Let [n] represent the greatest even integer less than n that divides n, for any positive integer n. For example, [24] = 12. What

ipn [44]

First you write down all even integers that divide 20.

Those are: 2,4,10,20

Since the request is that integer is less than n, 20 cannot be the answer.
This means that greatest even integer is 10

Answer is 10.

The sum of the infinite geometric series is -288.

<h2>Given that</h2>

A finite geometric series with n = 4, a₁ = -144, and r = ½.

<h3>We have to determine</h3>

What is the sum of the infinite geometric series?

<h3>According to the question</h3>

The sum of the infinite is determined by the following formula;

$\rm S\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\$

A finite geometric series with n = 4, a₁ = -144, and r = ½.

Substitute all the values in the formula;

$\rm S\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\S\infty = \dfrac{-144 (1- \dfrac{1}{2}^4)}{1-\dfrac{1}{2}}\\\\S \infty = \dfrac{-144 \times \dfrac{15}{16}}{\dfrac{1}{2}}\\\\S \infty = -270$

Therefore,

The sum of the infinite geometric series is,

$\rm S = \dfrac{a_1}{1-r}\\\\S=\dfrac{-144}{1-\dfrac{1}{2}}\\\\S = \dfrac{-144}{0.5}\\\\S = -288$

Hence, the sum of the infinite geometric series is -288.

At takeoff a plane flies at an angle of 10 degrees with the runway. After it has traveled a ground distance of 2,800 ft. Find th

Sonja [21]

<h2>Vertical distance gained from takeoff is 493.72 ft</h2>

Step-by-step explanation:

Refer the figure.

Horizontal distance = AB = 2800 ft

Angle = ∠B = 10°

We need to find AC that is h.

We have

$tanB=\frac{AC}{AB}\\\\tan10=\frac{h}{2800}\\\\h=2800\times tan10=493.72ft$

Vertical distance gained from takeoff = 493.72 ft

Can x8 x y3 be written as a single power

NeX [460]

$x^{8} *y^{3}$ can only be written as $x^{8}* y^{3}$ or as $x^{8} y^{3}$ . One has the multiplication sign the other does not, which is why we put it together, because we know that if they are together they will be multiplied.

I hope this helps, if you have any other question on this or any other question, just ask. I am here to help.
