so we're considering the level curve

The tangent line to this curve at (2, -1) will be the value of

at this point. Differentiating yields

and so the slope of the tangent would be

.
The tangent line then has equation
Answer:
a5=445
Explanation:
a of n=(a+1)*n
a1=2
I found the pattern to add 1 to the previous number and then multiply it by its number in the sequence. Apologies for the terrible format of my recursive formula.
Proof of pattern:
(2+1)*2=6
(6+1)*3=21
(21+1)*4=88
a5=(88+1)*5=445
I think it k < -32 pretty sure
Answer:
5
Step-by-step explanation:
Simplify
(5 1/3)^3=?
Solution:
Using Identity
(x^a)^b=x ^(a*b)
So in the given expression
x=5
a=1/3
b=3
Therefore,
(5 1/3)^3= 5 (1/3*3)= 5^1=5
Therefore,
(5 1/3)^3=5
