Two children are sitting on a seesaw that is 12ft long. One child weighs 60lb. The other child weighs 90lb. How far from the 90-

jeyben [28]

Answer:

Step-by-step explanation:

moments about the fulcrum should be equal

IF x is the distance of the fulcrum from the 90 lb child

90[x] = 60[12 - x]

90x = 720 - 60x

150x = 720

x = 4.8 ft

90(4.8) = 432 ft•lb

60(12 - 4.8) = 432 ft•lb

Find the interval of convergence of the power series. (Be sure to include a check for convergence at the endpoints of the interv

Anon25 [30]

I'm guessing the power series given is

$\displaystyle \sum_{n=1}^\infty (-1)^{n+1}\frac{(x-8)^n}{8^n}$

which you can condense somewhat into

$\displaystyle -\sum_{n=1}^\infty \left(\frac{8-x}8\right)^n$

You should recognize this as a geometric series, which converges for

$\left|\dfrac{8-x}8\right|$
