Answer 4

describe how to find the multiplier for an exponential growth rate of 15%

Answer 5

do you mean the growth constant?

Answer 6

15/100

Answer 7

0.15

Answer 8

my mistake

Answer 9

@chikitagee what's the whole problem? is the time given? we cant solve it without time

Answer 10

15/100 +1 = 1.15

Answer 11

it just says to describe how to find the multiplier for an exponential growth rate of 15% and describe how to find the multiplier for a rate of decay of 15%

Answer 12

for growth, 15/100+1 = 1.15
for decay, 1- 15/100 =0.85

Answer 13

oh wait i dont think time is needed. it's already implicity given

when time = 1 then the population would be x = x_0 + 0.15 x_0

where x_0 is the initial population

now use the formula
\[\ln (\frac{x_0}{x}) = kt\]
like i said x = x_0 + 0.15 x_0 and t = 1

\[\ln (\frac{x_0}{x_0 - 0.15 x_0}) = k\]
\[\ln (\frac{\cancel{x_0}}{\cancel{x_0}(1 - 0.15)}) = k\]
\[k = \ln (\frac{1}{1- 0.15})\]
does that help?
