Help me please !!!!!!!!!!

Answer: 3

Step-by-step explanation:

1. 2²=4

2. 4*5=20

3. 180/20=9

4. √9=3

Hope this helped :)

Answer:

x = 3

Choice 2

Step-by-step explanation:

180 = 2^2 * x^2 * 5

180 = 20x^2

9 = x^2

x = 3

Checking:

180 = 2^2 * 8^2 * 5

180 = 4 * 9 * 5

180 = 36 * 5

180 = 180

Answer:

(7 , 5)

Step-by-step explanation:

Add all the x-axis then divide by 3

7 + 3 + 11 = 21

21/3 = 7

Add all the y-axis then divide by 3

9 + 3 + 3 = 15

15/3 = 5

So answer will be (7,5)

The coordinates of the centroid of triangle ABC.

(x, y)

Where,

x = Sum all the x-coordinates of the vertices ÷ 3

y = Sum o

The coordinates of the centroid is (7, 5).

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

The vertices of the triangle in the diagram below are:

A(7,9), B(3,3), and C(11,3).

Now,

The coordinates of the centroid of triangle ABC.

(x, y)

Where,

x = Sum all the x-coordinates of the vertices ÷ 3

y = Sum of the y-coordinates of the vertices ÷ 3

Now,

x = 7 + 3 + 11 / 3 = 21/3 = 7

y = 9 + 3 + 3 / 3 = 15/3 = 5

Now,

The coordinates of the centroid is (7, 5).

Step-by-step explanation:

[tex]y = {2.5}^{2} - 2(2.5) - 3 [/tex]

-1.75

Here we need to learn how to read a graph.

In a normal graph we have the inputs (the values of x) in the horizontal axis and the outputs in the vertical axis.

Here we want to see what is the value of y for the blue graph when x = 2.5

We will find y = -1.5

(the blue graph is the one that corresponds to: y = x^2 - 2x - 3)

To find this:

The first thing we need to do is find x = 2.5 in the horizontal axis.

Now that we found it, we need to draw a vertical line, and see at which point of the blue graph this vertical line intersects the curve. At that point we draw an horizontal line that intercepts the vertical axis.

At that point we have the y-value

You can see an example of this, a good estimation by only looking at the graph is y = -1.5

For the other point, the value of x when y = 1.

We do exactly the same thing but in the inverse order, we first find y = 1

Then we draw an horizontal line that intercepts the graph

Then we draw a vertical line that intercepts the x-axis and we find the value.

We can see that for y = 1 we have x = 3.2 aprox.
