Answer:
Step-by-step explanation:
The relationship between A, the area of the glacier in square kilometers, and t, the number of years the glacier has been melting, is modeled by the equation.:
We want to determine the value of t for which the area, A(t)=15 square kilometers.
Therefore, the time for which the area will be 15 sqyare kilometers is:
-20 ln(1/3) years.
The second table could represent relationship B.
Step-by-step explanation:
Step 1:
The tables give a relationship between the growth of a plant and the number of weeks it took.
To determine the rate of each table, we determine the growth of the plant in a single week.
The growth rate in a week = .
Step 2:
For the given graph, the points are (4, 3) and (8, 6).
The growth rate in a week =
So the growth rate for relationship A is 0.75.
Step 3:
Now we calculate the growth rates of the given tables.
Table 1's growth rate in a week =
Table 2's growth rate in a week =
Table 3's growth rate in a week =
Table 4's growth rate in a week =
Since relationship B has a greater rate than A, Table 2 is relationship B.
