A regular polygon has an exterior angle of 8. what is the sum of all the interior angles
Bogdan [553]

Answer:

7740 degrees.

Step-by-step explanation:

The sum of the exterior angles of all polygons add up to 360 degrees.

So the number of sides and the number of interior angles  in this polygon = 360 / 8 = 45.

Each internal angle = 180 - 8 = 172 degrees, so the sum of all interior angles

= 172 * 45

= 7740 degrees,

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! I CANNOT RETAKE THIS!!
Alexxx [7]

(x - 5i√2)(x +5i√2)

given the roots of a polynomial p(x), say x = a and x = b

then the factors are (x - a)(x - b)

and p(x) is the product of the factors ⇒ p(x) = (x - a)(x - b)

here x² + 50 = 0 ⇒ x² = - 50 → ( set = 0 for roots)

take the square root of both sides

x = ± √-50 = ±  √(25 × 2 × -1) = √25 × √2 × √-1 = ± 5i√2

The roots are x = ± 5i√2

thus the factors are ( x - ( - 5i√2)) and (x - (+5i√2))

x² + 50 = (x + 5i√2)(x - 5i√2)

Which graph best represents -5y = -6x + 15
frutty [35]

Answer: Option c.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Given the equation:

-5y = -6x + 15

Solve for "y" in order to write in Slope-Intercept form:

y = \frac{-6}{-5}x + \frac{15}{-5}\\\\y = \frac{6}{5}x -3

Now you can identify that that the slope and the y-intercept are:

m=\frac{6}{5}\\\\b=-3

A posive slope means that the the line moves upward from left to right.

With this information, you can conclude that the the graph that  best represents the given equation is the graph shown in the Option c.

Debbie is correct because you can not a percentage of a person therefore you have to round it, and if there was 5,000 female athletes in 2008 and 4,700. If you take 5,000 and subtract 4,700; the answer is 300.
