Answer:
(x + 3)² + (y - 7)² = 81
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 the radius
here (h, k ) = (- 3, 7 ) and r = 9 , then
(x - (- 3) )² + (y - 7)² = 9² , that is
(x + 3)² + (y - 7)² = 81
The answer is the first one

Answer: 8.4 miles per hour
Step-by-step explanation:
Since, total distance = 24.5 miles,
Time taken = ![175 \text{ minutes} = \frac{175}{60} \text{ hours} =\frac{35}{12} \text{ hours}](https://tex.z-dn.net/?f=175%20%5Ctext%7B%20minutes%7D%20%3D%20%5Cfrac%7B175%7D%7B60%7D%20%5Ctext%7B%20hours%7D%20%3D%5Cfrac%7B35%7D%7B12%7D%20%5Ctext%7B%20hours%7D)
Thus,
![\text{ The unit rate} = \frac{\text{ Total distance}}{\text{ Time taken}}](https://tex.z-dn.net/?f=%5Ctext%7B%20The%20unit%20rate%7D%20%3D%20%5Cfrac%7B%5Ctext%7B%20Total%20distance%7D%7D%7B%5Ctext%7B%20Time%20taken%7D%7D)
![=\frac{24.5}{35/12}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B24.5%7D%7B35%2F12%7D)
![=\frac{294}{35}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B294%7D%7B35%7D)
![=8.4\text{ miles per hour}](https://tex.z-dn.net/?f=%3D8.4%5Ctext%7B%20miles%20per%20hour%7D)
