During swim practice, an Olympic swimmer is required to complete three swimming intervals, in this order: warm-up freestyle, spr

int 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.

Answer:

I'm not sure if the warm up speed is less than the cool down speed.  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.  Also let me know if you can't read any of the labels

The figures are similar. find x. the ratio of the perimeters is 5:7​
anastassius [24]

Answer:

x = 16.8

Step-by-step explanation:

The ratio of corresponding sides is equivalent to the ratio of the perimeters.

Then using proportion

\frac{12}{x} = \frac{5}{7} ( cross- multiply )

5x = 84 ( divide both sides by 5 )

x = 16.8

A radio telescope has a parabolic surface. If it is 1m deep and 16m wide how far is the focus from the vertex?
Mrac [35]
Basing on the description, a parabola opening up with vertex at origin, the formula with vertex at origin is used, x^2 = 4py. p is the focus and so with the dimensions given, we obtain a 0.25 and that is the distance of the focus to the vertex.

5x+4.27xy+20y+36y-19x+9.11
mote1985 [20]
So what I did was the terms that were alike like this: (5x -19x)+(20y+36y)+4.27xy+9.11. Then I simplified and got -14x+56y+4.27xy+9.11. The terms 4.27xy and 9.11 were not in ()'s because they were the only ones with an alike term. Hope that helps and also try to doing the steps and see what you get. If you get it wrong look to see where you messed up and try again! If I am wrong please notify me, I would appreciate it!
