Please, I need help I'm way behind.
gregori [183]

Answer:

\frac{18√2}{√3}

Step-by-step explanation:

  1. The lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3.
  2. The lengths of the sides of a 45-45-90 triangle are in the ratio 1 : 1 : √2
  3. We can get the length of the longest side of the bottom triangle is 9×2÷√3 = \frac{18}{√3}
  4. And based on the theory shown on the 2nd step, we can get x (the length of the longest side of the upper triangle) is \frac{18}{√3}x√2

If 205 is a posible answer I think thats's it
Because it's just like multiplucation 41x1=41
                                                        42x2=82.......etc.
                                                       42x5=205

Which geometric series converges?
kvv77 [185]

Answer:

Option (1)

Step-by-step explanation:

In a geometric series,

\sum_{n=0}^{\infty}ar^n=a+ar^1+ar^2+....

Here r = \frac{a_n}{a_{n-1}}

For |r| < 1, series will converge.

For |r| > 1, series will diverge.

Option (1)

Given geometric series is,

\frac{1}{2}+\frac{1}{4}+ \frac{1}{8}+ \frac{1}{16}.......

Common ratio = \frac{\frac{1}{4}}{\frac{1}{2} }

                        = \frac{1}{2}

Since, \frac{1}{2}

Series will converge.

Option (2)

\frac{1}{2}+1+2+4+......

r = \frac{1}{\frac{1}{2}}=2

Since, 2 > 1,

Series will diverge.

Option (3)

\frac{1}{2}+ \frac{3}{2}+ \frac{9}{2}+ \frac{27}{2}+......

Common ratio 'r' = \frac{\frac{3}{2} }{\frac{1}{2} }=3

Since, 3 > 1,

Series will diverge.

Option (4)

\frac{1}{2}+3+18+108+.....

Common ratio 'r' = \frac{3}{\frac{1}{2}}=6

Since, 6 > 1

Series will diverge.

Therefore, Option (1) will be the correct option.
