Answer:
671080887.6
Step-by-step explanation:
1 second = 300,000km
3600 seconds = 3600 x 300,000 = 1080000000 km then convert to miles
is 671080887.6
The formula is (x-h)^2+(y-k)^2=r^2
so, using this, and knowing that h is -3 and k is -5 and r is 4, we get
(x--3)^2+(y--5)^2=(4)^2, which equals
(X+3)^2+(y+5)^2=16
