Answer:
So it will take 15 year from 1998 to reach population 229 thousands.
i.e. In 2013 population will be 229 thousand.
Step-by-step explanation:
Given:
Formula model population for city A=146e0.03t
To Find:
Years required to reach population 229 thousands after 1998
Solution:
Using the model ,
A=146e0.03t
here A=229
So equation becomes,
229=146e0.03t
(229/146)=e0.03t
Using log function with base 10 on both sides we get ,
Log(229/146)=log(e^0.03t)
log(1.56489)=0.03tlog(e) .................(using log property log(a^n)=nloga)
0.19548=0.03*t*0.43429
0.19548/0.013028=t
t=(0.19548/0.013028)
t=15.01
t=15 years
So it will take 15 year from 1998 to reach population 229 thousands.
Answer:
10x^2+x-2
Step-by-step explanation:
(2x+1)(5x-2)
10x^2+5x-4x-2
10x^2+x-2
Answer:
Given diameter: r = d / 2 , Given area: r = √[A / (4 * π)] , Given volume: r = ³√[3 * V / (4 * π)] , Given surface to volume ratio: r = 3 / (A/V) .
Step-by-step explanation:
So, do that!
There are multiple answers, you would need to know some of the other variables. Just do this. 70 - ( y * b) = r
