Part B: One of Mr. Iwan's students, Bret, wanted to add some more circles to the already plotted three and decided a circle should be
centered (-2,-2) with a radius of one unit. Graph Bret's new
circle.
Part C: Write the equation of Bret's new circle.
please help will mark brainliest for first person right

Given : Equation of three circles are given by Mr. Iwan to his students

To find : Circles need to be drawn on coordinate plane

Solution:

Equation of circle = (x - h)² + (y - k)² = r²

(h, k) - center of circle   & r = radius

Circle 1 :   x²  + (y + 4)²  = 36

(x - 0)² + (y -(-4))² = 6²

Center = ( 0 , - 4)    Radius  =  6

Circle 2 :   (x-5)²  + (y - 4)²  = 16

(x - 5)² + (y -(4))² = 4²

Center = ( 5 ,  4)    Radius  =  4

Circle 3 :   (x+5)²  + (y - 4)²  = 16

(x - (-5))² + (y -(4))² = 4²

Center = ( -5 ,  4)    Radius  =  4

the answer to this question is 3/19

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
