What you must do is evaluate the function for the given conditions and thus be able to find the constants A and k
25 = Ae ^ k (2005)
31 = Ae ^ k2010
We then have two equations with two unknowns.
Solving.
25/31 = e ^ k (2005-2010)
Ln (25/31) = k (2005-2010)
k = Ln (25/31) / (2005-2010) = 0.043
Substituting k in any of the equations:
25 = Ae ^ (0.043 * (2005))
Clearing A
A = 25 / (e ^ (0.043 * (2005))) = 9.02E-37
Then, by 2020
P = (9.02E-37) e ^ (0.043 * (2020)) = 48 million
answer
the population for 2020 will be 48 million
Answer:
6 12/15 = 102/15
10 5/10 = 105/10
Step-by-step explanation:
6 12/15 = 102/15
10 5/10 = 105/10
Option b. -2 is the output of the function
Answer:
D. 0.45
Step-by-step explanation:
Median is everything added up, then divide by the amount of numbers you have.
30+31+37+36+31+35+34=234
then divide by 7 and you get 33.42
30+31+37+36+31+35+34+37=271
then divide by 8 and you get 33.87
33.87 and 33.42 have a difference of 0.45
Slope is change in y / change in x
Using the two points given:
Slope = (5-4) /(2-4) = 1/-2 = -1/2
slope = -1/2
