Answer:
x=1
Explain:
y=2x^2−4x+1
dy/dx=4x-4
The line of symmetry will be where the curve turns (due to the nature of the
x^2 graph.
This is also when the gradient of the curve is 0.
Therefore, let
dy/dx=0
This forms an equation such that:
4x−4=0
solve for x,
x=1
and line of symmetry falls on the line
x=1
1= 12.2
8=97.6
and for the last one the answer is 10 :))
Answer:
The square root is 5 units.
Step-by-step explanation:
It is given that:
Square area is 25 units square.
We have to find the square root.
Square root = 
Square root = 
Square root = 5 units
Therefore,
The square root is 5 units.
X=2.5
subtract 5 from both sides and then divide 5 by 2.
