This is an exponential equation that can be represented by the following:
f(x) = a(b)^x
In this case...
25143 = a(0.66)^3
25143 is the population after 3 hours.
3 is the amount of time in hours.
0.66 represents the percent of the population remaining after each hour (66% as there is a 34% decline each hour).
We must solve for a, which is the initial population.
First, simplify (0.66)^3 to 0.2874.
25143 = 0.2874a
Now divide both sides by 0.2874 to isolate a.
a = 87455
There were initially 87,455 people within the city. I wouldn't want to be in that place!
Answer:
The answer would be C
Step-by-step explanation:
The only logical reason would be positive because the parabola is opening up. The average rte of change is opening 0.5 per square
X^2 = 1994
x= + - sqrt (1994)
Unfortunately, there is no integer that can suit x.
<span>two pairs of decimals that add up to 14.1 would be 8.4 and 5.7</span>
The value of x is -3, or x= -3
