what are the possible lengths and widths of a rectangle if its length is 8 centimeters longer then the width and the area is les

Ierofanga [76]

If the Length is 11 and the Width is 3 that makes the area 33. Now if you want all possible answers less than 33 then:
L: W: A:
11cm 3cm = 33cm
10cm 2cm = 20cm
9cm 1cm = 9cm

Now that's as low as you can get with whole numbers.

Find S5 for a geometric series for which a1=81 and r=1/9.

Minchanka [31]

ANSWER

$S_5=91\frac{10}{81}$

EXPLANATION

The sum of the first $n$ terms of a geometric sequence is given by;

$S_n=\frac{a_1(1-r^n)}{1-r} ,-1$

Where $n$ , is the number of terms and $a_1$ is the first term.

When $n=5$ , we have $a_1=81$ , we get;

$S_5=\frac{81(1-(\frac{1}{9})^5)}{1-\frac{1}{9}}$

$S_5=\frac{81(1-\frac{1}{59049})}{1-\frac{1}{9}}$

$S_5=\frac{81(\frac{59048}{59049})}{\frac{8}{9}}$

$S_5=\frac{7381}{81}$

$S_5=91\frac{10}{81}$
