Let A (101, 202, 303, 404, 505) and B (101, 404). What is A n B?
Zepler [3.9K]
You should use curly braces instead of parenthesis to indicate set notation. The answer is {101, 404} as these two values are in both set A and set B at the same time. The upside down U symbol means "intersection" which is where the two sets overlap. In terms of a Venn Diagram, you'll have two overlapping circles. In the overlapping region is where 101 and 404 are written. In the region of circle A that is outside of B, you'll have 202, 303, and 505. There is nothing to write in the region of B that is outside of A (since all of B is inside A)

Once again, the answer is {101, 404}

Find the measure of one interior angle in each regular polygon. Round your to nearest tenth if necessary.
e-lub [12.9K]

The value of the interior angle of the regular polygon is calculated using the formula (n - 2) 180 / n where n is the number of sides of the regular polygon.

<u>Step-by-step explanation:</u>

A regular polygon refers to a multi-sided convex figure where all the sides are equal in length and all the angles have equal degree measures.

The triangle has 3 interior angles of  60  degrees

The square has 4 interior angles of  90  degrees.

The pentagon has 5 interior angles of  108  degrees  .

The formula for the interior angle of a regular polygon is given by,

                            ( n − 2 ) 180  /  n

where n refers to the number of sides.

Triangle : (3 - 2) 180 / 3 = 60 degree.

Square : (4 - 2) 180 / 4 = 90 degree.

Pentagon: (5 - 2) 180 / 5 = 108 degree.

What is the quotient?
Butoxors [25]

Answer: FIRST OPTION

Step-by-step explanation:

According the quotient of powers property, when you have the division of two powers with the same base, then you must subtract the exponents.

Therefore, keeping the property above on mind, you have that the quotient is the shown below:

\frac{(-7)^2}{(-7)^{-1}}=(-7)^{(2-(-1))}=(-7)^{(2+1)}=(-7)^3=-343
