Answer:

The constant of proportionality k = 12

Hence, option A is true.

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get

y ∝ x

y = kx

Where 'k' is called the constant of proportionality.

In our case,

The given equation is

y = 12x

comparing with the equation y = kx, we can say

k = 12 which is the constant of proportionality.

Therefore, we conclude that:

The constant of proportionality k = 12

Hence, option A is true.

Answer:

$\frac{1}{4x}$

Step-by-step explanation:

The negative exponential can be represented with the help of fractions. By this way, we also make the negative exponential disappear. For example, we can write:

$a^{-1} = \frac{1}{a}$

The explanation is this:

Since $a^{0}=1, \frac{1}{a}=\frac{a^{0} }{a^{1} } = a^{0-1} =a^{-1}$

According to this definition, we can simplify our problem in the following way:

$(4x)^{-1} = \frac{1}{(4x)^{1} } = \frac{1}{4x}$

Answer:

$n(t)=n_0e^{(1-e^{-t }-t)}$

Step-by-step explanation:

If n(t) represents the population size at time t, where n is measured in individuals and t is measured in years.

$\frac{dn}{dt}=n(e^{-t }-1), n(0)=n_o$

$\frac{dn}{n}=(e^{-t }-1)dt$

Taking the integral of both sides

$\int\frac{dn}{n}=\int(e^{-t }-1)dt\\\int\frac{dn}{n}= \int e^{-t }dt-\int1dt$

ln |n| = $-e^{-t }-t+C$

Where C is integration constant

Taking the exponential of both sides

$n=e^{(-e^{-t }-t+C)}$

$n=e^{(-e^{-t }-t)}e^C\\n=Ke^{(-e^{-t }-t)}$ whee the exponential of a constant is a constant K.

When t=0, $n(0)=n_o$

$n_0=Ke^{-1$

Therefore:

$n=n_0e^{1}e^{(-e^{-t }-t)}$

$n(t)=n_0e^{(1-e^{-t }-t)}$
