Answer:
B, C
Step-by-step explanation:
Consider all options:
A. The graph of the function is vertically shrunk by a factor
the graph of the function
so the domain and the range of both functions are the same. This option is false.
B. The graph of the function is vertically shrunk by a factor
the graph of the function
so the domain and the range of both functions are the same. This option is true.
C. The graph of the function is translated 2 units to the right and vertically shrunk by a factor
the graph of the function
so their graphs are similar except the first graph is shifted right and shrunk vertically by a factor of
. This option is true.
D. The function has the domain and the range all non-negative real values. The function
has the domain and the range all real values. So this option is false.
Answer:
The differential equation is
Step-by-step explanation:
Differential equation for the rate of change in radiation level:
Radiation level is R.
Rate of change indicates that the radiation level R varies in function of time t, which mathematically means that we have:
After the reactor is shut down, the radiation from the nitrogen-17 decreases in such a way that the rate of change in the radiation level is directly proportional to the radiation level.
Rate of change is k. Decreases means that k is negative. Proportional to the radiation level of R means that -k multiplies R. So the differential equation is:
