Answer: correct option is C
The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.
Step-by-step explanation:
The total work done = P.E + K.E
K.E = 1/2mv^2
The speed V depends on the position:
0 < x < 5
Also, since work done = F × distance x
The workdone also depends on F(x)
The net force = 0 that is
F + fr = 0
Where fr = frictional force.
Therefore the best option for the hypothesis of work done will be;
The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.
Answer:
The last option y<4. Y is less than 4 since the shaded region is below 4 on the y Axis.
the slope is 9 and the y-intercept is - 2
the equation of a line in ' slope-intercept form ' is
y = mx + c ( m is the slope and c the y-intercept )
y = 9x - 2 is in this form
with slope m = 9 and y-intercept c = - 2
For this equation I would assume you use substitution, you plug in what y equals (3x -2), for the y in the second equation (4x - 4y = 8), you now have 4x - 4(3x-2) = -8 you then proceed to factor out this equation, you distribute the -4 and now you have 4x -12x + 8 = -8 you then subtract the -12x from the 4x and the result is -8x + 8 = -8, you then proceed to isolate the x subtracting the 8 from both sides and you now have -8x =-16 you then isolate the x by dividing -8 from both sides, your results are x = 2, you answer isn’t negative 2 because when you divide two negatives they cancel out creating a positive number.
