-13m = -377
m= -377/-13
m=29
the negatives cancel out. so just do 377/13 which equals 29
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
The stock worth now, to the nearest cent is $90.75.
<h3>How to find the current worth of stock?</h3>
The current worth of stock = initial price of stock+increase in the price of stocks
If you bought stock last year for a price of $103, and it has risen 13.5% since then,
Let X be the worth of stock;
103 × 100 = (13.5% + 100%) × X
10300 = 113.5X
X = 10300/113.5
X = 90.74889868
X = $90.75
Hence, The stock worth now, to the nearest cent is $90.75.

I have no clue what the answer is
21000
1000ml = 1 L
so
21 × 1000 = 21 000 milliliters
