Answer 1

Square root of 13^2 - 12^2 = 5

Answer 2

Answer:

B. 5

Step-by-step explanation:

Use the pythagorean theorem to solve: [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex].

[tex]a^{2}[/tex]+[tex]12^{2}[/tex]=[tex]13^{2}[/tex]

[tex]a^{2}[/tex]+144=169

Subtract 144 from 169.

[tex]a^{2}[/tex]-144=169-144

[tex]a^{2}[/tex]=25

Square root to get a.

[tex]\sqrt{a}[/tex]=[tex]\sqrt{25}[/tex]

a= 5

A horizontal line passes through the
point (0,4). A vertical line passes
through the point (-16,0). What is
the intersection of the two lines?

Answers

Given:

A horizontal line passes through the point (0,4).

A vertical line passes through the point (-16,0).

To find:

The intersection point of these two lines.

Solution:

A horizontal line passes through the point (0,4). It means the y-coordinate of each point on the line is 4 and the equation of the line is

[tex]y=4[/tex]

A vertical line passes through the point (-16,0). It means the x-coordinate of each point on the line is -16 and the equation of the line is

[tex]x=-16[/tex]

So, the coordinates of the intersection point of these two lines are (-16,4).

Therefore, the required point is (-16,4).

The point of intersection of the two lines is at point: (-16, 4).

According to the question;

The horizontal line passes through the point (0,4).

The vertical line passes through the point (-16,0).

If a horizontal line passes through the point (0,4).

In essence, the y-coordinate of each point on the line is 4 and the equation of the line is; y = 4

If a vertical line passes through the point (-16,0).

In essence, the x-coordinate of each point on the line is -16 and the equation of the line is; x = -16

Ultimately, the intersection point of the two lines as described is (-16,4).

What is the mean of the values in the dot plot?

Enter your answer in the box.

Answers

Answer:

The mean is 46.

Step-by-step explanation:

To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.

40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50

Multiply what's in the parentheses.

40 + 82 + 45 + 96 + 147 + 50

Add, going from left to right

122 + 45 + 96 + 147 + 50

167 + 96 + 147 + 50

263 + 147 + 50

410 + 50

460

Now, divide that by how many dots there were (10).

460/10

The mean of the values in this dot plot is 46.
