The three properties of parallel lines are transitive property of parallel lines, symmetric properties of parallel lines and properties cut by transversal.

Properties of parallel lines when cut by a transversal

Two lines when cut by a transversal line are parallel if the corresponding angles so formed are equal. Generally, the corresponding angles are in relative positions and lie along the same side of the transversal.

Two lines cut by a transversal line are said to be parallel if the alternate interior angles so formed are equal. In general, the pairs of the alternate interior are found in the inner side but lie on the opposite sides of the transversal.

Two lines cut by a transversal line are said to be parallell if the alternate exterior angles so formed are equal. In general, the pairs of alternate exterior angles are found on the outer side but lie opposite each other.

Since the lengths of both diagonals are given by the square root of the sum of the squares of their coordinates, they have the same length. Therefore, the diagonals of a b c d are congruent.

Triangles with the same size, form, and arrangement are said to be congruent. This indicates that all three of the triangle' side lengths are congruent, or equal in size. Congruent triangles can be rotated or reversed, yet their congruence remains constant.

The Side-Side-Side (SSS) Congruence Postulate argues that if three sides of one triangle are identical in length to the corresponding sides of another triangle, the halves of are congruent.

If two angles and a side of one triangle are congruent to the corresponding angles and sides of another triangle, then the two triangles are congruent. As an alternative, one can apply the Angle-Side-Angle (ASA) Congruence Postulate.

How to solve?

The distance formula is given by d = √((x2 - x1)^2 + (y2 - y1)^2), where d is the distance between the two points, (x1, y1) and (x2, y2).

To find the length of diagonal a c, we plug in the coordinates of points a and c into the distance formula: d = √((c - 0)^2 + (d - 0)^2) = √(c^2 + d^2)

To find the length of diagonal b d, we plug in the coordinates of points b and d into the distance formula: d = √((a - 0)^2 + (b - 0)^2) = √(a^2 + b^2)

Since the lengths of both diagonals are given by the square root of the sum of the squares of their coordinates, they have the same length. Therefore, the diagonals of a b c d are congruent.

If p(x) and q(x) are arbitrary polynomials of degree at most 2 then

||p||||q|| = 26([tex]\sqrt{640}[/tex]) and angle between p(x) and q(x) is 0.233.

Given that

<p,q> = p(-1)q(-1) + p(0) q(0) + p(3)q(3)

and p(x) = 2x²+ 6 , q(x)= 4x²-4x

then the values of p and q at x = -1,0,3 are given as;

x = -1,

p(-1) = 2(-1)² + 6 = 8   ,    q(-1) = 4(-1)² - 4(-1) = 8

x = 0,

p(0) = 2(0)² + 6 = 6   ,    q(0) = 4(0)² - 4(0) = 0

x = 3,

p(3) = 2(3)² + 6 = 24  ,  q(3) = 4(3)²- 4(3) = 24.

<p,q> = p(-1)q(-1) + p(0)q(0) + p(3)q(3)

         = (8)(8) + (6)(0) + 24(24)

         = 64 + 0 + 576

<p,q> = 640

Now we have to find ||p|| ||q||, for this we'll find ||p|| and ||q||

||p|| = [tex]\sqrt{ < p,p > }[/tex]

     = [tex]\sqrt{8(8) + 6(6) + 24(24)}[/tex]

     = [tex]\sqrt{676}[/tex]

||p|| = 26

and

||q|| = [tex]\sqrt{ < q,q > }[/tex]

      =[tex]\sqrt{8(8) + 0(0) + 24(24)}[/tex]

||q||  =[tex]\sqrt{640}[/tex]

∴||p||||q|| = 26([tex]\sqrt{640\\[/tex])

Now we have to find angle between p(x) and q(x),

∴ α = cos⁻¹[tex]\frac{ < p,q > }{||p||||q||}[/tex]

      = cos ⁻¹ [tex]\frac{640}{26(\sqrt{640}) }[/tex]

The y-intercept of the given parabola is y = -12.

What is the y-intercept for the parabola?

A graph's y-intercept is the point at which the graph crosses the y -axis. (Because a function must pass the vertical line test, it can only have one y-intercept.) The y-intercept is frequently referred to simply as the y -value.

On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.

The given equation of the parabola is

                        y = x² - x - 12

To find the y-intercept of the given parabola we have to put x = 0 in the above equation, we get

                       y = (0)² - 0 - 12

                      y = -12

Hence, the y-intercept of the given parabola is y = -12.

and, the cost of running this ferry is $675.

To find the speed should it travel so as to minimize the cost per mile traveled.

Now, According to the question:

C(V) ∝ V³

then,

C(V) = KV³

When, C = 100 and V = 10

then, 100 = k[tex](10)^3[/tex]

=> k = 1/10

∴ [C(V) = [tex]\frac{V^3}{10}[/tex]]

As we know,

Total cost per hour,

[tex]C_1[/tex]  = [tex]\frac{V^3}{10}[/tex] + 675

Cost per mile = C/V

Now,

C₂ = [tex]\frac{\frac{V^3}{10}+675 }{V}[/tex]

=> [tex]\frac{V^2}{10} +\frac{675}{V}[/tex]

Then we'll need to discover their derivative as well as set that to zero (0) to minimize it.

[tex]C_2'[/tex],

=> [tex]\frac{2V}{10} - \frac{675}{V^2}[/tex] = 0

On applying cross-multiplication, we get

Thus, area of circle =[tex]\pi 18^{2}[/tex] = 324[tex]\pi[/tex]

Hence, the area of circle c, which passes though points w and z is 324[tex]\pi[/tex].
