Given: AC ⊥ BD and DB bisects ∠ABC.
Prove: △ABD ~ △CBD.

Answer:

m = 2 K.E / v^2

Step-by-step explanation:

K.E = 1/2 mv^2

K.E × 2/1 = mv^2

2 K.E = mv^2

2 K.E × 1/ v^2 = m

∴ m = 2 K.E / v^2

[tex]m=\frac{2KE}{v^{2}}[/tex].

Just for general knowledge. This is a formula from physics, specifically, classical mechanics. It is used to calculate the kinetic energy of bodies, that what the varaible "KE" stands for.

Now, let's rearrange the formula!

[tex]KE=\frac{1}{2} mv^{2}[/tex]

[tex]2KE=\frac{1}{2} mv^{2}*2\\ \\2KE=mv^{2}[/tex]

See that the 2 is used to cancel the 1/2 fraction.

[tex]\frac{2KE}{v^{2}} =\frac{mv^{2}}{v^{2} } \\ \\\frac{2KE}{v^{2}} =m\\ \\m=\frac{2KE}{v^{2}}[/tex]

[tex]m=\frac{2KE}{v^{2}}[/tex].

If the result is correct, then the equation should return the same value of both sides of the equal symbol (=) when we substitute the variable "m" by it's calculated value, [tex]\frac{2KE}{v^{2}}[/tex].

[tex]KE=\frac{1}{2} (\frac{2KE}{v^{2}})v^{2}[/tex]

Here, the 1/2 fraction is cancelled by the 2 inside the parenthesis. Also, the v² is cancelled out by the v² that's dividing inside the parenthesis, leaving us with this expression (check attached image to better understand this step):

[tex]KE=KE[/tex]

As you can tell, the same variable appears on both sides of the equal symbol, this means that the result is correct!

Answer:

a = 99

b = 51

Step-by-step explanation:

We can translate this problem into a linear equation. We know that:

2b - 3 = a

and

a + b = 150

We will start by minusing b from both sides in the second equation, giving us:

a = 150 - b

Then, we will substitute this into our second equation, giving us:

2b - 3 = 150 - b

We will add 3 and b to both sides, giving us:

3b = 153

Then we divide by 3:

b = 51

Now, we will substitute this into our second equation, giving us:

a + 51 = 150

Subtract 51 from both sides gives us:

a = 99

So, the a piece is 99 yards long, and the b piece is 51 yards long.

a = 99

b = 51

The measure of the tan of the angle T is 3.4286

From the question, we have the following parameters that can be used in our computation:

Opposite = RS

Hypotenuse = 50

Adjacent = 14

The opposite of the angle T can be calculated as

Hypotenuse² = Opposite² + Adjacent²

Substitute the known values in the above equation, so, we have the following representation

50² = RS² + 14²

Evaluate the like terms

RS² = 2304

Take the square root of both sides

RS² = 48

The measure of the tan of the angle T is then calculated as

tan(T) = RS/Adjacent

Substitute the known values in the above equation, so, we have the following representation

tan(T) = 48/14

Evaluate

tan(T) = 3.4286

Hence, the value is 3.4286

Answer: Roger should pick Printer B because it prints 2 more pages per minute.

Step-by-step explanation: We are given that printer A prints 33 pages per minute. We have to figure out how many pages printer B prints in a minute.

As shown in the table, in 2 minutes, printer B prints 70 pages, and in 3 minutes it prints 105 pages. We can create a function to model the rate at which printer A prints pages. This is a linear function since for each increase in x, there is a proportional increase in y. This means that if we were to back one minute the printer would print 35 pages since the common difference per minute is 35 pages. The function would therefore be p=35m where m=minutes and p=pages. This means that printer B produces 2 more pages than printer A per minute since 33+2=35.

The statement that complete the proof that quadrilateral EFGH is a square is; A) Line EF, FG, GH, and EH are congruent

The four sides of a square are always congruent to each other which means that they are equal to each other.

Now, we see that;

EF = 3√2

GH = 3√2

FH =3√2

EH = 3√2

Thus, all four sides are equal.

We also see that the slopes that form 90 degrees with each other are perpendicular and as such that is also a requirement for the quadrilateral to be a square.

Thus, we can conclude that all four sides are congruent to each other from the evidence above.

It is reasonable to assume that r = n rides. Since each ride costs $3 ($3xr), the total cost is $3.

In addition, we know that FIVE people, including Tory and every one of her friends, will be at the fair. The entrance fee is $7.50, therefore we can increase it by five to reach $37.5.

That is $3r plus $37.5.

A polygon will map to itself after a rotation of a 60° would be a regular hexagon.

What is a polygon?

A polygon is a closed, two-dimensional geometric shape that is defined by a set of straight lines, called its sides, that are connected end-to-end. The number of sides in a polygon is referred to as its "order" or "degree"

A polygon that maps to itself after a rotation of 60 degrees is called a regular hexagon. A regular hexagon is a polygon with six sides of equal length and six angles of equal measure (120 degrees each).

To sketch a regular hexagon, you can start by drawing a dot in the middle of a piece of paper. From there, use a compass or a straightedge to draw a circle around the dot. Then, use the compass to draw six lines from the center of the circle to the edge of the circle, each line being 60 degrees apart from the other. Finally, connect the endpoints of each line to form a six-sided polygon.

Hence, a polygon will map to itself after a rotation of a 60° would be a regular hexagon.

a. Yes, it is possible for a line (y = mx + b) that passes through the origin (0, 0) to pass through no other rational points. An example of such a line is y = sqrt(2)x. This line passes through the origin (0,0), but the y-coordinate will only be a rational number if the x-coordinate is also a rational number and a perfect square.

b. Yes, it is possible for a line to pass through no rational points. An example of such a line is y = sqrt(2)x + sqrt(3). This line will never pass through any rational points because the y-coordinate will only be a rational number if both x and b are rational numbers and perfect squares, which is not possible in this case.

We see that the y-intercept of the line is 4 while slope = -3/2.

The slope indicates the steepness of a line and the intercept indicates the location where it intersects an axis. The slope and the intercept define the linear relationship between two variables, and can be used to estimate an average rate of change.

The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept. In our equation, y = − 7 x + 4 , we see that the y-intercept of the line is 4.

The width of the flower bed is 3m.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Rectangular lawn = 8m x 4m

The flower bed dimensions are:

Length = (8m + x)

Width = x

The combined area of lawn and flower bed area = 140 m²

(8 + 2x) x (4 + 2x) = 140

32 + 16x + 8x + 4x² = 140

4x² + 24x + 32 - 140 = 0

4x² + 24x - 108 = 0

4 (x² + 6x - 27) = 0

x² + 6x - 27 = 0

x² + (9 - 3) - 27 = 0

x² + 9x - 3x - 27 = 0

x(x + 9) - 3(x + 9) = 0

(x + 9) (x - 3) = 0

x + 9 = 0

x = -9 (rejected)

x - 3 = 0

where [tex]b[/tex] is the length of the triangle's base and [tex]h[/tex] is the length of its height (altitude).

Both [tex]b[/tex] and [tex]h[/tex] are given to us for the shown triangle, so all we have to do is plug the given values into the triangle area formula above.

[tex]A = \dfrac{1}{2} \cdot 10 \cdot 25[/tex]
