What expression is equivalent to a^m divided by a^n?

1 answer:

4 0

$a^m=\underbrace{a\cdot a\cdot a\cdot...\cdot a}_m\\\\a^n=\underbrace{a\cdot a\cdot a\cdot...\cdot a}_n\\\\a^m:a^n=\dfrac{a^m}{a^n}=\dfrac{\overbrace{a\cdot a\cdot a\cdot...\cdot a}^m}{\underbrace{a\cdot a\cdot a\cdot...\cdot a}_n}=a^{m-n}\\\\\boxed{a^m:a^n=a^{m-n}}$

What is the value of x?<br> 6<br> 8<br> 010<br> O 12

Morgarella [4.7K]

Answer:

Step-by-step explanation:

The sum of the internal angles of a polygon is

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

here n = 5, hence

sum = 180° × 3 = 540°

Each exterior angle plus interior angle = 180°

Subtract each exterior angle from 180 for corresponding interior angle.

180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118

Sum the 4 interior angles and subtract from 540 for 5 th interior angle

5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°

The 5 th interior angle and 12x sum to 180 ( same reason as above )

Hence

12x + 84 = 180 ( subtract 84 from both sides )

12x = 96 ( divide both sides by 12 )

x = 8

Which graph represents g(x)=−(x−3)2−5 ?

tia_tia [17]

Answer:

see below

Step-by-step explanation:

The leading minus sign tells you the graph opens downward. (x-3) in the squared term tells you the x-coordinate of the vertex is x=3. The graph that matches these characteristics is shown below.
