

$3 + b + 2 = 3 + (b + 2)$

When the positions of 2 and b are interchanged, we have:

$3 + b + 2 = 3 + (2 + b)$

Remove bracket

$3 + b + 2 = 3 + 2 + b$

On the freeway, it is unsafe to drive too slowly or too quickly. The safest driving speeds on the freeway near Allan’s town were

meriva

Answer:

59.0 miles per hour

Step-by-step explanation:

When you have an equation with an absolute value, you must consider two options: one with a positive result and another one with a negative result.

$x-55 = 4.2\\x = 4.2 + 55\\x = 59.2\\\\And\\\\x-55 = -4.2\\x=-4.2 + 55\\x = 50.8$

In this case you need the maximum safe driving speed which is 59.2 miles per hour
