Para el diseño de un tanque de tratamiento de agua se determina que su centro está ubicado en la posición (0;14) metros y está r
Andreas93 [3]

Answer:

Diámetro = 8 metros

Step-by-step explanation:

La ecuación de la circunferencia esta en la forma general y para identificar su centro y su radio debemos llevarla a la forma canónica completando cuadrados:

x^{2} +y^{2} -28y + 180= 0

Solo necesitamos completar cuadrados en la variable y, sumando a ambos lados de la ecuación 196, que resulta de dividir 28 entre 2 y elevarlo al cuadrado

x^{2} +y^{2} -28y + 196 = -180 +196

Entonces obtenemos

x^{2} + (y-16)^{2} = 16

E identificamos que el radio del tanque es 4 metros y por tanto su perímetro es 8 metros

Two students, Raymond and Shauna, are trying to get city council members to vote for a new park along the river. 2/6 of the 24 c
galina1969 [7]
Raymond and Shauna must convince at least 5 more city council member. Because if every 2/6 members agree with the idea, then there would be 8 people out 24 that already agree with the idea. So if you have already 8 members then to make 13, you just need 5 (8 + 5=13) more people to 13.

i walked 3y - 2c + 600 meters yesterday. today, i walked 10,000 meters. how many more miles did i walk today?
Leokris [45]
To find out how much more you walked today, you want to find the difference between the two days, which is 10,000-(<span>3y - 2c + 600) = 9400-3y+2c using the distributive property (the negative sign in front of the parenthesis is essentially a -1)</span>
