8 miles is approximately equal to 6 km. How many km are equal to 28 miles? How many miles are equal to 42 km?

1 answer:

3 0

1 mile = about 1 1/3 km because 8/6 = 1 1/3
so 28 times 1 1/3 = 37 1/3 (first answer)

42 / 6 = 7
7 miles are in 42 km (2nd answer)

For the following system, determine if a steady state exists and give the steady state value. The population of a colony of squi

Anettt [7]

Answer:

Option A)

$\displaystyle\lim_{t\to\infty}~p(t) = k$

Step-by-step explanation:

We are given the following on the question:

$p(t) =\displaystyle\frac{4000}{4+e^{-0.02t}}$

where p(t) is the population of a colony.

For steady state solution we evaluate:

$\displaystyle\lim_{t\to\infty}~p(t)\\\\= \lim_{x\to\infty} \frac{4000}{4+e^{-0.02t}}\\\\=\frac{4000}{4+e^{-\infty}}\\\\=\frac{4000}{4}\\\\= 1000$

Thus, the steady state solution is a constant, k = 1000.

Thus, the correct answer is

Option A)

$\displaystyle\lim_{t\to\infty}~p(t) = k$

Suponha que uma variável assume os valores: 11 – 8 – 7 – a – 16 – 10 Determine a de modo que a média aritmética seja igual 11.

Elenna [48]

Answer:

a = 14

Step-by-step explanation:

The mean is the sum of the values divided by the number of values.

$\begin{array}{rcl}\text{Mean}&= &\dfrac{11 + 8 + 7 + a + 16 + 10}{6}\\\\\dfrac{52 + a}{6}& = & 11\\52 + a & = & 66\\a & = & 66 - 52\\& = & \mathbf{14}\\\end{array}$

Find the x-intercepts, use the zero product property, r(r+7)=0

UkoKoshka [18]

9514 1404 393

Answer:

r = 0

r = -7

Step-by-step explanation:

There is no x in the equation, hence there are no x-intercepts.

If we assume you want the values of r that satisfy the equation, the zero product property tells you they will be the values that make the factors zero.

The factors are r and (r+7).

The factor r is zero when ...

r = 0

The factor (r+7) is zero when ...

r +7 = 0 ⇒ r = -7

The "x-intercepts" are r=0 and r=-7.
