Se dau triunghiurile abc si def. stabiliti dacă cele doua triunghiuri sunt asemenea in următoarele situații:
a)ma=38 de grade; mb=65; me=65; mf=70
b)ma=45; mc=mf=54; md=81
c)mb=me=70m; a=40m; mf=60
d)mc=45; ma supra mb=5supra4; md=75me=60

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
