To make a square for x²+bx=c, add( 
)²on both side
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.

Answer:
The constant force exerted on the ball by the wall is 119.68 N.
Step-by-step explanation:
Consider the provided information.
It is given that the mass of the ball is m = 2.2 kg
The initial velocity of the ball towards left is 7.4 m/s
So the momentum of the ball when it strikes is =
The final velocity of the ball is -6.2 m/s
So the momentum of the ball when it strikes back is =
Thus change in moment is:
The duration of force exerted on the ball t = 0.25 s
Therefore, the constant force exerted on the ball by the wall is:
Hence, the constant force exerted on the ball by the wall is 119.68 N.
Answer:
Media = 4.1
Mediana = 4
Moda = 4
Step-by-step explanation:
3 personas obtuvieron 5 puntos
5 personas obtuvieron 4 puntos
2 personas lograron 3 puntos
a. La media se da como:
Media = suma total de marcas / número de personas
Por lo tanto, la media será:
b. Para obtener la mediana, tenemos que organizar los términos en consecuencia y encontrar el número en el medio.
3, 3, 4, 4, 4, 4, 4, 5, 5, 5
Como no hay un número único en el medio, la mediana es:
(4 + 4) / 2 = 8/2 = 4
c. La moda es el número que aparece más, y eso es 4
