The expression is Undefined for x=0, assuming you intend 1/(-8x).
x=0 is "nonpermissible"
Answer:
A
Step-by-step explanation:
Which segment shows what happens when x>2? What happens when x = 2 and which line shows it best. Which question is easier to answer?
It's not C or D.
Look at A. If x = 2 then -x + 4 = -2 + 4 = 2. I admit you can't let it be that way, but it gives you an indication of what to do. That is what happens to the short line on the right.
What is the long line doing? -2(2) - 1 = -5. Who does that? A does
So the Answer is A
Answer:
Hydrostatic force = 7800N
Step-by-step explanation:
The hydrostatic force is the force on a body when there is change its in hydrostatic pressure on the surface of the body when its equilibrium position shifts.
Let us first look at the formula for hydrostatic force
hydrostatic force = the pressure at the center x the area
Pressure = density x gravity x height
hydrostatic force = [sqrt(4)/2 m][1000 kg/m^3 * 9.8m/s^2] x [(1/2)(4)(4sqrt(4)/2) m^2]
Calculating the above data we get;
Hydrostatic force = 7800N
Answer:
N = -1/2
Step-by-step explanation:
We are adding in this, so we need to do the opposite to both sides, to get N by itself.
N + 3/4 - 3/4 = 1/4 - 3/4
N = -2/4 or, simplified, -1/2
