Answer:
Explanation:
g(x) = f(x + 1) - 2
g(x) = (x + 1 + 3)^3 -2
g(x) = (x + 4)^3 - 2
Now what are we supposed to do with this? I'm guessing we are to find what value of x will make g(x) = 12. If I'm wrong, leave a note in the form of a comment.
g(x) = 12
(x + 4)^3 - 2 = 12 Add 2 to both sides.
(x + 4)^3 = 14 Take the cube root of both sides.
x + 4 = cubrt(14)
x + 4 = 2.4101 Subtract 4
x = 2.4101 - 4
x = -1.5899
Answer:
3.5 K
Explanation:
When a sample of a substance releases heat energy, its temperature decreases according to the equation:
where
Q is the heat energy released
m is the mass of the substance
C is the specific heat capacity
is the initial temperature
is the final temperature
For the block of brass in this problem, we have:
m = 0.1 kg is the mass
Q = -56.4 J is the heat energy released (negative since it is released)
C = 380 J/kg K is the specific heat capacity of brass
is the initial temperature
Solving for , we find the final temperature:
