Answer:
About 30 min.
Step-by-step explanation:
Since it takes 10 min to walk a half of mile, it will take 20 min to walk a whole mile.
Since we will be walking one and a half miles, it should take about 30 minutes.
Hope this helps.
200000J/200KJ
Step-by-step explanation:
using k.e=1/2(mv2)
k.e=1×1000×20²/2
k.e=400000/2
k.e=200000J/200KJ
Answer:
(x + 3)² + (y - 1)² = 80
Step-by-step explanation:
Circle equation: (x - h)² + (y - k)² = r²
We are given <em>h</em> and <em>k</em>, so we just plug that in:
(x + 3)² + (y - 1)² = r²
To find <em>r</em>, we need to use distance formula: 
between the center of the circle and the point on the circle. We should get √80 as <em>r</em>. We plug that in to get our answer:
(x + 3)² + (y - 1)² = 80
The answer would be x equals all real numbers because you can't take the root of a negative number.
