Rational Number - Any number that can be written as a fraction.
Prime Number - Is a number that it's only factor is 1 and itself.
----------------------------------------------
Solution and Answer:
15/17 ≈ 0.88
15/17 cannot be simplified because 17 is a prime number and both numbers don't have common prime factors.

I believe the answer are as follows: 1. A 2. B 3. A 4. D 5. B and 6. B
Answer:

Step-by-step explanation:
Rn(x) →0
f(x) = 10/x
a = -2
Taylor series for the function <em>f </em>at the number a is:

............ equation (1)
Now we will find the function <em>f </em> and all derivatives of the function <em>f</em> at a = -2
f(x) = 10/x f(-2) = 10/-2
f'(x) = -10/x² f'(-2) = -10/(-2)²
f"(x) = -10.2/x³ f"(-2) = -10.2/(-2)³
f"'(x) = -10.2.3/x⁴ f'"(-2) = -10.2.3/(-2)⁴
f""(x) = -10.2.3.4/x⁵ f""(-2) = -10.2.3.4/(-2)⁵
∴ The Taylor series for the function <em>f</em> at a = -4 means that we substitute the value of each function into equation (1)
So, we get
Or 
The answer is 1/3 is the answer.
You could use a simple calculator it's only 10.
