Answer:34.3 N and 15.7 N
Explanation:
= force on the left end of the rod
= force on the right end of the rod
M = mass of Halloween decoration = 3 kg
= weight of the Halloween decoration = Mg = 3 x 9.8 = 29.4 N
m = mass of rod = 2.1 kg
= weight of the rod = mg = 2.1 x 9.8 = 20.6 N
From the force diagram, using equilibrium of torque about A
(AB) + (AC) = (AD)
(29.4) (21) + (20.6) (57) = (114)
= 15.7 N
Using equilibrium of force along the vertical direction
+ = +
15.7 + = 29.4 + 20.6
= 34.3 N

Step-by-step explanation:
a)
For each value of x, we need to solve for y.
Our equation is x² -2. This means that we multiply x by itself ( x * x = x²), and then subtract that value by 2.
Here is a list of the unfilled answers:
x = -2:
-2²-2 = -2 * -2 -2 = 4-2 = 2. -2 * -2 = 4 because two negatives multiplied together makes a positive.
x=-1:
-1²-2 = 1 -2 = -1
x=1
1²-2 = 1-2= -1
x=3:
3²-2 = 9-2 = 7
b)
In this graph, the y represents the vertical part and x represents the horizontal. For each value of y, there is a horizontal line that can be drawn. For example, when y=0, the bolded horizontal line near the bottom of the graph represents that. We then need to find the points on the line representing x²-2 where it touches the horizontal line of y=0. This happens when x=-1.5 and x=1.5, as it is between the positive/negative 1 and 2 values of x
Replace 1/8 into the equation for p and you get 2 - 10 which is -8
All of them
the roots of thhe equaiton are the x intercept
they would be at x=5 and x=-2
