What is the length of the major axis of the conic section shown below?

sveticcg [70]

$\dfrac{(x-2)^2}{49}+\dfrac{(y+5)^2}{36}=1$

The equation of a elipse:

$\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1$

The length of the major axis is equal 2a if a > b or 2b if b > a.

We have

$a^2=49\to a=\sqrt{49}=7\\\\b^2=36\to b=\sqrt{36}=6\\\\a > b$

therefore the length of the major axis is equal 2 · 7 = 14.

Use the domain and range of each of the following relations to determine which is a function.

Setler79 [48]

Answer:

A) Not a function

B) Function

C) Function

D) Not a function

Step-by-step explanation:

If the relation has two of the same x-values (that equal different y-values), it is not a function. In other words, if each input value leads to only one output value, classify the relation as a function.

{(-4,3), (-2,-1), (-4,8)} = Not a function

{-4, 3), (-2.-1), (-7, 8)} = Function

{-4,-2,-7, 7} = Function (I think?)

{-4,3). (-2, -1). (-2, -8), (-7,8)}= Not a function
