Work = force * displacement
= 50 N * 20 Meter
=1000 Newton meter = 1000 joule .
Answer:
Step-by-step explanation:
The function y = 2x^2 + 4x has a parabolic graph that opens up.
*In factored form we have y = 2x(x + 2); if we set this equal to zero and solve for x, we obtain {-2, 0}, the roots of this function.
*The axis of symmetry is halfway between these roots: x = -1. The y-value of the vertex is the value of the function at x = -1: f(-1) = 2(-1)^2 + 4(-2) = -6. Thus, the vertex is (-1, -6).
* The y-intercept is (0, 0), since y = 0 when x = 0.
Graph the points shown and draw a smooth curve through them, remembering that this parabola opens up.
Answer:
The solution of the system of equations is (x,y) = (2,0)
Step-by-step explanation:
The equation of a line through the points 
and 
is equal to:
Where 
So, the equation of the line through the points (3, 1) and (–5, –7) is:
Then, we have two equations, y=x-2 and y=0.5x -1 , so solving for x, we get:
x - 2 = 0.5 x - 1
x - 0.5x = 2 - 1
x = 2
Replacing x=2 in the equation y=x-2, we get:
y =2 - 2 = 0
Finally, the solution of the system of equations is (x,y) = (2,0)
