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)

I’m confused on this one
erastovalidia [21]

In the chart of the triangle it shows that the variable b is the base. It also give us the equation for area 1/2bh (half of base * height)

Now we just plug in the values we are given

1/2bh

1/2(10*13)

1/2(130)

65

The area of the triangle is 65 ft

Molli purchased 8 apples for $2.96 while looking at her reciept molli divided $2.96 by 8. Why might molli perform this calculati
Basile [38]

B

Let’s put this into a simple equation

8 apples = 2.96

We can substitute apples for x

8x=2.96

She divided by 8

X= 2.96/8

Remember x represents apples so only 1 x represents 1 apple

So that means the answer is B.

Hope that helped!

Is 15b+4=25.6 equivalent to 0.6+15b+4=25.6
pychu [463]
No because
15b + 4 = 25.6
15b = 21.6
b = 1.44

0.6+15b+4 = 25.6
4.6 + 15b = 25.6
15b = 21
b = 1.4

The answers are not the same therefore they are not equivalent.
