Which polygon is a concave octagon?

Mathematics
2 answers:
Bezzdna [24]2 years ago

The polygon in option 3 is not octagon at all, it is heptagon (or 7-sided polygon).

A convex octagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°.

When some internal angle is greater than 180°, it is concave.

In option 2 you can see that one angle is pointing inward, then this octagon is concave.

Answer: correct choice is B.

Olin [163]

Answer:

Your bi-weekly deposit is $404.54.

Step-by-step explanation:

At a $8.60 per hour wage for 32 hours per week, your gross pay each week is $275.20, or $550.40.  However, your deductions and tax withholdings total 26.5% taken from your gross pay.  Multiplying $550.40 by 26.5%, or .265, is a total of $145.86.  Your realized income, or what you will make after taxes, would be $550.40-$145.86 = $404.54.  So, every two weeks, or bi-weekly, your direct deposit would be in the amount of $404.54.

The answer would be: 13^3.

This is because 2-4= -2
Then you add -2 to 5 and you would get 3. So the exponent is 3.
I hope this helps :)

Well we know that...a^{-1}=\frac{1}{a^{1} }\\.

So...(\frac{1}{5})^{-1}=\frac{1}{\frac{1}{5}^{1}}=5\\\\.

Because 5^{3}=125,

\frac{1}{5}^{-1*3}=125\\  x=-1*3=-3

answer: -3
