$\frac{1}{3}$ ÷ 2
Multiply by the reciprocal:
$\frac{1}{3}$ × $\frac{1}{2}$
This leads us to an answer:

Lnx=-3

scZoUnD [109]

Answer:

because It's rounded to the nearest hundred place

Step-by-step explanation:

Given equation:

$\ln(x ) = - 3$

recall that,

$\ln(a ) = b \iff {e}^{b} = a$

remember, In is natural logarithm which is actually nothing but common logarithm with the base euler's number (e) . anyway rewriting lnx=-3 yields:

$\ln( x ) = - 3\\ \iff {e}^{ - 3} = \frac{1}{ {e}^{3} }$

1/e³ is approximately 0.0497870684..... , rounding it to the nearest hundred place would be 0.05 which is the same answer as your textbook .

Find the oth term of the geometric sequence 9, -18, 36, ...

Sphinxa [80]

Answer:

2304

Step-by-step explanation:

Given :-

A geometric sequence is given to us which is 9 , -18 , 36.

And we need to find out the 9th term of the sequence. Here firstly we should find the Common Ratio and then we can substitute the respective values in the formula to find the nth term of a geometric sequence .

Common Ratio :-

$:\implies$ CR = -18÷ 9 = -2

The 9 th term :-

$:\implies$ T_n = arⁿ - ¹

$:\implies$ T_9 = 9× (-2) ⁹ - ¹

$:\implies$ T_9 = 9 × (-2)⁸

$:\implies$ T_9 = 9 × 256

$:\implies$ T_9 = 2304

Hence the 10th term is 2304.
