Since our unknown number is x and also we are creating an equation, the eight much less than a number will be ~ above one side where the number is x, and on the various other side is 10. So,10=2x-8

Identify even if it is the series sigma notation infinity i=1 15(4)^i-1 is a convergent or divergent geometric series and uncover the sum

**sdrta.net: The correct option is **

**(d) This is a divergent geometric series. The sum cannot be found.You are watching: When constructing a perpendicular bisector why must**

**Step-by-step explanation: **The offered infinite geometric series is

We room to determine whether** the given geometric collection is convergent or divergent. If convergent, we room to discover the amount of the series.**

We have the **D" Alembert"s ratio test**, claims as follows:

Let,

is an infinite series, with complex coefficients and we consider the complying with limit:Then, the series will it is in **convergent if l 1.**

**For the provided series, we have**

**So, the border is offered by**

**1." alt="L\\\\\\=\lim_i\rightarrow \infty\dfraca_i+1a_i\\\\\\=\lim_i\rightarrow \infty\dfrac15(4)^i15(4)^i-1\\\\\\=\lim_i\rightarrow \infty\dfrac15(4)^i15(4)^i4^-1\\\\\\=\dfrac14^-1\\\\=4>1." align="absmiddle" class="latex-formula">**

**Therefore, together >1, and also so the given collection is divergent and also hence us cannot discover the sum.**

**Thuds, (d) is the exactly option.See more: Can You Use Margarine Instead Of Butter In Cookies ? Margarine Or Butter**
