(04.01 MC) A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 10 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, 10) would represent a height of 10 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 0.75 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values. (3 points)
The ordered pairs, justification of the function with different order pairs is required.
The ordered pairs are [tex](0,10),(1,9.5),(2,9),(3,8.5),(4,8),(5,7.5)[/tex]
All values of [tex]x[/tex] has a unique value in [tex]y[/tex] so, it is a function.
y = Height of candle
x = Number of hours
m = Rate = 0.5 inches per hour
c = y intercept = Initial height = 10 inches
The required function is
[tex]y=-0.5x+10[/tex]
Six ordered pairs would be
[tex]x=0,1,2,3,4,5[/tex]
[tex]y=-0.5\times 0+10=10[/tex]
[tex]y=-0.5\times 1+10=9.5[/tex]
[tex]y=-0.5\times 2+10=9[/tex]
[tex]y=-0.5\times 3+10=8.5[/tex]
[tex]y=-0.5\times 4+10=8[/tex]
[tex]y=-0.5\times 5+10=7.5[/tex]
The ordered pairs are
[tex](0,10),(1,9.5),(2,9),(3,8.5),(4,8),(5,7.5)[/tex]
It can be seen that all values of [tex]x[/tex] has a unique value in [tex]y[/tex] so, it is a function.
If m = 0.75 inches per hour
The function would change to
[tex]y=-0.75x+10[/tex]
Some ordered pairs would be
[tex]y=-0.75\times 0+10[/tex]
[tex]y=-0.75\times 1+10[/tex]
[tex](0,10),(1,9.25)[/tex]
The same is seen in this function, all values of [tex]x[/tex] has a unique value in [tex]y[/tex] so, it is a function.

Answer:

Step-by-step explanation:
You want to choose the number line graph that appropriately represents the inequality 0 < x ≤ 26.
Graphing inequalitiesThe given compound inequality is conveniently written with the "arrows" pointing to the left. This means the lower limit of the variable is on the left side of the inequality, just as it is on the left end of the number line graph.
The inequality symbols used are "less than" (<) and "less than or equal to" (≤). The "less than" symbol is represented on a number line graph by an open circle. The "less than or equal to" symbol is represented by a filled dot on the number line.
This means you are looking for a graph that has an open circle on the left end of a solid line, and a filled dot on the right end. Only graphs B and C have finite-length lines, and only graph C has a filled dot at the right end.
Car seatsIn English, the word "between" often implies "and including" when it is describing an interval between two limits. Here, you are given 3 car seat specifications:
A: 0 < x ≤ 26 . . . . . up to 26 lbsB: 18 ≤ x ≤ 35 . . . . . between 18 and 35 poundsC: 26 ≤ x ≤ 75 . . . . . between 26 and 76 poundsThe seats appropriate for a 33-lb child would be seats B and C, because 33 is included in each of those intervals.

The mean of four number is 30. if three of the numbers are 12, 50, and 48 what's the fourth number?
Answer:
if the mean of 4 numbers is 30 then that means that the total of all the numbers added together must add up to 120 (30 x 4)
then you subtract the three numbers that you have from the total
120-12-50-48 = 10
so the last number is 10

The graph of y= 8x² + 7x - 5/5x² + 2x + 6 has a horizontal asymptote with equation (enter the equation of the horizontal asymptote)
The horizontal asymptote of the rational function y = (8 · x² + 7 · x - 5) / (5 · x² + 2 · x + 6) is y = 8 / 5.
How to determine the equation of a horizontal asymptote
A horizontal asymptote of a rational function is an horizontal line equations to which the rational function tends to when x tends to the infinite. The horizontal asymptote exists whether the lead grade of the numerator is not greater than the lead grade of the denominator.
Now we proceed to find the value of the horizontal function by using limit properties for rational functions:
y = 8 / 5
The horizontal asymptote of the rational function y = (8 · x² + 7 · x - 5) / (5 · x² + 2 · x + 6) is y = 8 / 5.

The National Science Institute was conducting research on the speed of Cheetahs. After
concluding their research, they were able to predict the cheetahs speed or distance when given
certain times or miles that the cheetah traveled. Complete the table of values and graph the
data on the coordinate plane.
Time(min) |. Distance(mi)
0. 0
1/2. 2/3
1. ?
? 3
8. ?
Answer the following questions using the information above.
1.) Is the relationship proportional? Why or why not?
2.) What is the unit rate?
The table of values is:
Time(min) | Distance(mi)
0 0
1/2 2/3
1 4/3
9/4 3
8 32/3
1) The relationship between Distance and Time is proportional.
2) The unit rate is 4/3 miles
To complete the table, we need to find the missing values of time and distance.
We use the relation between Distance, speed and time ,to find the missing values, which is given by,
Distance = Speed x Time
Given when time = 1/2 minute, the distance = 2/3 miles
Speed = Distance/Time
= 2/3 x 2/1
= 4/3 mile per minute.
This is the constant speed of the cheetah. We use this constant speed to find the other values to complete the table.
So If we take 'y' as the distance and 'x' as the time, then the relationship between time and distance can be expressed as
y = (4/3)x [since Distance = Speed x Time ].
So this relationship is proportional because there is a constant of proportionality 4/3 in the linear equation above and hence can be graphed as well.
The graph will contain the time values on the x-axis and distance values on the y-axis.
So now we need to find the missing values on the table using the above linear equation.
When time, x = 1 minute, distance, y = (4/3) x 1 = 4/3 miles.
When distance, y = 3 miles, 3 = (4/3)x
⇒ time, x = 3 x (3/4) = 9/4 minutes.
When time, x = 8 minutes, distance, y = (4/3) x 8 = 32/3 miles.
So the table is:
Time(min) | Distance(mi)
0 0
1/2 2/3
1 4/3
9/4 3
8 32/3
The unit rate refers to the y-value when the x-value is unity(1). So the unit rate here is found when time = 1 minute.
From the table, distance when time = 1 minute is 4/3 miles.
Hence, unit rate = 4/3 miles.

Burj Khalifa in Dubai is the tallest building in the world, standing at 828 meters. An adjacent
building, 100 meters away, stands at 550 meters tall. What is the angle of depression from Burj
Khalifa to the adjacent building?
Answer:
Approximately 70 degrees
Step-by-step explanation:
If we make a right triangle connecting the two buildings, we get a triangle with height 278m and length 100m
We can connect these two values to the theta by using the inverse tan formula
arctan(278/100) = 70.21572110836 degrees.
The angle of depression is approximately 70 degrees

Find the scale factor of trapezoid QRST if it’s dilated to Q’R’S’T’. Type your result in the empty box provided below. HELPP PLEASE!!!!!!
Answer:
5 units
Step-by-step explanation:
its hard to tell but i think it dilated 5 units
We want to find the scale factor at which QRST is dilated to form Q'R'S'T'
We will find that the scale factor is 2.
In a general dilation, we will see that all the measures change in the same way, by the scale factor.
This means that:
QR*k = Q'R'
RS*k = R'S'
And so on, where k is the scale factor.
Then we can just find one of the equivalent measures in both trapezoids and find the value of k.
For example, we have:
Q'R' = 8
QR = 4
Replacing these on the above equation we get:
4*k = 8
k = 8/4 = 2
k = 2
The scale factor of dilation is 2.
