Answer:
It should be 46.20
Step-by-step explanation:
You're rounding to the nearest hundredth. So you have 46.1979 to start out with. Then you count 2 places so you end at the 1st 9. Well, behind the 9 is a 7 so you round up and get 20
I do not understand what you are asking but I am going to assume that you are trying to simplify the equation.
First, write the equation.
(4/3)b + 2 = 4 - (1/3)b
Add (1/3)b to each side.
(5/3)b + 2 = 4
Subtract 2 on each side.
(5/3)b = 2
Divide by (5/3) on each side
b = 1.2
b = 1.2 is your final answer.

I don't understand the language you used
True.

We wrote it in the form dy/dx = g(x) f(y) so this is separable.
Answer:
Step-by-step explanation:
Unclear. Did you mean f(x) = 2^(x + 3)? If so, the parentheses are mandatory.
Assuming that f(x) = 2^(x + 3) is correct, then:
a) f(2) = 2^(2 + 3) = 2^5 = 32
b) f'(x) = 2^(x + 3)*(x + 3)' = 2^(x + 3)(1) = 2^(x + 3)
c) f"(x) = 2^(x + 3) (same as in (b)), so that:
f"(12) = 2^15
