Answer:

Step-by-step explanation:

You have:

x^2+y^2-8x+27=0

Since the variable 'x' appears twice, I am going to choose to group together the terms as to create a 2nd degree trinomial:

(x^2-8x+27)+y^2=0

This allows us to complete the square and factor the trinomial:

(x^2-8x+16-16+27)+y^2=0

(x^2-8x+16)+11+y^2=0

(x-4)^2+y^2+11=0

(x-4)^2+(y-0)^2=-11

This is not a valid circle equation in the real plane. It has a complex radius of:

r=i\sqrt{11}

And is centered at the point:

(4,0)

Write the standard form of an equation of an ellipse subject to the given conditions.
irina [24]

Answer:

The answer is below

Step-by-step explanation:

The standard form of the equation of an ellipse with major axis on the y axis is given as:

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

Where (h, k) is the center of the ellipse, (h, k ± a) is the major axis, (h ± b, k) is the minor axis, (h, k ± c) is the foci and c² = a² - b²

Since the minor axis is at (37,0) and (-37,0), hence k = 0, h = 0 and b = 37

Also, the foci is at (0,5) and (0, -5), therefore c = 5

Using c² = a² - b²:

5² = a² - 37²

a² = 37² + 5² = 1369 + 25

a² = 1394

Therefore the equation of the ellipse is:

\frac{x^2}{1369}+ \frac{y^2}{1394} =1

kondaur [170]
The  2 lengths + 2 widths of the rectangle will equal 160 meters
So, for example,  length = 50 m and width = 30m  would fit the bill

2*50 + 2*30 = 160 m
