Use the formula for geometric sequences:
=
Substitute 1 in for , -1/3 in for r, and 9 in for n
=(1)(-1/3^9-1)
=(1)(-1/3^8)
=(1)(0.00015241579)
=0.00015241579

Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
- <em>There is a formula for estimating square root of non-perfect square numbers</em>
- <em>√(A²±B) = A ± B/2A</em>
- <em>where A² is the nearest perfect square, B is the difference between the original number and the perfect square</em>
<u>Examples</u>
- 1) √75 = √(8²+11) = 8 + 11/(2*8) = 8 + 11/16 = 8.6875
- 2) √114 = √(11² - 7) = 11 - 7/(2*11) = 10.6818
