Answer:
Initial value = 4
Growth factor = 1.6
Step-by-step explanation:
Function representing the exponential growth is given by,
f(x) = Initial value(1 + growth rate)ˣ
Here x = time or duration for growth
(1 + growth rate) = Growth factor
Given function is,
f(x) = 4(1.6)ˣ
By comparing both the functions,
Initial value = 4
Growth factor = 1.6
It doubles every 4 hours, so after 24 hours there will be 6 doublings.
2^6 = 64
So, the population will be (3,000,000 * 64) or 192,000,000 in 24 hours.
The answer is B.
5x^4
Step-by-step explanation:
simply we take 5x^4 bec. it can be divided by 40 and 135
Answer:
There will be 
billion messages sent or received in November.
Step-by-step explanation:
Given.
Number of text messages sent or received 
billion.
Increment on the very next month 
Lets find what is 
⇒
⇒
So we will add this value to our previous months data.
Now
Number of text messages sent in the month of November 
billion.
Rounding to the nearest tenth the answer will be billion.
So billion text messages were sent or received in November.
