What?????????? what book????
Answer:
D) The term with a coeffiecient is 20w
Explanation:
5000 is not a variable
A constant is a number that is not changed by the variable.
w is a variable, not a coefficient
They are inverse of logarithmic equations. The value of b to the nearest tenth is 0.1
<h3>Exponential equations</h3>
They are inverse of logarithmic equations. Given the exponential function that modelled the penicillin concentration, in micrograms per milliliter as shown:

If the value of P(t) is 10, hence;

Take the ln of both sides
ln0.05 = 6/5 lnb
-2.995 = 1.2 ln b
lnb = -2.495
b = e^-2.495
b = 0.08
Hence the value of b to the nearest tenth is 0.1
