A geometric series has second term 375 and fifth term 81 . find the sum to infinity of series .

Eduardwww [97]

Answer: $\bold{S_{\infty}=\dfrac{3125}{2}=1562.5}$

Step-by-step explanation:

a₁, 375, a₃, a₄, 81

First, let's find the ratio (r). There are three multiple from 375 to 81.

$375r^3=81\\\\r^3=\dfrac{81}{375}\\\\\\r^3=\dfrac{27}{125}\qquad \leftarrow simplied\\\\\\\sqrt[3]{r^3} =\sqrt[3]{\dfrac{27}{125}}\\ \\\\r=\dfrac{3}{5}$

Next, let's find a₁

$a_1\bigg(\dfrac{3}{5}\bigg)=375\\\\\\a_1=375\bigg(\dfrac{5}{3}\bigg)\\\\\\a_1=125(5)\\\\\\a_1=625$

Lastly, Use the Infinite Geometric Sum Formula to find the sum:

$S_{\infty}=\dfrac{a_1}{1-r}\\\\\\.\quad =\dfrac{625}{1-\frac{3}{5}}\\\\\\.\quad =\dfrac{625}{\frac{2}{5}}\\\\\\.\quad = \dfrac{625(5)}{2}\\\\\\.\quad = \large\boxed{\dfrac{3125}{2}}$

The carpet used in Parkers bedroom covers an area of 121 square feet. If the carpet is square, what is the length of each side o

steposvetlana [31]

The length of the carpet's side is 11 feet

Step-by-step explanation:

Step 1 :

The area covered by the carpet = 121 square feet

We need to find the length of side of carpet

Step 2 :

Since it is given that the carpet is square, the length of all sides are the same

The area is obtained by squaring the side. Hence to find the side from the given area we need to take the root of the area.

Side² = 121

Therefore side = √121 = 11 feet

Step 3 :

Answer :

The length of the carpet's side is 11 feet
