What is the sum of an 8-term geometric series if the first term is −11, the last term is 859,375, and the common ratio is −5? −1

LekaFEV [45]

Answer:

The sum of geometric series is 716144

Step-by-step explanation:

Given

First term=a_1= -11

Last term=a_8=859375

Common ration of geometric series=r= -5

And

Total terms in geometric sequence=n=8

We know that the formula for sum of geometric series is:

S_n= (a_1 (1-r^n))/(1-r)

= (-11(1-(-5)^8)/(1-(-5))

= (-11(1-5^8))/(1+5)

= (-11(1-390625))/6

=(-11(-390624)))/6

=4296864/6

=716144

So the sum of geometric series is: 716144 ..

Tap A fills a tank in 4hours while B fills the same tank in 3hours. Tap C empties this tank when full in 2hours. If the tank is

boyakko [2]

Answer:

<em>It will take 12 hours to fill the tank</em>

Step-by-step explanation:

Proportions

Tap A fills a tank in 4 hours. It means each hour it fills 1/4 of the tank.

Tap B fills the tank in 3 hours. Each hour it fills 1/3 of the tank.

Tap C empties the tank when full in 2 hours. Each hour it empties 1/2 of the tank.

Each hour, the tank gets filled by:

$\displaystyle \frac{1}{4}+\frac{1}{3}-\frac{1}{2}=\displaystyle \frac{3}{12}+\frac{4}{12}-\frac{6}{12}=\frac{3+4-6}{12}=\frac{1}{12}$

Since the tank fills 1/12 of its capacity in one hour, it follows that it will take 12 hours to fill the tank
