Answer:
<em>The ball will roll upto </em><em>1 m.</em>
Step-by-step explanation:
A 1 kg ball has 10 joules of kinetic energy and starts to roll up a hill.
As along the hill the ball rises up, it loses its kinetic energy. The kinetic energy is converted to potential energy.
According to the law of conservation of energy, the kinetic energy plus the potential energy equals a constant.
Here given kinetic energy as 10 J, so this energy will get converted to potential energy.
We know that, potential energy is

where,
m is the mass, g is the acceleration due to gravity and h is the height.
Putting the values,



I think $8. That’s the difference between the highest and lowest number.
Answer:
The solution for given system of equation is:
and ordered pair is: 
So, (1,3) is not solution to the given system of equations.
Step-by-step explanation:
we can solve the system of equations to find the value of x and y and then verify if (1,3) is a solution or not.
The system of equation given is:

Solving:
Let:

Put value of y from equation 2 into equation 1

Now, put value of x in equation 2 to find value of y

So, the solution for given system of equation is:
and ordered pair is: 
So, (1,3) is not solution to the given system of equations.
Answer: (15/2, 33/2) or (7.5, 16.5)
depending on if you want fractions or decimals
explanation:
equation for midpoint... (avg x, avg y)
x-coordinate: (6+9)/2 = 15/2 = 7.5
y-coordinate: (17+16)/2 = 33/2 = 16.5
