Your exponential growth formula, P(t) = A e^(kt), contains two unknown constants, A and k. Once you find them, you can find the population for any t. (I assume, t is measured in years.) From your "story", you have:
<span>72 million = P(1992) = A e^(1992 k) </span>
<span>76 million = P(1998) = A e^(1998 k) </span>
<span>From these two equations, you can find the two unknowns A and k (do it yourself). Once you do, your answer is </span>
<span>P(2012) = A e^(2012 k)</span>
Answer:
C
Step-by-step explanation:
Try each one using the formula for the volume of a cylinder, pi * r^2 * h:
A. 3.14 * 12^2 * 5 = about 2261 which does not equal 565
B. 3.14 * 10^2 * 4 = about 1256 which does not equal 565
C. 3.14 * 6^2 * 5 = about 565 which is correct!
D. 3.14 * 6^2 * 10 = about 1130 which does not equal 565
Therefore C is the right answer.
Answer:
15 pints of paint 6 red 9 yellow
Step-by-step explanation:
3x3=9 so 9 yellow pints
and 2x3=6 so 6 red pints
6+9=15 so 15 pints of paint in total
Answer:
75%
Step-by-step explanation:
70-40 = 30
30/40 = 0.75
0.75 = 75%
