Answer:

19 sides

Step-by-step explanation:

Sum of angles of n-side polygon = 180 *(n - 2)

180 *(n -2) = 3060

Divide both sides by 180

n- 2 = 3060/180

n - 2 = 17

n = 17+2

n = 19

Answer:

19 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here sum = 3060° , then

180° (n - 2) = 3060° ( divide both sides by 180° )

n - 2 = 17 ( add 2 to both sides )

n = 19

The polygon has 19 sides

What is 0.5 repeating as a fraction in simplest form

Solnce55 [7]

Answer:

5/9

Step-by-step explanation:

Start be letting x = 0.555...

Our original equation is:

x = 0.555...

There is only one digit repeating, the 5, so we multiply both sides of that equation by 10 and write it above the original equation.

10x = 5.555...

x = 0.555...

Now we subtract the second equation from the first equation as written above.

9x = 5

Divide both sides by 9.

x = 5/9

0.555... = 5/9

Consider the function f(x). Select all of the following that include a vertical stretch of f(x)

zhenek [66]

Answer:

F , D, A

Step-by-step explanation:

As we know vertical stretch of f(x) happens when we chane the value of the patameter a in this general form:

y = a. f(k(x-d))+ c

when |a| > 1 because When |a| > 1 (when a is greater than 1), the function is stretched vertically by a dilation factor of |a|.

So we choose, F , D, A

What is the slope of the line that goes through (2, 5) and (-6, -2) ?

alexira [117]

Answer:
slope = 7/8

Explanation:
Slope of the line can be calculated using the following equation:
slope = $\frac{y2 - y1}{x2 - x1}$

The two points given are:
(2,5) representing (x1 , y1)
(-6,-2) representing (x2 , y2)

Substitute with the points in the above equation to get the slope as follows:
slope = $\frac{-2 - 5}{-6 - 2}$ = 7/8

Hope this helps :)
