The length of model is ......15 inch
if the scale factor is 1/20
it means 1/20=15/h
h=12*15=300
Answer:
Y = .2x + 6.95
Step-by-step explanation:
x = minutes, which is being multiplied every 20 cents.
Then the 6.95 is added to number of dollars
Answer:
101.4 liters.
Step-by-step explanation:
First of all we will find mileage of car.
We can see that car travels at the rate of 7.12 miles per liter gas. Now let us find amount of gas needed to travel 722 miles at the same rate.
Therefore, it will take 101.4 liters of gas to travel 722 miles.
Looks like we're given
which in three dimensions could be expressed as
and this has curl
which confirms the two-dimensional curl is 0.
It also looks like the region is the disk . Green's theorem says the integral of along the boundary of is equal to the integral of the two-dimensional curl of over the interior of :
which we know to be 0, since the curl itself is 0. To verify this, we can parameterize the boundary of by
with . Then
