Remark
The general equation for an ellipse is
$\frac{x^2}{a^2}+ \frac{y^2}{b^2}=1$

At the center, the the point is 0,27

Solving for the
$\frac{0}{a^2} + \frac{27^2}{b^2} = 1$
or b^2= 27^2 * 1
Taking the square root of both sides
b = 27

Now we need to use one more piece of information
The second point is (24,9) what that means is at the point x = 24, y = 9

Solving for that
$\frac{24^2}{a^2}+\frac{9^2}{27^2}=1$

576/a^2 + 81/729 = 1 Subtract 81/729 from both sides
576/a^2 = 1 - 81/729 = 576/a^2 = (729 - 81)/729 = 648 /729

576/a^2 = 648/729 Cross multiply

648 a^2 = 729 * 576 Divide by 648
a^2 = 648

Full equation for the ellipse and answer is

$\frac{x^2}{648}+ \frac{y^2}{729} = 1$

Plz help been stuck on this for awhile

Kazeer [188]

Answer:

d = $\sqrt{74}$ or 8.60

Step-by-step explanation:

(5, 8) (-2, 3)

Let 5 = $x_{1}$

8 = $y_{1}$

-2 = $x_{2}$

3 = $y_{2}$

Plug in the values into the equation to get the distance:

d = $\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }$

d = $\sqrt{(-2-5)^{2} + (3-8)^{2} }$

d = $\sqrt{(-7)^{2} + (5)^{2} }$

d = $\sqrt{49 + 25}$

d =  $\sqrt{74}$ or 8.60

Rosie Belin worked these total weekly hours in four weeks of work: 45, 38, 42, and 43. Her job pays $14 for each hour worked. Wh

MatroZZZ [7]

Answer:

Add the total number of hours in the four weeks and multiply that with the hourly pay rate to find the total gross pay. Divide the total gross pay by 4 to find the weekly average gross pay. An employee may earn income from various sources. The total income is the sum of all the earnings and is called as.
