Tyona is performing a biology experiment
in which she is studying how the number of
bacteria in a dish changes over time. The
initial number of bacteria in the dish was
1150, and after several hours of monitoring,
Tyona was able to determine that the
number of bacteria was doubling at the end
of each hour,
Write a function, b(t), that Tyona can use to
determine the number of bacteria in the dish
after t hours,

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
