Answer:

c.(0, -√5) and (0, √5)

Step-by-step explanation:

The equation represents an ellipse centered on origin (0,0). First, the formula is rearranged to its cannonical form:

\frac{x^{2}}{4} + \frac{y^{2}}{9} = 1

The foci are located in the lines of the semimajor axes, so, the distance between the center and any of the foci is:

c = \sqrt{9 - 4}

c = \sqrt{5}

The foci are located at (0, -\sqrt{5}) and (0,\sqrt{5}). Hence, the answer is C.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
zalisa [80]

Answer: 272

Step-by-step explanation:

Let a1=11

a2=20

a3=29

Formula for sequence=

an=a1+(n-1)d

an = nth term

a1= first term

n= nth position

d= common difference

We are looking for the 30th term,so our n=30

d= a2-a1

d= 20-11

d= 9

Using the formula

an= a1+(n-1)d

a30= 11+(30-1)9

a30= 11+(29)9

a30= 11+(29×9)

a30= 11+261

a30= 272

Therefore, the 30th term is 272
