During the exponential phase, E. coli bacteria in a culture increase in number at a rate proportional to the current population.

NikAS [45]

Answer:

197.2 million

Step-by-step explanation:

The appropriate exponential equation for the population is ...

p(t) = 172.0e^(0.019t)

Then we can compute for t=7.2:

p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2

7.2 minutes from now, the population will be about 197.2 million.

___

For continuous growth (or continuous compounding), the exponential formula is ...

f(t) = (value at t=0)×e^(rt)

where r is the growth rate in one unit of time, and t is the number of time periods.

HELP

adelina 88 [10]

Answer:

$(x-6)^2=8$

Step-by-step explanation:

$x^2-12x+32=4$

$x^2-12x+32+4=4+4$

$x^2-12x+36=8$

$(x-6)^2=8$

Basically, you need to add a number to both sides so that you can reduce the left side to a square. In this case, you add 4.

Answer:

Cost of fish = Php. 60, amount of fish = x kg
Cost of chicken = Php. 120, amount of chicken = y kg
Budget = at most Php. 1200

a) Required inequality (not a system as only one condition is given):

60x + 120y ≤ 1200

Simplified:

x + 2y ≤ 20

The graph is attached

b) Verify ordered pair (10, 7):

10 + 2*7 ≤ 20
24 ≤ 20

False inequality, so this pair is out of solution set
