What is the measure of each interior angle of a regular 15-gon?

Mathematics
1 answer:
Romashka [77]3 years ago
5 0

Answer:

156

Step-by-step explanation:

1) The formula for finding the sum of interior angles of an n-gon is 180(n-2)

2) Plug in 15 for n

180(15-2)

3) Solve

180(15-2)

180(13)

2340

4) There are 15 angles in a 15-gon

5) Divide sum of interior angles by number of interior angles

2340/15 = 156

6) So, the answer is 156 degrees

The number at the end of the equation shifts the graph up or down.

Changing the 1/2 to a -2 would shift the graph down which would change the y-intercept.

The answer is D.

Is (5x+4) a factor of (-21x^2-15-40x+5x^3
Tamiku [17]

Answer:

No. It is not.

Step-by-step explanation:

Dividing 5x³+21x²-40x-15 by 5x+4 gives x²+5x-4 with a remainder. Which means, 5x+4 is not a factor of 5x³+21x²-40x-15

The total cost for buying new sneakers for the basketball team an be found by using the function y=25x + 65, is where x is the n
gtnhenbr [62]

Answer:

Domain\ =\ \{x: 9,10,11....16\}

<em></em>Range\ =\ \{y:290, 315,340.....465\}<em></em>

Step-by-step explanation:

Given

y = 25x + 65

Required

Determine the range and domain when x = 9 to 16

The domain is the set of

Domain\ =\ \{x: 9,10,11....16\}

Solving for the range;

<em>When x = 9</em>

<em></em>y = 25 * 9 + 65<em></em>

<em></em>y = 225 + 65<em></em>

<em></em>y = 290<em></em>

<em></em>

<em>When x = 10</em>

<em></em>y = 25 * 10 + 65<em></em>

<em></em>y = 250 + 65<em></em>

<em></em>y = 315<em></em>

<em></em>

<em>When x = 11</em>

<em></em>y = 25 * 11 + 65<em></em>

<em></em>y = 275 + 65<em></em>

<em></em>y = 340<em></em>

<em></em>

<em>You continue till you get to x = 16</em>

<em>---</em>

<em>--</em>

<em>-</em>

<em>When x = 16</em>

<em></em>y = 25 * 16 + 65<em></em>

<em></em>y = 400 + 65<em></em>

<em></em>y = 465<em></em>

<em></em>

<em>Hence; the range is</em>

<em></em>Range\ =\ \{y:290, 315,340.....465\}<em></em>
