The answer is 2 solution.
#Solution
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola<span>. We determine as follows:
y = 2x^2 - 4x + 1
</span>
y = a(x – h)2<span> + k
</span>
y = 2(x^2 - 2x) + 1
y = 2(x^2 - 2x + 1) + 1 - 1
y = 2(x - 1)^2
Therefore, the line of symmetry passes through the vertex ( 1, 0) with an equation x = 1.

Answer:
5.29
Step-by-step explanation:
Pythagorean theorem is used
We will call AB x
x^2 + 6^2 = 8^2
x^2 + 36 = 64
x^2 = 28
x = 5.2915026
<u>x = 5.26</u>
Answer:
The kinetic energy of Mary is 20 Joules
Step-by-step explanation:
Given
Mass = 40 kg
Velocity = 1 m/s
Required
Calculate the kinetic energy.
The kinetic of any body is calculated by using the following formula.
K.E = ½mv²
Where K.E represent kinetic energy
m represent the mass of the body
v represent the velocity of the body.
To solve the kinetic energy, in this case, we simply substitute 40kg for m and 1m/s for v.
This gives us
K.E = ½ * 40 * 1²
K.E = ½ * 40 * 1
K.E = 0.5 * 40
K.E = 20
Hence, the kinetic energy of Mary is 20 Joules
