When a weed solution is added to a lawn, the number of weeds can be represented by the function W(d)=1500(.75)^d where d is the number of days since application. By what percent does the population of weeds decrease each day

Number of weeds is represented by the function,

-------(1)

Here, Number of days since application

Function representing the exponential decay is,

--------(2)

Initial value

Percentage decay

duration

By comparing both the functions (1) and (2),

0.25 ≈

Or 25%

Therefore, population of weeds will decrease 25% each day.

Learn more about exponential decay,

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
