Rational expressions are bascially an expression where one polynomial is divided by another. And a polynomial is a series of terms like ax^b added together, where the exponents, what I labeled as b, need to be positive integers.

give an example of a convergent infinite series whose sum equal 3/5. explain how you know your series converges and write out wo

krek1111 [17]

Answer:

The series 1/5, 2/15, 4/45, 8/135... converges and sums up to 3/5

Step-by-step explanation:

Consider the infinite geometric series

1/5, 2/15, 4/45, 8/135...

With first term, a=1/5

common ratio, r = ⅔

The series converge because the common ratio, |r|<1.

The sum to infinity of a geometric series, S= a/(1-r)

S= 1/5 ÷ (1-⅔) = 1/5 ÷ 1/3 = 3/5

Therefore, the geometric series 1/5, 2/15, 4/45, 8/135... sums up to 3/5.

2a+3b=5? What is that someone please help ASAP !!

AnnyKZ [126]

Answer:

subtract 2a + 3b - 3b =5 - 3b

simply 2a = 5 -3b

divide both sides by 2 . 2a over 2 = 5 over 2 - 3b over 2

simply a= 5- 3b over 2
