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:
a.) 4 half lives have passed
b) 9.388 minutes
Step-by-step explanation:
Formula for exponential growth / decay is given as:
Where is the final population
is the initial population
is the growth factor
is the time taken for the growth 'b'
is the amount of time
Here, we are given that:
= 6. 9 grams
= 110.4 grams
min
To find:
a.) Number of half lives taken for the decay.
b.) Total time in the decay.
Solution:
a.) Number of half lives taken for the decay is nothing but equal to .
Putting the values in the formula, we get:
Therefore, the answer is:
<em>4 half lives </em>have passed.
b.) Total time of decay. We have to find the value of here.
From answer of part a.):
