Answer:

900 °

Step-by-step explanation:

A heptagon is a 7-sided polygon with 7 interior angles that sum to 900 °. The name heptagon derives from the Greek words hepta- for seven and -gon for sides. A heptagon is also called a 7-gon or septagon ( septa- is Latin for seven).

The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180°. Where n is number of sides.

Find four geometric means between 25 and 800.

SVEN [57.7K]

Actually, you have to find four missed terms of geometrical sequence. Denote

$a_1=25,\\ a_6=800$

and r - ratio, then

$a_2=a_1\cdot r=25r,\\a_3=a_1\cdot r^2=25r^2,\\a_4=a_1\cdot r^3=25r^3,\\a_5=a_1\cdot r^4=25r^4,\\a_6=a_1\cdot r^5=25r^5$ .

Since $a_6=800$ , you have that $800=25r^5$ , then

$r^5=\dfrac{800}{25} =32,\\r=2$ .

Now substitude r=2 in each of unknown 4 terms:

$a_2=25\cdot 2=50,\\a_3=25\cdot 2^2=100,\\a_4=25\cdot 2^3=200,\\a_5=25\cdot 2^4=400$ .

Answer: four geometric means between 25 and 800 are 50, 100, 200, 400.

Help what polynomials are there??

N76 [4]

Answer:

All of them are polynomials except c.

Step-by-step explanation:

Polynomials are in the form:

$a_0+a_1x+a_2x^2+a_3x^3+a_4x^4+a_5x^5+a_6x^6+\cdots +a_nx^n$

You can see here there are no extra symbols like square root, cube root, absolute value, and so on on the variable x...

We also don't have division by a variable. All the exponents are whole numbers.

a) While it has a square root, it is not on a variable so a is a polynomial. The exponents on the variables are whole numbers.

b) b is a polynomial also because all the exponents are whole numbers.

c) This is not a polynomial because there is a square root on a variable.

d) This is a polynomial. All the exponents are whole numbers.

Can someone help (will give brainliest)

nikklg [1K]

Answer:

384

Step-by-step explanation:

8 x 6 = 48

48 x 2 = 96

12 x 10 = 120

6 x 12 = 72

8 x 12 = 96

96 + 120 + 72 +96 = 384
