Answer:
Step-by-step explanation:
We are given the following in the question:
Keith has $100 in a savings account at the beginning of the summer.
Let x be the number of weeks he works.
He makes $25 each week at his babysitting job.
He wants to earn more than $350 dollars during summer.
Total money earned by job =
His total money in account should be more than 350$.
We can write this with the help of inequality:
The following inequality represents the given situation.
The sum of the infinite geometric series is -288.
<h2>Given that</h2>A finite geometric series with n = 4, a₁ = -144, and r = ½.
<h3>We have to determine</h3>What is the sum of the infinite geometric series?
<h3>According to the question</h3>The sum of the infinite is determined by the following formula;
A finite geometric series with n = 4, a₁ = -144, and r = ½.
Substitute all the values in the formula;
Therefore,
The sum of the infinite geometric series is,
Hence, the sum of the infinite geometric series is -288.
