Answer:

0.6 (terminating), 0.5, 0.375

Step-by-step explanation:

I would assume you are wanting these in decimal form. In that case, you would have:

2/3 = 0.6 (terminating)

1/2 = 0.5

3/8 = 0.375

Well you know that 1/2 will be in the middle of 0 and 1 so you can place that point, then 2/3 is just a little bigger than that so you can divide your whole number line (of 0 to 1 ) into three sections and place 2/3 on the second line, then, 3/8 is almost 4/8=1/2 so just put it a little below your 1/2 point

Find the integration of (1-cos2x)/(1+cos2x)

slega [8]

Given:

The expression is:

$\dfrac{1-\cos 2x}{1+\cos 2x}$

To find:

The integration of the given expression.

Solution:

We need to find the integration of $\dfrac{1-\cos 2x}{1+\cos 2x}$ .

Let us consider,

$I=\int \dfrac{1-\cos 2x}{1+\cos 2x}dx$

$I=\int \dfrac{2\sin^2x}{2\cos^2x}dx$ $[\because 1+\cos 2x=2\cos^2x,1-\cos 2x=2\sin^2x]$

$I=\int \dfrac{\sin^2x}{\cos^2x}dx$

$I=\int \tan^2xdx$ $\left[\because \tan \theta =\dfrac{\sin \theta}{\cos \theta}\right]$

It can be written as:

$I=\int (\sec^2x-1)dx$ $[\because 1+\tan^2 \theta =\sec^2 \theta]$

$I=\int \sec^2xdx-\int 1dx$

$I=\tan x-x+C$

Therefore, the integration of $\dfrac{1-\cos 2x}{1+\cos 2x}$ is $I=\tan x-x+C$ .

steposvetlana [31]

Answer:

Aisha gross pay equals $472

Step-by-step explanation:

If Aishat is paid $8.00 per hour, then for 39 hours, she will get

39 × 8 = $312

She gets 4% commission on all sales. If her sale is $4000, the her commission will be

4000 × 4/100

= $160

Then her total gross income will be $312 + $160 = $472

Using graph paper, determine the line described by the given point and slope. Click to show the correct graph below. (0, -2) and

BaLLatris [955]

Answer:

y = -(5/2)x -2

Explanation:

The general formula for a straight line is y – mx + b.

The image below shows the graph of the line.

Step 1. <em>Calculate the slope</em>.

Slope = m = Δy/Δx = (y₂-y₁)/(x₂-x₁)

x₁ = 0; y₁ = -2

x₂ = -2; y₂ = 3 Calculate m

m = [3-(-2)]/(-2-0)

m = (3+2)/(-2)

m = 5/(-2)

m = -5/2

Step 2. <em>Calculate the y-intercept </em>

When x = 0, y = 2.

The y-intercept (b) is at y = -2

Step 3. <em>Write the equation </em>for the graph

y = mx + b

y = -(5/2)x - 2
