The radius of a circle is half the length of the circumference.
So multiply 12 by itself and you get 24.
The answer is C.
Bring like terms together
(REMEMBER CHANGE THE SIGN WHEN MOVING ACROSS THE EQUAL SIGN i.e. - becomes + and + becomes -)
4x - 2x = 7 - 3
2x = 4
divide both sides by 2
x = 2
Answer:
-2x^2-11x^3
Step-by-step explanation:
T=0.33c+32
0.33c=0.33×c: cost of the additional cards
(g o f)(2x)=g(f(2x))
take derivitive
use chain rule
remember
derivitive of g(f(x))=g'(f(x))f'(x)
so
g(f(2x))=g'(f(2x))f'(2x)(2)
at x=1
f(2x)=f(2)=1
g'(1)=1
f'(2x)=f'(2)=1
we get
(1)(1)(2)=2
it is 2
I hope yo udidn't copy the wrong value for f(x) or f'(x)
