A culture of bacteria has an initial population of 72000 bacteria and doubles every 10 hours. Using the formula P = Po · 21, where Pt is the population after t hours, Po
is the initial population, t is the time in hours and d hs the doubling time, what is the
population of bacteria in the culture after 17 hours, to the nearest whole number?

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

c) yes, because of asa or aas

what? that isnt a question

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
