Ответ:
83.56/p
Step-by-step explanation:
Let the weight of the players = p
Let the weight of the reserve players = r
Since there 9 players, there weight = 9p
And since there 3 reserve players, there weight = 3r
(9p + 3r) / 12 = 188
9p + 3r = 12 * 188
9p + 3r = 2256
Solve for r
r = 2256 / 27p
r = 83.56/p
Ответ:
f(x)=1 for x <0. The domain is x<0 or (-oo, 0)
the range is {1}
f(x)=(x-2)^2-3
the domain is (0, 4)
can substitute in values or graph.
The range is [-3, 1)
