Similar figures are the same shape but not the same size. you can find out the scale by using parallel lines.

Answer:

*You could just look it up.

Here's what I found on google:

Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent, and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.

So basically, similar figures are 2 figures that are the same shape.

They don't have to be the same size.

Verify the identity. 4 csc 2x = 2 csc2x tan x

vlada-n [284]

Step-by-step explanation:

$4csc(2x) = 2csc^2(x) tan(x)$

We start with Left hand side

We know that csc(x) = 1/ sin(x)

So csc(2x) is replaced by 1/sin(2x)

$4 \frac{1}{sin(2x)}$

Also we use identity

sin(2x) = 2 sin(x) cos(x)

$4 \frac{1}{2sin(x)cos(x)}$

4 divide by 2 is 2

Now we multiply top and bottom by sin(x) because we need tan(x) in our answer

$2\frac{1*sin(x)}{sin(x)cos(x)*sin(x)}$

$2\frac{sin(x)}{sin^2(x)cos(x)}$

$2\frac{1}{sin^2(x)} \frac{sin(x)}{cos(x)}$

We know that sinx/ cosx = tan(x)

Also 1/ sin(x)= csc(x)

so it becomes 2csc^2(x) tan(x) , Right hand side

Hence verified

1.) What is slope and how is it determined from an graph?

Daniel [21]

1) Slope tell about the steepness of the line.

To find slope we look at the rise and run between 2 points.

attached the graph of line with slope

slope = $\frac{change in y values ( rise)}{change in x value (run)}$

= $\frac{2}{1}$

So slope = 2

2) we have x and y intercepts

x intercept is the point where the line crosses x axis

x intercept at x= 3

y intercept is the point where the line crosses y axis

y intercept at y= 6

3) Linear equation is y= 3x+2

function is f(x) = 3x+2

We can graph it using slope and y intercept

In f(x)= 3x + 2 , slope =3 and y intercept = 2

slope = 3, rise = 3 and run =1

The graph of f(x)= 3x+2 is attached below.

Two intersecting lines lie in two planes.<br><br> A. True<br> B. False

Lady_Fox [76]

Intersecting lines can be lying in a plane. An example is the Cartesian coordinate system where systems of equations can be defined by their intesecting points by plotting the equations in the plane coordinate system. In this case, the answer to this problem is B. False

You work 25 hours per week. You need to earn $240 to cover your weekly expenses. Your job as a dog walker pays $10 an hour. Your

qwelly [4]

Answer:

(8×5)+(10×20)=240

Step-by-step explanation:

8 (Car wash hourly pay $$) times 5 (hours worked) equals 40(money earned). And 10 (dog walker money $$) times 20 (hour worked) equals 200(money earned). 200(dog walker) plus 40(car washer) is 240. So if you do 5 hours at the car wash and 10 hours of dog walking, you'll earn enough to cover your expenses.
