Answer:
138 fluiere, 158 ocarine, 184 viori
Step-by-step explanation:
given:
(1) fluiere + ocarine +viori = 480
(2) fluiere + ocarine =296
(3) ocarine + viori =342
din ecuatia (3) avem: viori= 342-ocarine
din ecuatia(2) avem : fluiere= 296-ocarine
in ecuatia (1) inlocuieste ce ai gasit ca sa fie o ecuatie doar cu necunoscuta ocarine: fluiere + ocarine +viori = 480
296-ocarine +ocarine+ 342-ocarine =480
296+342-480 = ocarine =158
viori = 342-158 = 184
fluiere = 296-158 = 138
Answer:
Conversely, given a pair of parametric equations with parameter t, the set of points (f(t), g(t)) form a curve in the plane.
As an example, the graph of any function can be parameterized. For, if y = f(x) then let t = x so that
x = t, y = f(t).
is a pair of parametric equations with parameter t whose graph is identical to that of the function. The domain of the parametric equations is the same as the domain of f.
Example The parametric equations
x = t, y = t2
