We assume the annual percentage increase is the same. We will work out the constant k using the formula
We have
P = 76
A = 72
t = 6 years (from 1992 to 1998)
Substitute into the formula
Take log both sides give
We can now work out the number of population by the end of 2012 using the formula
We have
A = 72 million
k = 0.009
t = 10 years (1992 to 2012)
≈79 million

<span>ralph = r
sara = s
ralph is TODAY, 3 times older, so if sara is "s" old, ralph is 3s
r = 3s
in 6 years, ralph will be 2 times as old as sara THEN,
in 6 years ralph will be TODAY's age plus 6, so r + 6
so if sara is "s" old, r+ 6 = 2s
r + 6 = 2s</span>
I got x = 96/18 i dont think the answer is there
You can rent a paddleboat at Lake Isabel. The cost is $15 for the first hour - then $9 for each hour after that. Use this information to complete the following: Write an equation in slope intercept form that represents the cost (y) of the rental based on the number of hours (x) you rent it. b) What is the y intercept of your equation? c) What does this mean in the context of the situation? d) What is the slope of your equation? e) What does this number mean in the context of the situation? f) Graph the line that is represented by your equation. Make sure to clearly label the axis. g) How much will it cost to rent the paddleboat for 4 hours? Show how you found your answer algebraically. Also show and explain where this information can be found on your graph.
