Which equation represents a circle centered at (3,5) and passing though the point (-2,9)

Maru [420]

The equation represents a circle centered at (3,5) and passing through the point (-2,9) will be, $\rm x^2+y^2 -6x-10y-7=0$

What exactly is a circle?

It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.

Given data;

The Centre of the circle is,(h,k)=(3,5)

The circle traverses (-2,9). Consequently, the radius of the circle r is equal to the separation between (3, 4) and (-2,1).

So radius;

$r = \sqrt{{{(x_2-x_1)^2 + (y_2-y_1)^2}}$

$r = \sqrt{{(9-5)^2+(3+2)^2 }$

$r=\sqrt {41} \\\\ r =6.1 \ units$

Now equation of the circle with center (h,k) and radius r is

$\rm (x-h)^2 + (y-k)^2 = r^2\\\\ (x-3)^2 + (y-5)^2 = (\sqrt{41})^2\\\\ x^2 - 6x + 9 + y^2 - 10y + 25 = 41$

$x^2+y^2 -6x-10y-7=0$

Hence equation represents a circle that will be, $x^2+y^2 -6x-10y-7=0$

1) B. Yes, you want to begin saving at least 25 years before you plan to retire

2) D. all of the above

3) $2,341.27 per month realized income

4) Your housing and fixed expenses are $702.38 per month do you want to have a four month emergency fund and save it over a nine month period of time how much do you need to save per month?

Answer #4) $312.17 /month

Step-by-step explanation:

702.38 * 4 = 2,809.52 How much you will need to save for 4 months worth or expenses.

Now divide by 9 because that is how many months you will take to save up...

2,809.52 / 9 = 312.17

Answer) $312.17 per month, for 9 months to save 4 months worth or expenses.

Answer: 879.20 km²

<u>Step-by-step explanation:</u>

The diameter of the big circle is 2(10) + 18 = 38

divide the diameter by 2 to get the radius (r) = 19

Area (A) = π·r²

= π(19)²

= 361π

The diameter of the small circle is 18

divide the diameter by 2 to get the radius (r) = 9

Area (A) = π·r²

= π(9)²

= 81π

The area of the shaded region is the difference between the big circle and the small circle.

$Area_{shaded}=A_{big}-A_{small}$

= 361π - 81π

= 280π

= 280(3.14)

= 879.20
