Find the standard form of the equation of the ellipse with the given characteristics and center at the origin.

Mathematics

Rufina [12.5K]3 years ago

Answer:

The equation of the ellipse is \frac{x^{2}}{9} + \frac{y^{2}}{5} = 1

Step-by-step explanation:

Let the equation of the ellipse is \frac{x^{2}}{a^{2}} +  \frac{y^{2}}{b^{2}} = 1 {As the center of the ellipse is at the origin}

Therefore, the vertices of the ellipse are (± a,0) and foci are (± ae,0)

Now, given that a = 3 and ae = 2

Now, eccentricity of a ellipse is given by b² = a² - a²e² = 3² - 2² = 5

Therefore, the equation of the ellipse is \frac{x^{2}}{9} + \frac{y^{2}}{5} = 1 (Answer)

Write an<br> explicit formula for An, the nth term of the sequence 7, -42, 252, ....
erik [133]

Answer:

A_n = 7(-6)^{n-1}

Step-by-step explanation:

<u>Key skills needed: Explicit formula, Geometric sequence</u>

1) This is a geometric sequence, meaning a constant (like 6 or 3.5) is being multiplied to every term. First we need to find the constant.

This can be done by doing -42 ÷ 7   or   252 ÷ -42

-42 ÷ 7 equals -6.

252 ÷ -42 also equals -6.

2) This means that constant is -6.

3) The general form for an explicit formula of a geometric sequence is:

a_n = a_1(r)^{n-1}

--> r means the constant (or common ratio) that is being multiplied.

--> a_1 means the first term

--> a_n means the "nth" numbered term (so a_3 is the 3rd term, a_{10} is the 10th term and so on).

--> n-1 is just the "n" in a_n minus 1.

4) We can use this formula to create an explicit formula for the geometric sequence in the problem.

--> r = -6 (Since we got -6 as the constant/common ratio).

--> a_1  = 7 (Since 7 is the 1st term)

This means that our formula would be --> A_n = 7(-6)^{n-1}

Solve -1 3/8 K equals 2/3
guajiro [1.7K]

Answer:

  K = -16/33

Step-by-step explanation:

For a problem like this, it is convenient to write the mixed number as an improper fraction:

  -11/8 K = 2/3

Now, multiply the equation by the reciprocal of the coefficient of K.

  K = (-8/11)(2/3)

  K = -16/33
