Step-by-step explanation:

Answer/Step-by-step explanation:

When twi straight lines intersect, they form 2 pairs of opposite vertical angles that are congruent.

In the diagram given, the following pairs of vertical angles are formed:

<c and 40°

<b and <d

<c = 40° (vertical angles are congruent)

<b and 40° are linear pairs. They are both supplementary. Therefore:

<b = 180° - 40

<b = 140°

<d = <b (vertical angles)

<d = 140° (substitution)

Answer:

1.05 × 10^-3

Step-by-step explanation:

The decimal number 0.00105 in scientific notation is  [tex]1.05 \times 10^{-3}.[/tex]

Scientific notation is a way to represent numbers that are either very large or very small.

It consists of two parts: the coefficient and the exponent.

The coefficient is a decimal number between 1 and 10, and the exponent indicates the power of 10 by which the coefficient is multiplied.

In the case of 0.00105, we can express it in scientific notation as [tex]1.05 \times 10^{-3}.[/tex]

The given trig function consist of trig values of common angles;

The values that represent the solution to [tex]\mathbf{cos \left(\dfrac{\pi}{4} - x\right)} = \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex], x ∈ [0, 2·π) are;

[tex]x = \left\{\dfrac{\pi}{2} , \, or \ \dfrac{3 \cdot \pi}{2} \right \}[/tex]

Reason:

The given function is presented as follows;

[tex]cos \left(\dfrac{\pi}{4} - x\right) = \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex]

Where;

x ∈ [0, 2·π)

We have;

cos(A - B) = cos(A)·cos(B) - sin(A)·sin(B)

[tex]cos \left(\dfrac{\pi}{4} \right) = \dfrac{\sqrt{2} }{2}, \ sin\left(\dfrac{\pi}{4} \right) = \dfrac{\sqrt{2} }{2}[/tex]

Which gives

[tex]cos \left(\dfrac{\pi}{4} - x\right) =\dfrac{\sqrt{2} }{2} \cdot cos \, x + \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex]

Therefore, we get;

[tex]\dfrac{\sqrt{2} }{2} \cdot cos \, x = \dfrac{\sqrt{2} }{2} \cdot sin \, x - \dfrac{\sqrt{2} }{2} \cdot sin \, x = 0[/tex]

cos x = 0

Therefore;

Where;

n = 1, 3, 5, ...

x ∈ [0, 2·π)

Answer:

A) -2x + y = 3

Step-by-step explanation:

The equation of the line that is perpendicular to the given line and passes through its y-intercept is -2x + y = 3.

We are given that;

The equation= 2x + 4y - 12

Now,

The given line is 2x + 4y - 12 = 0.

To find the slope of a line perpendicular to this line, we need to find the slope of the given line first.

Rewrite the equation in slope-intercept form which is given by:

y = mx + b

where m is the slope and b is the y-intercept.

2x + 4y - 12 = 0

4y = -2x + 12

y = (-1/2)x + 3

Hence, the slope of the given line is -1/2.

The slope of a line perpendicular to this line is the negative reciprocal of this slope which is given by:

[tex]m(perpendicular)[/tex] = -1/m = -1/(-1/2) = 2

To find an equation of a line that passes through the y-intercept of the given line and has a slope of 2.

The y-intercept of the given line can be found by setting x = 0:

2(0) + 4y - 12 = 0

y = 3

Hence, the y-intercept of the given line is 3.

The equation of a line with a slope of 2 and passing through (0,3) can be found using point-slope form which is given by:

y - y1 = m(x - x1)

where (x1,y1) = (0,3) and m = 2.

Substituting these values we get:

y - 3 = 2(x - 0)

y - 3 = 2x

y = 2x + 3

Therefore, by the equation answer will be -2x + y = 3.

Answer:

B

Step-by-step explanation:

From the figure, its clear that the compass drew arcs like below:

With A as centre, and more than half of the length of AB as radius, one arc is drawn.

With the same radius, with B as centre, another arc is drawn.

The points of intersections of the arcs are X and Y.

Clearly, this is the construction of a perpendicular bisector of the line segment AB.

Hence, if we draw a line segment through XY, it will be a perpendicular bisector of AB.

260 miles

Step-by-step explanation:

Sara made it to her destination in four hours, while Holly made it to her destination traveling 260 miles. This can be calculated by taking Sara's 200 miles, and dividing it by 50 mph to get a total of four hours spent driving. If Holly is also driving for four hours, but instead traveling at 65 mph, you can take 65 and multiply it by four hours to get a total of 260 miles. Hope this helps!
