Answer:

The answer to your question is   \frac{x^{2} }{2} + \frac{y^{2} }{16} = 1

Step-by-step explanation:

Data

F ( 0, ± √14)

C (±√2, 0)

Process

1.- Calculate c

c is the distance from the center to the foci

c = √14

2.- Calculate b

b is the distance from the center to the co-vertices

b = √2

3.- Calculate a using the Pythagorean theorem

     a² = b² + c²

     a² = (√2)² + (√14)²

     a² = 2 + 14

     a² = 16

     a = 4

4.- We can conclude that it is a vertical ellipse because the foci are in the y- axis and the co-vertices are in the x-axis.

          (x - h)²/b² + (y - k)²/a² = 1

-Substitution

          (x - 0)²/(√2)² + (y - 0)²/4² = 1

- Simplification

          x²/2 + y²/16 = 1

or    \frac{x^{2} }{2} + \frac{y^{2} }{16} = 1

Lauren says that -3.5 is greater than -3 1/3. Do you agree? Explain.
kirza4 [7]

Answer:

-3\frac{1}{2}

Step-by-step explanation:

-3.5 means -(3 + \frac{1}{2})

In other words, -3.5 = -3\frac{1}{2}

When we draw two numbers -3\frac{1}{3} and -3\frac{1}{2} on a number line, -3\frac{1}{2} comes first from left to right.

We know that all the numbers on a number line from left to right are in increasing order.

Therefore, -3\frac{1}{2} is smaller than -3\frac{1}{3}.

-3\frac{1}{2}

Lauren is not correct.

Can someone help 12 points on the line
ANTONII [103]

Answer:

x=6

Step-by-step explanation:

We can write this as a ratio

x        9

---- = --------

10       15

Using cross products

15x = 10*9

15x = 90

Divide by 15

15x/15 = 90/15

x =6

Identify the like terms in the list.
MrRa [10]

Answer:

17x and 3x

Step-by-step explanation:

like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.
