Step-by-step explanation:
Put -2 where x is in the function and do the arithmetic. Any number of calculators will compute this for you.
x ≈ 0.23781036584 ≈ 0.2

<em>Comment on the above result</em>
The number above came from the Google calculator (2nd attachment). Surprisingly, it is rounded incorrectly in the last displayed digit. To 20 significant digits, the value is ...
0.23781036584658190876
It appears the Google calculator didn't carry enough digits to get the answer correct in the last displayed decimal place.

Answer:
Minimum - 8.1 inches
Maximum - 8.35 inches
Step-by-step explanation:
The specifications for manufacturing a steel rod stipulate that the length must be 8.225 ± 0.125 inches.
This means that the minimum length must not be 0.125 inches less than 8.225 inches and the maximum length must not be 0.125 inches greater than 8.225 inches.
The minimum length is therefore:
8.225 - 0.125 = 8.1 inches
The maximum length is therefore:
8.225 + 0.125 = 8.35 inches
The sum formula for a geometric sequaence is:
sum(n) = a1(1-r^n)/1-r
Where n is the number of terms, a1 is the first term and r is the common ratio:
s(8) = 3(1-1/2^8) / (1-1/2)
s(8) = 3(1-1/256) / 1/2
s(8) = 2 253/256 / 1/2
s(8) = 765/128
The answer is C.
