Answer:
Step-by-step explanation:
a)
Substitute limits to get
=
Thus converges.
b) 10th partial sum =
=
c) Z [infinity] n+1 1 /x ^4 dx ≤ s − sn ≤ Z [infinity] n 1 /x^ 4 dx, (1)
where s is the sum of P[infinity] n=1 1/n4 and sn is the nth partial sum of P[infinity] n=1 1/n4 .
(question is not clear)
Answer:
it ain't
Step-by-step explanation:
x = -8
y = 2
-(-8) - 2(6) > 12
8 - 12 > 12
-4 > 12
This is incorrect
I did not understand quite well, but I am assuming two possibilities, I hope it will be helpful.
If you meant what is the result 4x^2-6 if x equals to 3:
4(3)^2-6
12^2-6
144-6
=138
If you meant 4x(2)-6
4(3)(2)-6
12(2)-6
24-6
=18
Hope I could help!
Answer:
always stick to this order
PEMDAS
Parentheses
exponent
multiplication/division
Addition/subtraction
by that you'll start by
adding 6+3+1 = 10
then power 2 equals 100
then multiply by 1/4
gives you 100/4 = 25
