n is the number of sides

In this problem

n=5

substitute

5(5-3)/2=5\ diagonals

see the attached figure to better understand the problem

Please help me with 1,2,3,4,5,6,7,8,9 tell me how u get it and the answer please I really need help
NNADVOKAT [17]

Answer:

1) x = 15

Step-by-step explanation:

We use the Pythagorean thm for these questions. Where a and b are the legs (So order doesn't matter), and where c is the hypotenuse

1)

a² + b² = c²

9² + 12² = x²

81 + 144 = x²

x² = 225

You square root each side so you can get rid of the exponent on x.

\sqrt{x^2} =\sqrt{225}

x = 15

Is 9.373 a repeating? is it rational?
kow [346]

Decimal numbers are repeating if the part after the decimal separator never ends, but has a cicle. For example, 14.020202020202.... is a repeating decimal number, because after the decimal separator you can see a pattern: 02 repeated indefinitely.

In your case, the part after the decimal separator is finite: there is no repeating part. Every number with a finite decimal part is rational. In your case, the number 9.373 can be written as the fraction

\dfrac{9373}{1000}

which proves that the number is rational.
