Answer:2250 miles
Step-by-step explanation:
If the jet travels 500 miles in an hour then in 4 hours it will travel 2000 miles. In half an hour it will travel 250 miles.
2000+250=2250 miles
The circle equation is in the format: (x – h)^2 + (y – k)^2 = r^2
<span>The center is at the point (h,k) and the radius is r
In the equation (x+8)^2+(y-2)^2=25,
</span>Center = (-8, 2)
Radius = 5
Hope this helps. :)
