Write the equation of the ellipse using the given information:
horsena [70]

We know, equation of ellipse is given by :

\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1

Here,

(h,k) is centre of the ellipse = (0,0).

a = major axis = 8.

b = minor axis = 4.

Putting all given value in above equation, we get :

\dfrac{(x-0)^2}{8^2}+\dfrac{(y-0)^2}{4^2}=1\\\\\dfrac{x^2}{8^2}+\dfrac{y^2}{4^2}=1\\\\\dfrac{x^2}{64}+\dfrac{y^2}{16}=1

Hence, this is the required solution.

Nostrana [21]

Answer:

  • D. 1/2x - 3

Step-by-step explanation:

  • (3/4x + 2) - (1/4x + 5) =
  • 3/4x - 1/4x + 2 - 5 =
  • 2/4x - 3 =
  • 1/2x - 3

Choose Yes or No to tell whether the expressions are equivalent. 1. 4(5c + 3) and 9c + 7 yes or no 2. 10f – 10 and 2(8f – 5) yes
Juli2301 [7.4K]

Answer:

1) No

2) No

3)Yes

4)No

Step-by-step explanation:

Distributive property: a(b + c) =a*b + a*c

1) 4(5c + 3) = (4*5c) + 4*3

                  = 20c + 12

NO

2) 2(8f - 5) = (2*8f) - (2*5)

                 = 16f - 10

NO

3) 3(4g + 7) = (3*4g) + (3*7)

                  = 12g + 21

YES

4) 6(4j - 6) =(6 * 4j) - (6*6)

                = 24j - 36

NO

What is the volume of this equation?
Pachacha [2.7K]

Answer:

Volume ≈ 33.33 cubic feet

Step-by-step explanation:

The question is:

<em>Find the volume of a right square pyramid with base square edges measuring 5 feet each and a height of the pyramid be 4 feet.</em>

<em />

So, the base is a square with side length 5 feet.

And the height of the pyramid is 4 feet.

The volume of a pyramid is given by the formula:

V=\frac{a^2 h}{3}

Where

a is the square base side length (given as 5)

h is the height of the pyramid (given as 4)

Now we substitute and find the value:

V=\frac{a^2 h}{3}\\V=\frac{(5)^2 (4)}{3}\\V=33.33

The volume is around 33.33 cubic feet
