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}

<u>Step-by-step explanation:</u>

  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}}

Find the length of side x in simplest radical form with a rational denominator.
mr Goodwill [35]

Answer:

\sqrt{6}

Step-by-step explanation:

\sin \: 45 \degree =  \frac{ \sqrt{3} }{x}  \\  \\  \frac{1}{ \sqrt{2} }  =  \frac{ \sqrt{3} }{x}  \\  \\  x =  \sqrt{2}  \times  \sqrt{3}  \\  \\ x =  \sqrt{2 \times 3}  \\  \\ x =  \sqrt{6}

The eastern continental trail is 15 times longer than the Erie canal way trail. The combined length of the hiking trails is 5,76
Lena [83]

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

Step-by-step explanation:

Given,

Combined length of both trails = 5760 miles

Let,

x be the length of eatern continental trail.

y be the length of Erie canal trail.

According to given statement;

x+y=5760     Eqn 1

x = 15y          Eqn 2

Putting value of x from Eqn 2 in Eqn 1

15y+y=5760\\16y=5760

Dividing both sides by 16

\frac{16y}{16}=\frac{5760}{16}\\y=360\\

Putting y=360 in Eqn 2

x=15(360)\\x=5400

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.
