Answer:
3.31
Step-by-step explanation:
√11 = 3.31662479 so we're looking for the nearest <em>hundredth</em> so the hundredths place is two places after the decimal, we land on the 1 so we look and see the answer is 3.31

Answer:
1. x^4 -x^3 -4x^2 -3
a1 = -7.4
an = an-1 -13.8 (choice 1)
Step-by-step explanation:
f(x) = x^4 -x^2 +9
g(x) = x^3 +3x^2 +12
We are subtracting
f(x) -g(x) =x^4 -x^2 +9 - ( x^3 +3x^2 +12)
Distribute the minus sign
x^4 -x^2 +9 - x^3 -3x^2 -12
I like to line them up vertically
x^4 -x^2 +9
- x^3 -3x^2 -12
-------------------------
x^4 -x^3 -4x^2 -3
2. a1 = -7.4
To find the common difference, take term 2 and subtract term 1
-21.2 - (-7.4)
-21.2 + 7.4
-13.8
an = an-1 -13.8
From the constraint, we have
so that 
depends only on 
.
Find the critical points of 
.
Using the given constraint again, we have the condition
so that
and depends only on 
.
Find the critical points of 
.
It follows that 
and 
, so the only critical point of is at (3, 3, 3).
Differentiate again and check the sign of the second derivative at the critical point.
for all , which indicates a maximum.
We find that
