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:

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

Entonces obtenemos

E identificamos que el radio del tanque es 4 metros y por tanto su perímetro es 8 metros
Answer:
What triangle?
Step-by-step explanation:
Answer: 6/625 gallons of water wa splashed out of the pool
Step-by-step explanation:
Total number of gallons of water in the pool was 10 1/2. Converting to improper fraction, it becomes
21/2 gallons.
Jake and his friend splashed g gallons of water out of the pool. There are 7 7/8 gallons still left in the pool. Converting 7 7/8 to improper fraction, it becomes
63/8 gallons
This means that
g + 63/8 = 21/2
g = 21/2 - 63/8 = (84 - 63)/8
g = 21/8 = 2.625 gallons
Answer: (0,1)
Step-by-step explanation:
If
and
are two point son a coordinate plane and (x,y) dividing it in a ratio of m: n.
Then , the coordinates of (x,y) is given by :-


Given : On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, - 3) and point B is at (- 4, 9).
Then , the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 :


Hence, the x- and y- coordinates of point E = (0,1)
