Last one:
f(x)= (1+r)^x, then find r=0.07-1=-0.93,
negative---> decay, and then 0.93==93%
f(x)= (1+r)^x, then find r=0.07-1=-0.93,
negative---> decay, and then 0.93==93%
Answer:
Exponential decay of 93%
Step-by-step explanation:
A function is shown below:
f(x) = (0.07)^x
Exponential formula is
[tex]f(x)= a(1+r)^t[/tex]
r is the rate of growth or decay
From the given f(x) , we have 1+r = 0.07
Subtract 1 from both sides
[tex]r= 0.07 -1[/tex]
[tex]r= -0.93[/tex]
To get % we multiply by 100
r= -93%
the value of 'r' is negative , so its exponential decay
Exponential decay of 93%
