El agua sale por un tubo horizontal con un gasto de 2.45 lt/s. En un punto en que el tubo tiene una sección de 7 cm² la presión absoluta es de 0.9 kg/cm² . ¿Cuál debe ser la sección transversal de un estrechamiento del tubo para que la presión en él quede reducida 0.8 kg/cm²?

step-by-step explanation:

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
