Who wants me to asnwer all their questions?
i will answer all ur questions that u asked if u answer this:

during swim practice, an olympic swimmer is required to complete three swimming intervals, in this order: warm-up freestyle, sprint freestyle, and cool-down breast stroke. after he completes each interval, he rests for three minutes.
sketch a graph that represents the swimmers’ interval times with respect to swimming speed. assign the x- and y-axes with appropriate labels. you may use description words instead of numbers to label the graph.

Search up heating curve chemistry: it should look somewhat like that lol :). But, the last interval should have a small slope, the middle interval a big slope, and the first interval: a medium slope.

Step-by-step explanation:

If it is different than how I did it you just need to swap their positions on the y axis, so the "lumps" or whatever you want to call the shapes will be in opposite positions.  The middle one will stay the same because it is the fastest and in between the two happening.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
