Answer:
Buenos días;
1) La ecuación de la velocidad en un movimiento uniformemente acelerado (M.U.A) es:
V=V₀+at.
V=30 m/s-2 m/s².t
Ahora elimina las unidades (m/s, m/s₂), y tendrás la ecuación de la velocidad en función del tiempo.
V(t)=30-2t.
Sol: la ecuación de la velocidad en función del tiempo es : V(t)=30-2t.
2) La ecuación de la posición en función del tiempo en un M.U.A es:
X=X₀+V₀.t+(1/2).a.t²
X=0+30 m/s.t+(1/2).(-2 m/s²).t²
Eliminas las unidades, y tendrás la ecuación de la posición en función del tiempo.
X(t)=30.t-t².
Sol: la ecuación de la posición en función del tiempo es: X(t):30t-t²
Un saludo.

Answer:
A & B are independent events. A & C, B & C are not independent events.
Step-by-step explanation:
Independent Events are the events, whose occurrences are completely unrelated to each other.
Event A 'Red dice getting 3' & Event B 'Green die getting 4' ; are unrelated to each other. The numbers on red dice & on green dice are not dependent on each other.
Event C 'Red & Green dice numbers showing sum = 7' is dependent on the numbers coming on red & green dice , i.e events A & events B respectively. So, event C is dependent on both events A & B.
Answer:
80 Cubic Units
Step-by-step explanation:
5 x 4 = 20
20 x 4 = 80
Hope it helps :)
That is known when there is no like terms to be added, and for the case of a fractional function: there is no more common factors between the numerator and the denominator.
Hope that help
Answer:
82
Step-by-step explanation:
The shape formed by the three lines is a triangle. That would mean all of the angles must add up to 180 degrees.
53+45=98
180-98=82
