Answer:

Step-by-step explanation:

Given infinite geometric series

1/4, 1/5, 4/25, 16/125, ...

We see that

a = 1/4
r = 4/5

Sum of the series

S = a*1/(1 -r)
S = 1/4*1/(1 - 4/5) = 1/4*1/(1/5) = 1/4*5 = 5/4

What does this mean ---->> 9e+10 please explain the answer

GenaCL600 [577]

This expression can't be solved because we don't know the value of e. Basically what this means is that e, an unknown number, is first being multiplied by 9, and it is then added by 10. You will just leave it as it is.

Answer:

Step-by-step explanation:

Apply Quotient of Powers

$\frac{x {}^{y} }{x {}^{z} } = x {}^{y - z}$

In this questions terms,

$\frac{a {}^{ \frac{1}{3} } }{a {}^{ \frac{1}{4} } } = a {}^{ \frac{1}{3} - \frac{1}{4} }$

$\frac{4}{12} - \frac{3}{12} = \frac{1}{12}$

Which statements are true about the following regular polygon? Check all that apply.

denis-greek [22]

Answer:

2nd one, 3rd one, 4th one(not sure abut this one), 5th one

Step-by-step explanation:

Interior angles of a hexagon is 120 which means it is obtuse not acute

The sum of the interior angles is 720
The polygon cannot/can be divided into three triangles (the internet is saying 6 is possible)
The sum of 2 interior is 240 which is more than the angles of a straight line(180).
