Answer:
(x - 5)² + (y + 3)² = 16
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (5, - 3) and r = 4, thus
(x - 5)² + (y - (- 3))² = 4², that is
(x - 5)² + (y + 3)² = 16 ← equation of circle

Answer:
Hence, the model that best represents the data is:
![y=26.9x-1.3](https://tex.z-dn.net/?f=y%3D26.9x-1.3)
Step-by-step explanation:
We are given a table that shows the estimated number of lines of code written by computer programmers per hour when x people are working.
We are asked to find which model best represents the data?
So for finding this we will put the value of x in each of the functions and check which hold true that which gives the value of y i.e. f(x) as is given in the table:
We are given 4 functions as:
A)
![y = 47(1.191)^x](https://tex.z-dn.net/?f=y%20%3D%2047%281.191%29%5Ex)
B)
![y=34\times (1.204)^x](https://tex.z-dn.net/?f=y%3D34%5Ctimes%20%281.204%29%5Ex)
C)
![y=26.9x-1.3](https://tex.z-dn.net/?f=y%3D26.9x-1.3)
D)
![y=27x-4](https://tex.z-dn.net/?f=y%3D27x-4)
We make the table of these values at different values of x.
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Hence, the function that best represents the data is:
Option C.
y=26.9x-1.3
