Its d 729 because on 1 layer theres are 81 cubes and there are 9 layers so 81 times 9 equals 729
Hope this helps
Answer B. there are any restrictions. You can represent it in any x point
Answer:
The answer depends on what the problem really is.
f(1/2) = 8
or
f(1/2) = 4
See below.
Step-by-step explanation:
This is the problem as it was posted:
y = f(x) = 16x
Let x = 1/2
y = f(1/2) = 16(1/2) = 8
Perhaps the problem is this:

If x is an exponent of 16 and not a factor, then the answer is:

Sec x and cot x are the reciprocals of cos x and tan x respectively.
So, for example, cos x = adj / hyp, so sec x = hyp / adj
The last choice is the correct one because tan x = opp / adj so cot = adj / opp.
A) False
B) False
C) True
