Find the sum to n terms of the series 0.6+0.66+0.666+.....................

RSB [31]

We have
 $0.6+0.66+0.666+0.6666$

Let's take 6 out from the series
$6(0.1+0.11+0.111+0.1111+....$

Now multiply and divide by 9
 $\frac{6}{9}(0.9+0.99+0.999+0.9999+....$

$\frac{6}{9}(1-0.1+1-0.01+1-0.001+1-0.0001+....
\\
\\\frac{6}{9}(1-10^{-1}+1-10^{-2}+1-10^{-3}+...$

all 1s add up to n
 $\frac{6}{9}(n-\frac{1}{10}\times \frac{1-(\frac{1}{10})^{n+1}}{1-\frac{1}{10}})$

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=70°, and OM = 3.3 feet. Find the length of MN to the nearest tenth of a foot.

Aleks04 [339]

Answer:

Side MN = 3.5

Step-by-step explanation:

Side NO = 1.2011

Side OM = 3.3

Side MN = 3.51179

Angle ∠M = 20° = 0.34907 rad = π/9

Angle ∠N = 70° = 1.22173 rad = 7/18π

Angle ∠O = 90° = 1.5708 rad = π/2
