The circle equation is in the format (x – h)2 + (y – k)2= r2, with the center being at the point (h, k) and the radius being "r".

x²+y²-8x-6y+2 =0 -----(a)
(x-4)² = x² - 8x + 16
(y-3)² = y² - 6y + 9

Equation (a) can be rewritten as:
(x-4)² + (y-3)² + 2 - 16 - 9 = 0
(x-4)² + (y-3)² = 23

The coordinates for the center of the circle is: ( 4,3)
The radius is √23=4.8

Step-by-step explanation:

Alright, lets get started.

Lets find slope for both bikes one by one

For bike 1 :

There are two points on the graph of Bike 1, these two points are (2,3) and (4,6)

So the slope for bike 1 is : $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

So the slope for bike 1 is : $\frac{6-3}{4-2}$

So the slope for bike 1 is : $\frac{3}{2}$

For bike 2 :

There are two points on the graph of Bike 2, these two points are (4,5) and (8,10)

So the slope for bike 2 is : $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

So the slope for bike 2 is : $\frac{10-5}{8-4}=\frac{5}{4}$

Hence Bike 1 will win the race as slope of line bike1 is greater than slope of line bike 2. So, answer is option D

Answer:

15% of 100,000 is 15000, so that would be 100,000 + (15,000*3) = 145,000 after 3 years.
