An equivalent statement is CD overbar congruent to EF overbar.

What is a line segment?

The line segment has two fixed-length endpoints, A and B. The distance between this line segment's endpoints A and B is its length.

Here,

Line segment CD is congruent to line segment EF and in geometry, an overbar represents a line segment.

So, we can say that the CD overbar means line segment CD and the EF overbar means line segment EF.

Hence, An equivalent statement is CD overbar congruent to EF overbar.

The equation of the line is that passes through (1,4) and (3, -6) is

y = -5x + 9

First, write the equation in slope-intercept form:

y = mx + b

(the m is the slope, and b is the y-intercept)

Now, Lets find the slope(m) of the line by using the formula:

y2-y1/x2-x1

(-6 - 4)/ (3 - 1) = -10/2 = -5

Next, find the y-intercept (b) by using the slope-intercept form equation and substituting -5 in for m and one of the ordered pairs in for x and y:

4 = (-5)(1) + b

b = 9

-OR-

-6 = (-5)(3) + b

b = -6 + 15 = 9

b = 9

Now, we can write the full equation of the line:

Part A; The vertical to horizontal ratio of the ramp in the question of 3:15 does not meet the ADA guideline of a vertical to horizontal ratio of 1:12

Part B; The measurement of the ramp that would meet ADA guideline is a vertical to horizontal ratio of 3 feet to 36 feet.

The front entrance of the ramp should therefore be 36 feet away

A ratio  is an indication of the number of times one quantity is contained in another quantity.

The ADA guidelines requires that the rise angle ≤ 4.8°

The vertical ratio of the ramp ≤ 1:12

The distance the handicapped ramp must start = 15 feet from the front entrance

The rise of the ramp estimated by the contractors = 3 feet

Part A; The vertical to horizontal ratio of the ramp in the question = 3/15, which is 1:5

Therefore, the ramp does not meet ADA guidelines that requires a vertical to horizontal ratio of less than or equal to 1:12

Part B:

The ramp can be made to meet ADA guideline, whereby the horizontal distance from the entrance can be be adjusted as follows;

Let d represent the required horizontal distance of the front entrance, we get;

3:d = 1:12

From which we get;

[tex]\dfrac{3}{d} =\dfrac{1}{12}[/tex]

Answer

Option 1 is correct.

The graph could easily be the graph of a linear function.

Explanation

The points (2, 5) and (8, 5) can be seen to lie on the same line of y = 5

So, we can conclude that the graph could be a simple linear function, or a curve that passes this point twice.

So, option A is the only correct option here.

Hope this Helps!!!

The distance between point A and point B is 75.6 feet.

Let's set up a right triangle with the lighthouse at the top and the boat at points A and B at the bottom, with the base of the triangle being the horizontal distance between the two points.

We can then use the trigonometric function tangent to solve for the vertical distance between points A and B, which is given by the formula:

tan(angle of elevation) = vertical distance / horizontal distance

For point A, the angle of elevation is 8° and the horizontal distance is 1083 feet. So, the vertical distance from point A to the lighthouse is given by:

tan(8°) = vertical distance / 1083 feet

Solving for the vertical distance gives us:

vertical distance = tan(8°) * 1083 feet

For point B, the angle of elevation is 4° and the horizontal distance is still 1083 feet. So, the vertical distance from point B to the lighthouse is given by:

tan(4°) = vertical distance / 1083 feet

Solving for the vertical distance gives us:

vertical distance = tan(4°) * 1083 feet

Now we can find the distance between points A and B by subtracting the vertical distance from point A to the lighthouse from the vertical distance from point B to the lighthouse. This gives us:

distance between point A and point B = (tan(8°) * 1083 feet) - (tan(4°) * 1083 feet)

Plugging in the numerical values, we get:

Distance between point A and point B = (0.1403 * 1083 feet) - (0.0698 * 1083 feet)

Simplifying, we get: distance between point A and point B = 75.6083 feet

Therefore, the distance between point A and point B is 75.6 feet.

An elevation simply means the height above a particular place. It is usually referenced as the sea level.

In this situation, Melina is hiking and is at en elevation of 2000 feet. If she descends by 500 feet. It should be noted that since she descend, we will have to subtract 500 from the initial value that was given as 2000. feet.

Therefore, the calculation will be illustrated through subtraction. This will be:

What do you mean by angle?

Two straight lines or rays intersect at a same terminus to make an angle. The vertex of an angle is the point at which all points meet.

According to the data in the given question,

We have :

∠EFH=127°

∠EFG=(8x-4)°

∠GFH=(5x+14)°

Now, we have to solve the value of ∠GFH,

∠EFG+∠GFH=∠EFH

Putting the values given and solve for x,

(8x-4)°+(5x+14)°=127°

8x°-4°+5x°+14°=127°

13x°+10°=127°

13x°=127°-10°

13x°=117°

x=9

Then, putting the value of x in ∠GFH,

A translation transformation is a rigid transformation in which the location of the image obtained from the pre-image is different, but the dimensions are the same.

11) The transformation is similar to a rigid transformation

The change in coordinate is from (2, 2), to (4, 1), which is a translation 2 units to the right and -1 unit down

12) The shape is preserved and the length of the sides are also preserved, therefore, the transformation is a rigid transformation, with a change from (5, 3) to (0, 5), which is a translation 5 units to the left  and 2 units up.

13) The change in the coordinates from the pre-image to the image are from V(-3, 2) to V(-4, 5), which is a transformation of 1 unit to the left and 3 units up

14) The coordinates of a point on the pre-image is T(-5, 2), and the coordinates of the corresponding point on the image is T'(-5, 1), which is a translation of one unit downwards, [tex]T_{(0, \,-1)}[/tex]

15) A point on the pre-image is T(-3, -1), the corresponding point on the image is T'(0, 3), which indicates that the rule for the transformation is a translation of 3 units to the right and a vertical translation of 4 units upwards

16) The difference between the x and y values are;

Δx = 0 - 3 = -3

Δy = -3 - (-4) = 1

The transformation is therefore of the form [tex]T_{(-3, \,1)}[/tex], which is a translation of 3 units to the left and 1 unit upwards

17) The change in the x and y values are;

Δx = -2 - (-3) = 1

Δy = -3 - (-3) = 0

The rule of the transformation is therefore of the form [tex]T_{(1, \,0)}[/tex], which is a translation one unit to the right.

18) The change in the x and y values of the transformation are;

Δx = 1 - (-5) = 6

Δy = -4 - 1 = -5

The rule of the transformation is therefore, [tex]T_{(6, \,-5)}[/tex], which is a translation of 6 units to the right and 5 units down

19) The transformation of J(-5, 3), K(-3, 5), L(0, 1) to J'(-1, 3), K'(1, 5), L'($, 1) is a transformation of the form [tex]T_{(4, \,0)}[/tex] which is a horizontal translation 4 units to the right

20) H(-4, -3), I(-5, 0), J(-3, 0), K(-2, 1) to H'(-2, 1), 'I(-3, 4), J'(-1, 4), K'(0, 5) The transformation rule is [tex]T_{(2, \,4)}[/tex], which is a translation 2 units to the right and 3 units up

21) E(0, 1), F(-1, 5), G(0, 5), H(3, 2), to E'(1, -4), F'(0, 0), G'(1, 0), H'(4, -3), which is a transformation with the rule, [tex]T_{(1, \,-5)}[/tex], which is a translation one unit to the right and five units down

The population of the rabbit in 2009

Given that the population of rabbits on an island which is growing exponentially

So let the population be as P = P₀ [tex]e^{bt}[/tex]

where P₀ and b are constants and t = current year - 1994

In 1994, time is equal to 0

the population of rabbit , P = 9,600

so thus the expression becomes

P₀ = 9,600

and in 2000 , t = 2000 - 1994 thus time = 6 years and population of the rabbit is 18,400

[tex]18400 = 9600[/tex] × [tex]e^{b 6}[/tex]

18400 / 9600 = [tex]e^{b 6}[/tex]

23/ 12 = [tex]e^{b 6}[/tex]

Taking log on both sides

ln 1.92/ 6 = b

b = 0.109

On putting the value of P₀ and b the population of the rabbit after t years from 1994 is

P = 9600 × [tex]e^{0.109}[/tex] [tex]^{t}[/tex]

In 2009, t = 2009 - 1994 = 15 years

So, the population of the rabbit in 2009
