Answer:

E_{T} = 36.84 J        

Step-by-step explanation:

La energía mecánica total está dada por:

E_{T} = E_{c} + E_{p}

E_{T} = \frac{1}{2}mv^{2} + mgh

En donde:

m: es la masa = 150 g

v: es la velocidad = 0.8 m/s

h: es la altura = 25 m

g: es la gravedad = 9.81 m/s²

E_{T} = \frac{1}{2}mv^{2} + mgh = \frac{1}{2}0.15 kg*(0.8 m/s)^{2} + 0.15 kg*9.81 m/s^{2}*25 m = 36.84 J

Por lo tanto, la energía mecánica total es 36.84 J.

Espero que te sea de utilidad!

P^2 - 4p - 32 / p + 4, simplify the rational expression. state any restrictions
dusya [7]

Answer:

The correct answer is: p - 8 ∧ restriction p ≠ -4

Step-by-step explanation:

(p² - 4 p - 32) / ( p + 4)

The existence of this rational algebraic expression is possible only if it is:

p + 4 ≠ 0  => Restriction is p ≠ -4

(p² - 4 p - 32) / ( p + 4) = (p² - 8 p + 4 p - 32) / (p + 4) =

= (p (p -8) + 4 (p -8)) / (p + 4)= (p - 8) (p + 4) / ( p +4) = p - 8

God with you!!!

Answer: D (bottom option)

Not Congruent

Step-by-step explanation:

Assuming the trapezoids are to scale, they are not the same shape. This means that they could not be congruent even if they were centered on top of each other.
