Answer:
Approximately , assuming that .
Step-by-step explanation:
When the force is constant, moving by in the direction of the force would do a work of .
However, in this example, as an increasing portion of the chain gets lifted up, the force lifting the chain would increase in size. Hence, apply the integral form of this equation.
Let denote the force required to lift the chain when the height above the ground is meters. At that moment, exactly of the chain would be above the ground. The mass of that much of the chain would be the mass of the whole chain.
.
Integrate with respect to :
.
In other words, it would take approximately of energy to raise one end of the chain to that height of .
Answer: x=9,3
Step-by-step explanation:
-16 divided by 4 equals -4
565.32 rounded to the nearest ten is the place which has the 6. Therefore, we are seeing if 5.32 rounds up or down. Since 5.32 is greater than 5, it rounds to 10. Therefore, it rounds to 570.
Hope this helps!
Answer:
the answer for a is 38 over 45 that is the total fraction of her money that she spent in the local shop for b the answer is 7/45
This came about as for a when we added the total number of expenditures that CeCe had made that is 1/3 + 2/5 + 1/9 and that is 38/45 so that is the fraction of money that she said that she spent in the local shop.
as for b it said what fraction of sissies money does she have left and we know that the total fraction is 38 over 45 and we are going to subtract it from 1.
and that will give us 7/45
