Confused on what do do first . Can anyone help ?

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?

In Triangle DEF, the sum of the measures of Angle D and Angle E is 110. The sum of the measures of Angle E and Angle F is 150. F

nevsk [136]

Answer:

<D + <F = $100^{o}$

Step-by-step explanation:

Given: <D + <E = $110^{o}$

<E + <F = $150^{o}$

But, the sum of angles in a triangle = $180^{o}$ .

Thus;

<D + <E + <F = $180^{o}$

$110^{o}$ + <F = $180^{o}$

⇒ <F = $180^{o}$ - $110^{o}$

= $70^{o}$

<F = $70^{o}$

Also,

<E + <F = $150^{o}$

<E + $70^{o}$ = $150^{o}$

<E = $150^{o}$ - $70^{o}$

= $80^{o}$

<E = $80^{o}$

So that;

<D + <E = $110^{o}$

<D + $80^{o}$ = $110^{o}$

<D = $110^{o}$ - $80^{o}$

= $30^{o}$

<D = $30^{o}$

⇒ <D = $30^{o}$ , <E = $80^{o}$ , and <F = $70^{o}$ .

Therefore;

<D + <F = $30^{o}$ + $70^{o}$

= $100^{o}$
