Answer:

Again, A.

Step-by-step explanation:

Just graph the equation, but you can tell just by looking at it that (0,11) is the y-intercept meaning that it's one of the answer choices.

3) The International Space Station takes 644 minutes to orbit Earth 7 times. About how long does each orbit take? I got 92 am I

taurus [48]

Given:

The International Space Station takes 644 minutes to orbit Earth 7 times.

To find:

The time taken by each orbit.

Solution:

Total time = 644 minutes

Total number of orbits =7

Now,

$\text{Time taken be each orbit}=\dfrac{\text{Total time}}{\text{Number of orbits}}$

$\text{Time taken be each orbit}=\dfrac{644}{7}$

$\text{Time taken be each orbit}=92$

So, the required time is 92 minutes.

Therefore, you are correct and all options are incorrect.

Plutonium-240 decays according to the function L where o

PIT_PIT [208]

Answer:

$\boxed{\textbf{1700 yr}}$

Step-by-step explanation:

$-\dfrac{\text{d}L}{\text{d}t} = kL\\\\\dfrac{dL}{L}=-kdt\\\\\ln L = -kt + C\\\text{At t = 0, L = L$_{0}$, so C = $\ln L_{0}$}\\\ln L = -kt + \ln L_{0}\\\ln L_{0} - \ln L = kt\\\\\ln \dfrac{L_{0}}{L} =kt$

Data:

L₀ = 24 g

L = 20 g

k = 0.000 11 yr⁻¹

Calculation:

$\ln \dfrac{24}{20} =0.000 11t\\\\\ln 1.2 = 0.000 11t\\\\0.1823 = 0.000 11t\\\\t = \dfrac{0.1823}{0.000 11} = \textbf{1700 yr}\\\\\text{It will take } \boxed{\textbf{1700 yr}}\text{ for the polonium to decay to 20 g}$
