Given: AAEB and ADFC, ABCD, AE || DF, EB || FC, AC = DB
Prove: AEAB AFDC
By proving that ΔEAB and ΔFDC have congruent corresponding angles and proportional corresponding sides, we can conclude that ΔEAB ≅ ΔFDC.
Proving that Triangles are EqualGiven:
- Triangle ΔAEB and ΔDFC
- Line ABCD is straight (implies AC and BD are collinear)
- AE is parallel to DF
- EB is parallel to FC
- AC = DB
To prove: ΔEAB ≅ ΔFDC
Recall that:
AE || DF
EB || FC
AC = DB
AE || DF, EB || FC (Parallel lines with transversal line AB)
Corresponding angles are congruent:
∠AEB = ∠DFC (Corresponding angles)
∠EAB = ∠FDC (Corresponding angles)
Corresponding sides are proportional:
AE/DF = EB/FC (Corresponding sides)
AC/DB = BC/DC (Corresponding sides)
AC = DB
BC = DC (Equal ratios)
ΔEAB ≅ ΔFDC (By angle-side-angle (ASA) congruence)
∠EAB = ∠FDC
∠AEB = ∠DFC
AC = DB, BC = DC
Therefore, by proving that ΔEAB and ΔFDC have congruent corresponding angles and proportional corresponding sides, we can conclude that ΔEAB ≅ ΔFDC.

Stretched 1 cm beyond its natural length, a rubber band exerts a restoring force of magnitude 2 newtons. Assuming that Hooke's Law applies, answer the following questions:
(a) How far will a force of 3 newtons stretch the rubber band?
(b) How much work does it take to stretch the rubber band this far?
A) The distance that a force of 3 newtons would stretch the rubber band is; 0.015 m
B) The amount of work it takes to stretch the rubber band this far is; 0.0225 J
How to solve Hooke's Law?
From Hookes's law, as long as the elastic limit is not exceeded the extension is directly proportional to the force applied.
F = Ke
Where;
F = force
K = force constant
e = extension
Thus, for a restoring force of magnitude 2 newtons ;
2 N = K(1 × 10⁻²) m
K = 2 N /(1 × 10⁻²) m
K = 200 N/m
a) For a force of 3 newtons, we have;
3N = 200 N/m × a
Where a is the extension in meters
a = 3N/200 N/m
a = 0.015 m
b) The formula to find the work done is;
P.E = ¹/₂Ke²
P.E = ¹/₂ * 200 * 0.015²
P.E = 0.0225 J

Examine the following table. Determine whether the rate of change is constant or variable. If it is constant, state the rate of change.
Answer:
Variable rate of change.
Step-by-step explanation:
Plot the points and you'll see that the graph is not a straight line, therefore the rate of change is variable.
Rate of change is variable in the given data.
What is variable?"Variable is a quantity which shows the change in value as per the conditions apply on it."

Layla should by not more than 4 outfits in order not to exceed her budget
The inequality expression is n ≤ 4
price of a new bicycles = $418.55
2 bicycle reflectors = $19.39

The traffic lights at a certain intersection show red 55% of the time, yellow 10% and green the rest of the time.
If Sam drives through the intersection, what is the probability that the lights will not be green?
[Give your answer as a decimal].
The probability that the traffic light is not green is 0.65
What is the probability?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
If the traffic light is not green it can either be red or yellow.
The probability that the traffic light is not green = probability that the light is red + probability that the light is yellow
55% + 10% = 65% = 0.65

The largest species of jellyfish is the lion's mane jellyfish. One particular specimen has a diameter of 1.03 meters and tentacles that are 29 meters long. The specimen weighs 164 kilograms and can travel at a speed of 1.38 meters per second.
What is the diameter of the specimen in centimeters?
Answer:
The diameter of the specimen in centimeters is 103 cm.
Step-by-step explanation:
In order to determine the diameter in centimeters of the largest specimen of jellyfish, knowing that said diameter is 1.03 meters, and that 1 meter is equal to 100 centimeters, the following calculation must be performed:
1.03 x 100 = X
103 = X
Therefore, the diameter of the specimen in centimeters is 103 cm.
Which is the correct value of Z for the solution to true system?
2x+3y-z=4
x-3y+2z=-3
3x+y-z=5
The correct value of Z for the solution to true system is -2
How to determine the correct value of Z for the solution to true system?From the question, we have the following parameters that can be used in our computation:
2x + 3y - z = 4
x - 3y + 2z = -3
3x + y - z = 5
Transform the third equation
So we have
2x + 3y - z = 4
x - 3y + 2z = -3
9x + 3y - 3z = 15
Eliminate y in the equations by subtraction
So we have
x - 3z = 7
10x - z = 12
Multiply x - 3z = 7 by 10
10x - 30z = 70
10x - z = 12
Subtract the equations
-29z = 58
So, we have
z = -2
Hence, the correct value of Z is -2

At your imaginary house (in the future), you have a circular patio with a table in the center of the
circle. You are standing 5-feet from the table. You are also 13-feet from a point of tangency. What is
the approximate diameter of the circular patio?
Answer:
24 ft
Step-by-step explanation:
This is modelled as a right triangle with height 5 ft and hypotenuse 13 ft
Base of triangle = radius of circle
Find base length using Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs and c is the hypotenuse of a right triangle)
⇒ 5² + b² = 13²
⇒ 25 + b² = 169
⇒ b² = 169 - 25
⇒ b² = 144
⇒ b = √144
⇒ b = 12 ft
Therefore, if b is 12 ft, then the radius is 12 ft.
Diameter of a circle = 2r (where r is the radius)
⇒ diameter = 2 x 12 = 24 ft
Apply Pythagorean theorem
\(\\ \rm\hookrightarrow B^2=H^2-P^2\)
\(\\ \rm\hookrightarrow B^2=13^2-5^2\)
\(\\ \rm\hookrightarrow B^2=12^2\)
\(\\ \rm\hookrightarrow B=12\)

Given the triangle ABC at points A = ( 2, 2 ) B = ( 4, 5 ) C = ( 6, 3 ), and if the triangle is first reflected over the y axis, and then over the x axis, find the new point A''.
To reflect a point over the y-axis, we negate the x-coordinate of the point. To reflect the resulting point over the x-axis, we negate the y-coordinate of the point. So, to find the new point A'', we can perform these operations on the original point A:
1. Reflect A over the y-axis to get A': (-2, 2)
2. Reflect A' over the x-axis to get A'': (-2, -2)
Therefore, the new point A'' is (-2, -2).

The ratio of the measure of the vertex angle to the base angle of an isosceles triangle is 8:5. Find the measure of the vertex angle.(Please)
Answer:
Step-by-step explanation:
The two base angles are equal.
The vertex angle is 8x
The two base angles are 5x + 5x
The sum of all three angles = 180 degrees (all triangles make 180 degrees when their interior angles are added).
5x + 5x + 8x = 180
18x = 180
x = 180/18
x = 10
Therefore the vertex angle is 8*10 = 80 degrees
One of the base angles = 10* 5 = 50 degrees
The other base angle = 50 because the triangle is isosceles.

Answer
a. The backpack is $4.50
