For a quadratic of the form

, we complete the square by first adding

to each side.
Here, the coefficient b is equal to 10. We take half of this—5—and square it to get 25. We add this to both sides of the equation.
FYI, this equation can easily be factored, so there's no need to complete the square.
Again I have no idea the app brought me back to this question but try adding and dividing like I said before
It's A.
The value is increasing threefold relative to the previous step.
all other function values increase by a fixed amount and are therefore linear
Answer:
irrational and regular
Step-by-step explanation:
i looked it up
Solution :
Given :
Height of the tower , h = 45 m
Weight of the weather vane, mg = 190 N
So the potential energy possessed by the weather vane is given by
E = m x g x h
where, E is potential energy
m is mass
g is acceleration due to gravity (taken as 10 m/s2)
h is height
Therefore,
E = m x g x h
E = (mg) x h
E = 190 x 45
E = 8550 J
