A circle in the xy-plane is centered at (3, 0) and has a radius with endpoint (1, 8/3 ). Which answer choice is an equation of t
gayaneshka [121]

Answer: (x - 3)² + y² = \frac{100}{9}

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

Circle Formula: (x - h)² + (y - k)² = r²  ; (h, k) is the center & r is the radius

Use the distance formula for (3, 0) and (1, \frac{8}{3})

r = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

r = \sqrt{(3-1)^{2}+(0-\frac{8}{3})^{2}}

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

r = \sqrt{4+\frac{64}{9}}

r = \sqrt{\frac{36}{9}+\frac{64}{9}}

r = \sqrt{\frac{100}{9}}

r = \frac{10}{3}

****************************************************

Center (h, k) = (3, 0)   Radius (r) = \frac{10}{3}

(x - h)² + (y - k)² = r²

(x - 3)² + (y - 0)² = (\frac{10}{3})²

(x - 3)² + y² = \frac{100}{9}

A bicycle store costs ​$4200 per month to operate. The store pays an average of ​$75 per bike. The average selling price of each
Lelechka [254]

Store should sell about 31 bicycle for average price of $135 each bicycle.

Step-by-step explanation:

  • To find bike we need Algebra to solve the equation.
  • when x = 1 , Y = 135 *x
  • When x 2 , Y = 135 *2
  • Formula you could apply to go for break even y = 135*x
  • Bicycle store pays about $4200
  • Algebra used for every business and working to make easy task.
  • It takes about 31 bicycle a month to get into break even.
  • Every store needs break even to not incur lost.
  • Break even point is equilibrium between income and expenses.

= 0.043 x (10 x 3)

= 0.043 x 30

= <u>1.28</u>

2. 5 + (9) (6) - 4

= 5 + 9 x 6 - 4

= 5 + 54 - 4

= 59 - 4

= <u>55</u>
