A bacteria culture has 2,000 bacteria. The number of bacteria increases by 5% each hour. How many bacteria are there after 12 ho
ivann1987 [24]
Suppose the number of bacteria are increasing exponentially, We can model the number of bacteria at a given time t, using the formula:
f(t)=ae(tk)
where, k=constant of proportionally and a=initial number;
thus;
f(t)=2000e(0.005t)
Therefore the population after 12 hours will be:
f(12)=2000e^(0.005*12)
f(12)=2,123.67=2,123 bacteria

vagabundo [1.1K]

Answer:

  $57.63

Step-by-step explanation:

For x > 3, the price in dollars Mr. Roshan will pay for x pounds of beef is ...

  cost = 4.99×3 +4.49(x -3) = 3(4.99 -4.49) +4.49x

  cost = 1.50 +4.49x

Then for x = 12.5 pounds, the cost is ...

  cost = 1.50 +4.49×12.5 = 1.50 +56.13

  cost = 57.63

Mr. Roshan will pay $57.63 for 12.5 pounds of beef.

Answer:

Resistivity

Step-by-step explanation:

Resistivity : It is a fundamental property of a material that measures how strongly a particular material opposes the flow of electric current. It is also known as specific resistance.

  • A low resistivity indicates a material that easily allows the flow of electric current.
  • Resistivity is commonly represented by the Greek letter ρ (rho) or abbreviated with a a capital letter K. The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).

Hence, the correct answer for the blank is Resistivity.
