\frac{x^{2} }{36} + \frac{ y^{2}}{16} = 1

This is because the standard form of an ellipse is 

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

where a is the vertex and b is the co-vertex. So when we stick their respective x and y values in and then square them, you're left with the answer above.

Answer:

\frac{x^{2} }{36}+\frac{y^{2} }{16}=1

Step-by-step explanation:

As we know standard equation of n ellipse is \frac{(x-0)^{2} }{(-6)^{2}}+\frac{(y-0)^{2} }{(4)^{2} }=1

In the given equation (h, k) is the center, a is the vertex and b is the co-vertex.

Here vertex is (-6, 0) and co-vertex is (0, 4)

Therefore, length of a = -6, b = 4 and origin is (0, 0)

Now the equation of the ellipse will be

\frac{(x-0)^{2} }{(-6)^{2}}+\frac{(y-0)^{2} }{(4)^{2} }=1

\frac{x^{2} }{6^{2}}+\frac{y^{2} }{4^{2} }=1

\frac{x^{2} }{36}+\frac{y^{2} }{16}=1

Therefore, the equation of the ellipse will be \frac{x^{2} }{36}+\frac{y^{2} }{16}=1

What is the ratio for sine
Sphinxa [80]

Answer:

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Step-by-step explanation:

There is a trigonometric acronym for this which is:

Soh Cah Toa

Soh means that sine is opposite over hypotenuse.

Cah means that cosine is adjacent over hypotenuse.

Toa means that tangent is opposite over adjacent.

Let me actually write these out as fractions:

sine is \frac{\text{opposite}}{\text{hypotenuse}}

cosine is \frac{\text{adjacent}}{\text{hypotenuse}}

tangent is \frac{\text{opposite}}{\text{adjacent}}

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Estimate plz:<br> 137,638+52,091<br> Explain plz how to do it
IceJOKER [234]
The best way to estimate it is to do "written addition" in your head, adding 1+8, then 9+3, all the way until you get to the front. the actual answer is 189,459, so your answer should be somewhere close to that.
