Answer:
2m 13s
Explanation:
1.5m = 1s
200m = × 1s
= 133s
= 2m 13s

Answer:
25kg
Explanation:
The formula for acceleration due to gravity is:
Here, G represents a constant and M represents the mass of the object. We don't need to know the actual values to solve this, then: We can just multiply by the amount they are multiplied relative to earth.
Multiplying this by the weight of the person on Earth of 40kg, you get 0.625*40=25kg.
Hope this helps!
Answer:
R=9.
C=(2,-2,0).
Explanation:
Lets try to find how can be written in the form of
, since then its radius R and center of coordinates C=(a,b,c) would be easily recognizable.
Since we have the terms -4x and +4y, they seem to have come from the terms and
, and we would need to take care of the extra +4 by substracting then. More explicitly:
, as we had originally with the x terms
, as we had originally with the y terms
Which means:
Or, putting all together:
So our radius is 9 and the center is (2,-2,0).
