If a bacteria population starts with 80 bacteria and doubles every four hours, then the number of bacteria after t hours is n = f(t) = 80 · 2t/4. (a) Find the inverse of this function.

Step-by-step explanation:

given that a bacteria population starts with 80 bacteria and doubles every four hours,

The function representing the number of bacteria after t hours

=

We are to find the inverse of the function

i.e. we must make t = g(n) where g is a function of n.

Take log on both sides.

this is the inverse function.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

b). 4320 have a nice day
