<span>We can safely assume that 1212 is a misprint and the number of seats in a row exceeds the number of rows by 12.
Let r = # of rows and s = # of seats in a row.
Then, the total # of seats is T = r x s = r x ( r + 12), since s is 12 more than the # of rows.
Then
r x (r + 12) = 1564
or
r**2 + 12*r - 1564 = 0, which is a quadratic equation.
The general solution of a quadratic equation is:
x = (-b +or- square-root( b**2 - 4ac))/2a
In our case, a = 1, b = +12 and c = -1564, so
x = (-12 +or- square-root( 12*12 - 4*1*(-1564) ) ) / 2*1
= (-12 +or- square-root( 144 + 6256 ) ) / 2
= (-12 +or- square-root( 6400 ) ) / 2
= (-12 +or- 80) / 2
= 34 or - 46
We ignore -46 since negative rows are not possible, and have:
rows = 34
and
seats per row = 34 + 12 = 46
as a check 34 x 46 = 1564 = total seats</span>
distance is speed multiply by time, from speed equals distance divided by time so we have 100 multiply by 6 which is 600km
Answer:
Step-by-step explanation:
Any alteration to the x value means that the function will move right. There are no exceptions to this that I can think of.
Distance = 13.243 * 22.07= 292.27miles
From the graph, we can actually see that as the altitude increase, the
value of the pressure decreases. Or if we say it the opposite way, as the
altitude decreases (approaches sea level), the pressure increases, therefore
the answer is:
As the altitude approaches sea level, the atmospheric
pressure increases.
