Confused on what do do first . Can anyone help ?

kirza4 [7]

So solve for q

first factor q out of the summation $q \sum^{\inf}_{k=2} (\frac{2}{3})^k=8$

now, determine what the summation is
$\sum^{\inf}_{k=2} (\frac{2}{3})^k =?$

its been a while since ive done summations so i dont remember any tricks but that summation is essentially equal to
$\frac{2}{3} ^2 +\frac{2}{3}^3+\frac{2}{3}^4+\frac{2}{3}^5+...$

or factored to be something like this
$\frac{2}{3}^2 *(1+\frac{2}{3}+\frac{2}{3}^2+\frac{2}{3}^3+...)$
which i believe there's a formula for

regardless using a calculator, the summation turns out to be 4/3 i think

you should definitely double check this step

so replacing the summation for 4/3, the equation is now
q*(4/3) =8

pretty easy to solve from here
divide 4/3 to both sides to get q

any questions?

Crystal wants to add the fractions 1/16 and 3/18 what is the lowest common denominator of the two fractions?

zhenek [66]

Answer:

288

Step-by-step explanation:

First, simplify the fraction 3/18 to 1/6, this will help a lot. Then, you just, find the LCM, and you can list out the mutliples to help you

6, 12, 18, 24, 39, 36, 42, 48, 54, 60

16, 32, 48, 64, 80

It would be easiest to do 48

But that's not exactly what the question is asking

It's asking the LCM of 1/16 and 3/18

I wanted to show you the other way so you would be able to think of it in a different way which would be easier

You would just list out the multiples again.

18, 36, 54, 72, 90, 108, 126, 135, 153, 171, 189

16, 32, 48, 64, 80, 96, 112, 130, 146, 162, 178, 194

Ok, I give up on that

Let's just do 16*18 which is 288.

288 is your LCM

Sometimes multiplying is easier and other times listing it out is easier.

I hope this helped

Let me know if you have any questions
