Area of regular polygons
Finger [1]
Hello!

To find the area of a hexagon you do 3\frac{3 \sqrt{3} }{2} } a^{2} where a is one of the sides

Since the perimeter is 60 we can do 60/ the sides of the shape

60/6 = 10

So one side is equal to 10

you put that into the formula to get the area of a hexagon and you get 259.81

Hope this helps!

Write the nth term of the following sequence in terms of the first term of the sequence.
vovikov84 [41]

Givens

Sequence 2, - 4, 8, -16, 32 ....

First term = a = 2

Problem

Find the nth term

tn = (-1 )^(n -1) * (a)^n answer or

tn = (-1)^(n - 1) * 2^n

where a is defined as the first term (it usually is given that designation).

Try a few to make sure the formula is correct

<em>n = 1</em>

t1 = (-1)^(1 - 1) * 2^1

t1 = (-1)^0 * 2

t1 = 1 * 2 = 2

<em>n =2</em>

t2 = (-1)^(2 - 1) * 2^2 = (-1)^1 * 4 = -4

What is 2.318 repeating as a mixed number?
ioda
The idea being, we first, move the repeating part to the left of the decimal point, by simply multiplying it by a power of 10, in this case, we need to move 318, so we need then 1000, 3 decimals, 3 zeros.

and we'll make the expression a variable, so let's do so first,

\bf \boxed{x=2.318318\overline{318}}\\\\&#10;-------------------------------\\\\&#10;\begin{array}{llll}&#10;1000\cdot x&=&2318.318\overline{318}\\&#10;&&2316+2.318318\overline{318}\\&#10;&&2316+x&#10;\end{array}\implies 1000x=2316+x&#10;\\\\\\&#10;999x=2316\implies x=\cfrac{2316}{999}\implies x=\cfrac{772}{333}\implies x=2\frac{106}{333}
