Answer:
k = 0.02278
Step-by-step explanation:
Given that:
The population P = 1674.7e^kt
where;
t represents the year,
if year 2000 represents t = 0
Then, the year 2007 represents = 7; &
year 2006 represents = 6
In 2006, population recorded in the city was about 1,920 thousand
Therefore;

Taking the logarithm of both sides, we get:

7.560080465= 7.423389324 + 6k
7.560080465 - 7.423389324 = 6k
0.136691141 = 6k
k = 0.136691141/6
k ≅ 0.02278
Answer:
false it changes the length but not size
Answer: 51
Step-by-step explanation:
From the question, we are informed that there are 2601 students in a school and that the teacher want them to stand in rows and columns.
Since the number of the row and column are equal, thus will go thus:
Let the number of row and column be represented by y. Therefore,
y × y = 2601
y² = 2601
y = ✓2601
y = 51
Therefore the rows and columns must be 51 each.
