The graph is still a straight line, it still cuts the y-axis at the point y=4 ,
and it still slants up from left to right.
But it becomes a lot less steep. The original line only had to go <em>4 inches</em>
to the right in order to rise 1 foot. The new line has to go <em>3-feet</em> to the right
in order to rise 1 foot.
Given:
The equation is:
To find:
The solution for the given equation.
Solution:
We have,
It can be written as:
Taking square root on both sides, we get
[Radius cannot be negative]
Therefore, the value of r is about 6.36 cm.

by proportion
Answer:
B) y = 6,071,675,206(1.012)^x
Step-by-step explanation:
It appears that this question asks for an exponential model that represents the population growth. I believe you could view the equation in the form y = (initial population)(rate)^x
Since the initial population is 6,071,675,206, you could substitute that in to get y = 6,071,675,206(rate)^x
Since your rate is increasing by 1.2% (0.012 in decimal form), just convert that to decimal form (knowing that 100% = 1.0, add 0.012 to get 1.012). Substitute that in to get y = 6,071,675,206(1.012)^x
Hope that helps. Feel free to let me know if it made sense.
