The density of hydrogen at 20 degrees C is 1.4x10^-3g/cm^3. Express this density in decimal form.

In the figure, AB is divided into equal parts. The coordinates of point A are (2, 4), and the coordinates of point B are (10, 6)

Rudiy27

Diving the length AB into equal parts gives;

$D→\left (4 \:,4.5\right)$

$E→\left (5 \:,4.75\right)$

$H→\left (8 \:,5.5\right)$

$I →\left (9 \:,5.75\right)$

<h3>How can the coordinates of the points be found?</h3>

The number of equal parts obtained by counting are 8

Coordinates of point A is (2, 4)

Coordinates of point B is (10, 6)

Therefore;

Coordinates of point C is

$\mathbf{ \left (2 + \frac{10 - 2}{8},\: 4 + \frac{6 - 4}{8}\right) }= \left (3 \:, 4.25\right)$

Coordinates of point D are;

$\mathbf{\left (2 + \frac{10 - 2}{4} \: , 4 + \frac{6 - 4}{4}\right) }= \left (4 \:,4.5\right)$

Coordinates of point E are;

$\mathbf{\left (2 + \frac{8 \times 3}{8} \: , 4 + \frac{2 \times 3}{8}\right)} = \left (5 \:,4.75\right)$

Coordinates of point F are;

$\mathbf{\left (2 + \frac{8 \times 4}{8} \: , 4 + \frac{2 \times 4}{8}\right)} = \left (6 \:,5\right)$

Coordinates of point H are;

$\mathbf{\left (2 + \frac{8 \times 6}{8} \: , 4 + \frac{2 \times 6}{8}\right)} = \left (8 \:,5.5\right)$

Coordinates of point I are;

$\mathbf{\left (2 + \frac{8 \times 7}{8} \: , 4 + \frac{2 \times 7}{8}\right)} = \left (9 \:,5.75\right)$

Which gives;

$D→\left (4 \:,4.5\right)$

$E→\left (5 \:,4.75\right)$

$H→\left (8 \:,5.5\right)$

$I →\left (9 \:,5.75\right)$

(2^3//4^2)^5 What is the equivelant expression?

frosja888 [35]

Answer:

A

Step-by-step explanation:

This is the same as ((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2)) which is equal to (2^(3+3+3+3+3)/4^(2+2+2+2+2)), so its (2^15/4^10)

Consider the arithmetic sequence log x + log √2, 2 log x + log 2, 3 log x + log 2√2......

likoan [24]

Answer:

See below

Step-by-step explanation:

Given sequence:

log x + log√2, 2logx + log 2, 3logx + log2√2, ...

a)

The terms can be rewritten as:

T(1) = log x + log√2 = log x√2
T(2) = 2logx + log 2 = 2logx + 2 log√2 = 2log x√2
T(3) = 3logx + log2√2 = 3logx + 3log√2 = 3log x√2
...
T(n) = n log x√2 (option A)

b)

Sum of the first n terms:

log x√2 + 2log x√2 + ... + nlog x√2 =
log x√2(1 + 2 + ... + n) =
log x√2 (1 + n)*n/2 =
1/2n(n + 1)log x√2

Sum of the first 40 terms:

1/2*40(40 + 1)log x√2 =
820log x√2
