A candle burns down at the rate of 0.75 inches per hour. The original height of the candle was 9 inches. Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points) Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points) Part C: If the rate at which the candle burned was 0.5 inches per hour instead of 0.75 inches per hour, would the relation be a function? Explain your answer using input and output values.

Which statement is not used to prove that ΔFGH is similar to ΔFIJ?
A. Angle F is congruent to itself, due to the reflexive property.
B. Angles FJI and FHG are congruent, due to the corresponding angles postulate.
C. Points F, J, and H are collinear.
D. Segments JI and HG are parallel.
Answer:
C. Points F, J, and H are collinear.
Step-by-step explanation:
Given
See attachment for triangle
Required
Which statement is false
Options A, B and D are true while C is false.
Two points are said to collinear if a straight line can pass through them.
From the attached triangle, we can see that a straight line cannot pass through F, J and H.
Hence, they are not collinear.
Since the statement is false, then it cannot be used as part of the proof.

SO MARK THE PERIMETER AND THE FORMULA FOR FINDING TRAPEZUIM IS
area=1/2 (a+b)h
Answer:
144 cm²
Step-by-step explanation:
5x + 12x + 6x + 5x = 56
=> 28x = 56
=> x = 2
DC => 6x = 6(2) = 12
AB => 12x = 12(2) = 24
BC => 5x = 5(2) = 10
AD => 5x = 5(2) = 10
trapezium is an isosceles trapezium because a trapezium with a pair of non-parallel sides(BC&AD) that have equal distances, which are congruent, is an isosceles trapezium.
Thus, the base of the two triangles on each side are congruent.
base: (AB - DC) ÷ 2 = (24 - 12) ÷ 2 = 6
calculate the height using Pythagorean theorem => √10² - 6² = 8
area of the isosceles trapezium ABCD: (12 + 24) × 8 ÷ 2 = 144

Answer:
The distance between the pirate and the treasure can be found from the following relationship between ΔEAF and ΔABC;
[tex]\overline{AE}[/tex]/[tex]\overline{AB}[/tex] = [tex]\overline{FA}[/tex]/[tex]\overline{AC}[/tex] = [tex]\overline{EF}[/tex]/[tex]\overline{BC}[/tex]
Step-by-step explanation:
From the question diagram, we have two triangles, ΔEAF and ΔABC;
The ratio of the lengths of the sides [tex]\overline{AE}[/tex]/[tex]\overline{AB}[/tex] = [tex]\overline{FA}[/tex]/[tex]\overline{AC}[/tex]
∠EAF and ∠BAC are vertical angles, therefore ∠EAF = ∠BAC
Therefore, ΔEAF and ΔABC are similar triangles by Side-Angle-Side, SAS, rule of similarity which states that two triangles that have ratios of a pair of their corresponding sides and the two sides also form equal angles within each triangle, then the two triangles are similar
Therefore, the ratio of the each pair of corresponding sides of the two triangles are equal
We have;
[tex]\overline{AE}[/tex]/[tex]\overline{AB}[/tex] = [tex]\overline{FA}[/tex]/[tex]\overline{AC}[/tex] = 50 ft. /(100 ft.) = [tex]\overline{EF}[/tex]/[tex]\overline{BC}[/tex] = [tex]\overline{EF}[/tex]/120 ft.
[tex]\overline{EF}[/tex] = 120 ft. × 50 ft./(100 ft.) = 60 ft.
[tex]\overline{EF}[/tex] = 60 ft.
The distance between the pirate and the treasure, [tex]\overline{EF}[/tex] = 60 ft.

Write the exact value of the side length of each square. If the value is not a whole number, estimate the length.
area exact side length estimite side length
100 square units ------ units
95 square units bettween ----- and -----
36 square units -------units
30 square units bettween ----- and -----
Given:
The area of the squares are given.
To find:
The exact side length or estimate side length of the square.
Solution:
We know that, the area of a square is
[tex]A=a^2[/tex]
Where, a is the side length of the square.
[tex]a=\sqrt{A}[/tex]
Area of the square is 100 square units. So, the side length is:
[tex]a=\sqrt{100}[/tex]
[tex]a=10[/tex]
Therefore, the side length is 10 units.
Area of the square is 95 square units. So, the side length is:
[tex]a=\sqrt{95}[/tex]
It is not exact. We know that [tex]\sqrt{81}<\sqrt{95}<\sqrt{100}[/tex].
Therefore, the side length is between 9 and 10.
Area of the square is 36 square units. So, the side length is:
[tex]a=\sqrt{36}[/tex]
[tex]a=6[/tex]
Therefore, the side length is 6 units.
Area of the square is 30 square units. So, the side length is:
[tex]a=\sqrt{30}[/tex]
It is not exact. We know that [tex]\sqrt{25}<\sqrt{30}<\sqrt{36}[/tex].
Therefore, the side length is between 5 and 6.

Consider the two points (1, 6) and (4, 48).

Answer:
Yes there is a line
y=14x-8
Step-by-step explanation:
use slope formula and incorporate the slope into the coordinates
Answer:
[tex]y = 14x - 8[/tex]
Step-by-step explanation:
. Using euclid postulate,
" any two points can be on a line".
So yes a line can be formed
Use the linear equation in ppont-slope form
[tex]y = mx + b[/tex]
where m is slope, b is the y intercept.
We can find the slope of the points first.
[tex]48 - 6 = 42[/tex]
[tex]4 - 1 = 3[/tex]
[tex] \frac{42}{3} = 14[/tex]
Our slope is 14.
We can plug in any two coordinates to find b.
[tex]14(1) - b = 6[/tex]
[tex] - b = - 8[/tex]
So our equation is
[tex]y = 14x - 8[/tex]

The mean of the 5 data is 51.
(55 + 60 + 35 + 90 + x) ÷5 = 51
(240 + x) ÷5 = 51
240 + x = 255
x = 15
10.
The mean of the 5 data is 127.
(100 + 112 + 98 + 235 + x) ÷5 = 127
(545 + x) ÷5 = 127
545 + x = 635
x = 90
12.
The mean of the 5 data is 40.
(34 + 56 + 45 + 29 + x) ÷5 = 40
(164 + x) ÷5 = 40
164 + x = 200
x = 36

Step-by-step explanation:
Jesse sent an email to 4 people for a school project. In her email, she requested that each person copy and send the same email to 4 additional people.If everyone continues to send the email as requested, which equation could be used to determine the number of emails, y, that will be sent for a given round, x?
M. y = x^4
P. y = 4^X
R. y = 4x
S. y = 4/X
Answer:
The equation could be used to determine the number of emails, y, that will be sent for a given round, x, is:
P. y = 4^XStep-by-step explanation:
To obtain the equation you must know how many emails will be sent in each case, taking into account that Jesse requested that each person copy and send the same email to 4 additional people, then:
First round: Jesse's emails = 4Second round = 16 = 4*4Third round = 64 = 16*4Fourth round = 256 = 64*4How you can see, each round is the same that to multiply the last sent emails by four, so, with the equation selected in the answer we can obtain these results:
y = 4^XIn the first round:
y = 4^(1)y = 4In the second round:
y = 4^(2)y = 16In the third round:
y = 4^(3)y = 64And, in the fourth round:
y = 4^(4)y = 256By this reason, the equation y = 4^X is the correct answer.
