Answer:
The explicit formula for f(n) is:

Step-by-step explanation:
The explicit formula is described by the following geometrical progression:

F(x)·g(x) = (3x +4)·(5 -x) = -3x^2 +11x +20
(f·g)(x) = -3x^2 +11x +20
Answer:
E = 216 joules
Step-by-step explanation:
The given equation is
E =
............(i)
Here
m = 3 kg
v = 12 m/s
Putting the given values in equation (i)
E = 
E = 
E = 
E = 216 kg m² /s²
or
E = 216 joules
