18=2(5)+b
b=8 y intercept is 8
0=2(x)+8
-8=2x
x=-4
X intercept is -4
<span>A and C represent the same level of precision because they have the same number of places after the decimal point.</span>
Answer:
In 2012 , the population will be 15 million
Step-by-step explanation:
We start by setting up an exponential equation that defines the increase
P(t) = I(1 + r)^t
P(t) represents the present population = 15 million
I is the population in 2007 which is 13.8 million
r is 1.6% = 0.016
t is what we want to calculate
15 million = 13.8 million (1 + 0.016)^t
15/13.8 = (1.016)^t
1.09 = (1.016)^t
ln 1.09 = t ln 1.016
t = ln 1.09/ln 1.016
t = 5.429 which is approximately 5
So in 2007 + 5 = 2012, the population will be 15 million
1) I use an interest program on my calculator. You could also use the equation listed in the math textbook. Principle=2500 Rate=0.025 Years=3 No.compounds/yr=4 Answer is $2,694.08
