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 ..

The inequality is given by 20x + 25y ≤ 1100 and x + y > 50

<h3>What is an inequality?</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let y represent the number of soccer balls and x represent the number of volleyballs.

The coach can spend a maximum of $1,100, hence:

20x + 25y ≤ 1100

Also, The coach plans to order at least 50, hence:

x + y > 50

The inequality is given by 20x + 25y ≤ 1100 and x + y > 50
