Answer:
0.08 m/s²
Step-by-step explanation:
a = (v − v₀) / t
a = (0.4 m/s − 0 m/s) / 5 s
a = 0.08 m/s²
Answer:
5y - 2x = 0
Step-by-step explanation:
Equation of line is given by,
y - y1 = ( x - x1 ) ( y2 - y1)/ (x2 - x1 )
y - 0 = ( x - 0 ) ( 2 - 0 )/ ( 5 - 0 )
y = 2x /5
5y = 2x
5y - 2x = 0
This is the required equation.
THe LCD is x(x^2 - 4)
so multiplying through by this we get:-
2x(x + 2) + 7x = 5(x^2 - 4)
2x^2 + 4x + 7x = 5x^2 - 20
3x^2 - 11x - 20 = 0
(3x + 4)(x - 5 ) = 0
so x = 5 , -4/3
Its the second choice
