The graph shown below shows once complete normal breathing cycle. The cycle consists of inhailing and exhailing. It takes place every 5 seconds. Velocity of air flow is positive when we inhale and negative when we exhale. It is measure in liters per second. If y represents velocity of air flow after x seconds, find a function of the form y=A sinBx that models air flow in a normal breathing cycle.

step-by-step explanation:

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

sina-sinb

cosb+cosa

tana-tanb

cos0+cos x pi/3

20tan

step-by-step explanation:

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
