The answer is 5:2 ration, it's already fully simplified
Do 2/7+3/5 and you have your answer. 2/7+3/5=10/35+21/35=31/35.
Answer:
q = 9
Step-by-step explanation:
the key thing to understand in this problem is the distributive property. which basically means we can muliply what's on the interior of the parenthestes ( in this case q-5) by what's on the outside (4).
so 4 will <em>distrubute</em> to both the q and the -5
4q - 20 = 16
add 20 to both sides
4q = 36
divide both sides by 4
q = 9

Here is the full question:
Find the sum of the convergent series by using a well-known function. (Round your answer to four decimal places.) Σ_(n=1)^∞ (-1)^n+1 1/7^n n
Step-by-step explanation:
Σ_(n=1)^∞ (-1)^n+1 1/7^n n
We will use the function In (1 + x)
We will now give a power series expansion of the function while it is centered at x=0
This will give us In (1 + x) = Σ_(n=1)^∞

Note that x= 1/7
Now let us equate the two equations
Σ_(n=1)^∞
= ㏑(1 + x)|
= ㏑
Sum of the series will give ㏑
