Answer:

a*(1 -0.5)*(1 +0.5) = 0.75a . . . . the original number "a" is larger

(a/(0.75a) -1) * 100% = 33 1/3% . . . . the original number is larger by 33 1/3% of the revised number

Answer:

  • a is larger by 33.33%

Step-by-step explanation:

Initial number = a

<u>Decrease by 50% </u>

  • a - 50% =
  • a - 0.5a =
  • 0.5a

<u>Increase by 50%</u>

  • 0.5a + 50% =
  • 0.5a + 0.5*0.5a =
  • 0.75a

<u>The difference between the initial and final numbers:</u>

  • a - 0.75a = 0.25a

<u>Percent difference:</u>

  • (0.25a/0.75a)*100% = 33.33%

Does (-2)^n/( 3^n+1) converge or diverge?
hodyreva [135]
\left|\dfrac{(-2)^n}{3^n+1}\right|=\dfrac{2^n}{3^n+1}

As n\to\infty, the sequence a_n=\left(\dfrac23\right)^n converges to zero.

If you're talking about the infinite series

\displaystyle\sum_{n\ge0}\dfrac{(-2)^n}{3^n+1}

well we've shown by comparison that this series must also converge because we know any geometric series \sum\limits_n r^n will converge as long as |r|.

Polygon XYZW is dilated by a scale factor of 2 with point T as the center of dilation, resulting in the image X′Y′Z′W′. If point
Anettt [7]
Since the whole figure including all the points is enlarged at the same time, the dilated figure will still have the same slope and that includes the fact that point T is still in line Y'Z'. The slope or shape does not change, only the size alters.The center of dilation is still at Point T in this case.
