Solve for x.....................
polet [3.4K]

Answer:

B  x=3

Step-by-step explanation:

12x = 2x^2 +18

Divide by 2

12x/2 = 2x^2/2 +18/2

6x = x^2 +9

Subtract 6x from each side

6x-6x = x^2 -6x+9

0= x^2 -6x+9

Factor

What 2 numbers multiply to 9 and adds to -6

-3*-3 = 0

-3+-3 =-6

Fed [463]

Answer:

\large \boxed{\text{0.0462 min}^{-1}}

Step-by-step explanation:

One formula for the reproduction of bacteria is

\dfrac{N}{N_{0}} = e^{kt}

Data:

N = 2

N₀ = 1

  t = 15 min

Calculation:

\begin{array}{rcl}\dfrac{N}{N_{0}}& =& e^{kt}\\\\\dfrac{2}{1}& = & e^{k\times15 \text{ min}}\\\\2 & = & e^{15k \text{ min}}\\\ln 2 & = & 15k \text{ min}\\k & = & \dfrac{\ln2 }{\text{15 min}}\\\\& = & \textbf{0.0462 min}^{\mathbf{-1}}\\\\\end{array}\\\text{The value of the constant k is $\large \boxed{\textbf{0.0462 min }^{\mathbf{-1}}}$}
