Use the comparison test to determine whether the series is convergent or divergent

Lunna [17]

Answer:

b) diverges

Step-by-step explanation:

Given is a series with the terms

$\frac{25}{3} +\frac{125}{9} +\frac{625}{27} +...$

We find that this series follows a pattern such that each term is multiplied by 5/3 to get the next term.

In other words, this is a geometric series with I term=25/3 and common ratio=5/3

Sum of geometric series upto n terms

= $\frac{a(r^n-1}{r-1} =\frac{25}{3} (\frac{(\frac{5}{3} )^n-1}{\frac{5}{3}-1 } )\\$

Since r>1, we find that this series diverges to infinity

Hence answer is

B) divergent

Evaluate the expression when a= 4, b= - 2, and c= 7 - -> 5a - 9 (b - c)

ollegr [7]

Answer:

$65$

Step-by-step explanation:

Given the following question:

$5a-9(b-c)$
a = 4
b = 2
c = 7

In order to find the answer, we need to substitute the variables with the numbers given, and then solve using PEMDAS.

$5\times4-9\times(2-7)$
$2-7=-5$
$5\times4-9\times-5$
$5\times4=20$
$20-9\times-5$
$9\times-5=-45$
$20--45$
$20+45=65$
$=65$

Hope this helps.
