Y = 5x - 13<br><br> 4x + 3y = 18

hram777 [196]

<span>replace Y = 5x - 13
into
4x + 3y = 18

</span>

4x + 3 (5x - 13) = 18
4x + 15 - 39 = 18
4x -24 = 18
4x = 18 +24
4x = 42
x = 42/4
x = 10.5

Y = 5(10.5) - 13
= 52.5 - 13
= 39.5

answer: x = 10.5 and y = 39.5

Desde la parte más alta de un edificio a 25 m una persona lanza hacia la base un objeto de 150 g con una velocidad de 0.8 m por

ANTONII [103]

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.
