You can put each into standard form to see whether they have the right value.
5.5·10⁴ = 55,000 ≠ 0.00055
We were told that the distance
is directly proportional to the time
.
We write this mathematically as,

We can now introduce our constant of variation and write the equation for the direct equation as;

where
is the constant of variation or constant of proportionality.
We substitute
and
, in to the equation of variation to obtain the constant of proportionality.
That is;

This implies that,

This simplifies to give us,

Now our equation of proportion becomes,

When T=20


Writing this as a mixed number we obtain,

This can also be rewritten as
correct to one decimal places.
Therefore the care covers
miles in
minutes.
Answer:
12x + 6
Step-by-step explanation:
3(4x + 2)
you distribute the 3 to 4x and 2
12x + 6
hope this helps
Explanation:
The average value of the velocity function is the height of the rectangle that has the same area as the velocity curve. That height is still measured in m/s.
If you want to find distance traveled (in m), then you must multiply the height in m/s by the width in s.
