The equation of a circle is the equation that represents the circle on the coordinate plane

The equation of the circle is (x +3)^2 + (y -6)^2  = 13'

From the attached figure, we have the following parameters:

  • Center: (a,b) = (-3, 6)
  • Point on the circumference: (x,y) = (0,8)

Start by calculating the radius r using the following distance formula

d = \sqrt{(x -a)^2 +(y - b)^2}

So, we have:

r = \sqrt{(0 --3)^2 +(8 - 6)^2}

r = \sqrt{9 +4}

r = \sqrt{13}

Square both sides

r^2 = 13

The equation of the circle is then calculated as:

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

Substitute values for a and b

(x - -3)^2 + (y -6)^2  = r^2

This gives

(x +3)^2 + (y -6)^2  = r^2

Substitute r^2 = 13

(x +3)^2 + (y -6)^2  = 13

Hence, the equation of the circle is (x +3)^2 + (y -6)^2  = 13'

11 if you multiply 11 by both the number and and the variable you’ll get 11x-55=66. Add 55 to each side which will give you 121 then divide that by 11

Brilliant_brown [7]
For this case we have a function of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: growth rate
 t: time
 Substituting values we have:
 y = 1000 * (3) ^ ((1/8) * t)
 For 24 years we have:
 y = 1000 * (3) ^ ((1/8) * 24)
 y = 27000
 Answer:
 
D) 27,000; exponential

What is 93 divided by 7
igomit [66]
7 goes into 9, that's 1.
Remaining 2.

Move the 2 close to 3, you have 23.

7 into the 23, that's 3 times. 3 times 7 is 21.
So you are left with 2.

The answer is 13 remainder 2.
