Answer: N= 135, M=45.

Step-by-step explanation:The formula to find the degree inside of a shape is: (n-2)180. This is an octagon, so it has 8 sides, plug this in for n.

8-2 * 180

1080                              divide by 8 to get the value of n

n=135

The formula for an angle outside of the shape is:

360/n   n is still eight, so plug this in for n

360/8

m=45

Answer:

<em>n = 135 degrees ( ° ) ,</em>

<em>m = 45 degrees ( ° )</em>

Step-by-step explanation:

<em>* Sorry I didn't answer this before *</em>

1. In this figure we can see that this visual is a representation of an octagon, provided it's 8 sides.

2. Knowing this, let us split this figure into triangle 180 degrees each ⇒ compute the total interior angles in degrees.

3. If you were to draw lines from one vertex to any other non-adjacent vertices, it would be that 6 triangles are formed.

4. One triangle ⇒ 180 degrees ( ° ) so that this octagon ⇒ 180° * number of triangles, or ⇒ 180 * 6 = 1080°

5. Knowing that this shape is a regular polygon, all angles are congruent such that if x represents one interior angle ⇒ 8x = 1080, ⇒ x = 135°. As n acts as one of the interior angles in this figure ⇒ <em>n = 135 degrees ( ° )</em>

6. Now through supplementary angles, the interior angle adjacent to angle m would form a linear pair, adding to 180°.

7. This would mean that m + interior angle = 180, and as all interior angles were found to be 135 degrees ⇒ m + 132 = 180 ⇒ <em>m = 45 degrees ( ° )</em>

Determine if the function is an even function, an odd function or neither. y=-5x^2-2x+6
Arlecino [84]

Answer:

Neither even nor odd

Step-by-step explanation:

The graph of y = -5x^2 - 2x + 6 is that of a parabola that opens down.  This function is neither even nor odd because a point chosen at random is neither reflected in the y-axis nor reflected in the origin.

Find the volume of the prism.
Rudik [331]

Answer:

216 cubic meters

Step-by-step explanation:

to find the volume of any prism the equation is bh or base times height

the base is a triangle so you find the triangles area and multiply it by the height

8 * 6 * 1/2 = 24

24 * 9 = 216

216 cubic meters

Katie gives Maggie half of her pencils. Maggie keeps 5 pencils and gives the rest to Jamil. A. Write an expression for the numbe
Alexandra [31]

Here's what I mean when I write <em>x/</em><em>2</em><em> </em><em>JUST </em><em>IN </em><em>CASE.</em>

а.

Let the total number of pencils be x, then this implies that Maggie received <em>x/</em>2 pencils from Katie. Maggie keeps 5 and give the rest to Jamil, this means

that Jamil receives

<em>x/</em>2-5 pencils.

b. Expression of pencils given to Jamil is: <em>x/</em>2-5

Substitute <em>x</em><em>=</em><em>1</em><em>6</em><em> </em>in this expression: <em>x/</em>2-5

Simplify and evaluate: = 8-5= 3

Maggie gives 3 pencils to Jamil.

c. Expression of pencils given to Jamil is: x/2-5 to

Equate this expression with 1 to form an equation and solve for <em>x</em> all, the total

number of pencils if Jamil received 1 pencil:

<em>x/</em>2 - 5 = 1

Solve for x:

<em>x</em> = 2(1+ 5)

Evaluate:

<em>x</em> = 2(6) = 12

Katie had 12 pencils if Jamil received 1 pencil.

RESULT

a. Expression of number of pencils given to Jamil is <em>x</em>/2-5, where x is total number of pencils.

b. Maggie gives 3 pencils to Jamil.

c. Katie had 12 pencils if Jamil received 1 pencil.
