Answer:
11
Step-by-step explanation:
<span>A 0.176 times 10 to the power of 18 km =
</span><span><span>A 176.0 times 10^15 km
</span>B 22.13 times 10 to the
power of 16 km =
2.213 x 10^15 km
C 31.42 times 10 to the power of 14 km =
3.142 x 10^15 km
D 125.5
times 10 to the power of 15 km
</span>
The recalculated list is now:
<span>A 176.0 times 10^15 km
</span>
<span>B 2.213 x 10^15 km
</span><span>C 3.142 x 10^15 km
</span>
<span>D 125.5 x 10^15 km
</span>
Just by looking, we can see the 2 stars closest to each other are
<span>C 3.142 x 10^15 km and
</span><span>B 2.213 x 10^15 km
The distance between them = </span>3.142 x 10^15 km -<span>2.213 x 10^15 km
.929 x 10^15 km =
9.29 x 10^14 km

Answer:
So it would takes approximately 6.9 hours to reach 32 F.
Step-by-step explanation:
For this case we have the following differential equationÑ
We can reorder the expression like this:
We can use the substitution and so then we have:
IF we integrate both sides we got:
If we apply exponential in both sides we got:
And if we replace w = u-T we got:
We can also express the solution in the following terms:
For this case we know that since w ehave a cooloing, , we have this model:
And if we want that the temperature would be 32F we can solve for t like this:
If we apply natural logs on both sides we got:
So it would takes approximately 6.9 hours to reach 32 F.
