Here we have three similar triangles
In similar triangles sides are in proportion
The altitude to the hypotenuse of a right triangle is the mean proportional between the segments into which it divides the hypotenuse.
We cross multiply to solve for y
Taking root of both sides
y=8
C is the answer. It is the answer because the answer must be on the line or in the shaded area.
Answer:
It should be y=-1/2+(-1)
Step-by-step explanation:
For the given parabola, the axis of symmetry is x = 2.
<h3>
How to get the axis of symmetry?</h3>
For any given parabola, we define the axis of symmetry as a line that divides the parabola in two equal halves.
For a regular parabola, we define the axis of symmetry as:
x = h
Where h is the x-component of the vertex.
Remember that for the general parabola:
y = a*x^2 + b*x + c
The x-value of the vertex is:
h = -b/(2a)
Then for the function:
f(x)=−2x²+8x−2
We get:
h = -8/(2*-2) = 2
Then the axis of symmetry is x = 2.
