In this problem, volume is computed:
volume = ∫(flow rate)·dt
.. = ∫[0, t] (3/10)*sin(2πt/7)·dt
= (3 / 10)*(7 /(2 π))*(-cos (2 π t/7)+1)
= (-21 / (20 π))*(cos (2 π t /7) - 1)
Volume is equal to 21 sin^2 (pit/7) / 10pi is the inhaled air in the lungs at time t
Answer:The other endpoint is at (
−
4
,
3
)
Explanation:
The line segment passing through (
−
4
,
9
) and (
−
4
,
6
)
is a vertical line with the midpoint 3
units below the first point.
The other endpoint must be 3
further units below the midpoint
i.e. at (
−
4
,
(
6
−
3
)
Step-by-step explanation:
For 6: 12, 18, 24, 30, 36
For 9: 18, 27, 36, 45, 54
For 7: 14, 21, 28, 35, 42
