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?

Camden is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 5 points. What would

serg [7]

Answer:

40/50

Step-by-step explanation:

The test is worth 50 points in total. Each question is worth 5 points. So,

50 points ÷ 5 points each = 10 questions

If he gets 2 questions wrong,

10 - 2 = 8

He got 8 out of 10 questions right.

Now, multiply by 5 to find his test score out of 50.

8 × 5 ÷ 10 × 5

= 40/50

His test score would be 40/50.

Hope that helps.

Answer:

x=30

Step-by-step explanation:

So we know that a shape with 4 angles equal 360 degrees and this has 4 angles. Since we know that 4x is one and 2x is one We cna use the vertical angles to find the other two. Since 4x is opposite of an unknown side it is also 4x becuase vertical angles are equal becuase they are opposite sides of each other. Same thing with 2x

Now add them all up

4x+4x+2x+2x which will equal 12x

now 12x=360

x=30
