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:
D
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The product of the external part and the whole secant is equal to the square of the tangent, that is
8(8 - 6 + 2x) = 12²
8(2 + 2x) = 144 ( divide both sides by 8 )
2 + 2x = 18 ( subtract 2 from both sides )
2x = 16 ( divide both sides by 2 )
x = 8
Then
GH = - 6 + 2x = - 6 + 2(8) = - 6 + 16 = 10 → D
12 yd
You can use what you are provided with the 7 day and 5 yd which equal the side that is missing
7+5 =12
Dependent variable is dependent on the independent variable
m, because the amount of tread lost depends on how many miles you traveled
it's not, the amount of miles depends on how much tread you lost
m is indepdent
