The initial population is P₀ = 650,000.
Growth rate, r = 5% per year, or r = 0.05.
Let t = years.
The proposed model is
or
Therefore
ln(P/650000) = 0.05t
When P = 1,000,000
0.05t = ln(1000000/650000) = 0.4308
t = 8.6157 years = 2 years (approx)
Answer: 2 years (approx)
Answer:
The final estimate of √388 is 20.
Step-by-step explanation:
The number provided is:
<em>x</em> = 1388
Estimate the square root of 1388 as follows:
15² = 225
16² = 256
17² = 289
18² = 324
19² = 361
20² = 400
So, we now know that the square root of 388 lies between 19 and 20.
Check for 19.5²:
19.5² = 380.25
Check for 19.6²:
19.6² = 384.16
Check for 19.7²:
19.7² = 388.09 ≈ 388
The square root of 388 is closer to 19.7 or is approximately 20.
Thus, the final estimate of √388 is 20.
