Answer:

Option (D) is correct

(x-2)^{2} +(y+5)^{2} = 9

Step-by-step explanation:

A circle has (a , b ) are the coordinates of the centre and r = radius .

Given.

A circle is centered at (2,-5) and has radius 3

Let a=2 and b=-5 and r=3

The standard form of the circle is.

(x-a)^{2} +(y-b)^{2} = r^{2}------(1)

Put a, b and r value in equation  1.

(x-2)^{2} +(y-(-5))^{2}= 3^{2}

(x-2)^{2} +(y+5)^{2} = 9

So. the standard form of equation is.

(x-2)^{2} +(y+5)^{2}= 9

The sum of reciprocals of rehman’s ages 3 years ago and 5 years from now is 1/3. Find his present age
Afina-wow [57]

Answer:

His age is 7 years.

Step-by-step explanation:

Let Rehman's  present age be x years.

1 / (x - 3) + 1 /(x + 5) = 1/3

Multiply through by the LCD 3(x - 3)(x + 5):

3(x + 5) + 3(x - 3) = (x + 5)(x - 3)

3x + 15 + 3x - 9 = x^2 + 2x - 15

x^2 + 2x - 6x - 30 + 9 = 0

x^2 - 4x - 21 = 0

(x - 7)(x + 3) = 0

x = 7  (answer).
