Answer:
Table A represents a function, but Table B does not represent a function.
Step-by-step explanation:
We have to select the correct option among the given 4 options after judging the given two tables attached to this question.
The first table shows that for each x values there is only one y value. Therefore, this is a function.
But in the second table shows that for each x value there are multiple y values since we are getting y = 1 and 2 for x = 5.
Hence, table B is not a function. it is just a relation. (Answer)

Step-by-step explanation:
A pilot is traveling at a height of 30,000 feet above ground she looks down at a angle of depression of 6 and spots runway as measured along the ground how many miles away is she from the runway
Distance between runway and pilot position along the ground is 285430.9336 feet that is 53.9464 miles.
Solution:Given that
Height of position of pilot from the ground = 30000 feet
Angle of depression when he looks down at runway = 6o
Need to measure along the ground, distance between runway and pilot that is horizontal distance between runway and pilot.
Consider the figure attached below
D represents position of runway.
P represents position of pilot.
PG represents height of position of pilot from the ground that means PG = 30000 feet
PH is virtual horizontal line and HPD is angle of depression means ∠ HPD = 6 degree
AS DG and HP are horizontals, so DG is parallel to HP.
=> ∠ HPD =∠ PDG = 6 degree [ Alternate interior angle made by transversal PD of two parallel lines ]
We need to calculate DG
Consider right angles triangle PGD right angles at G
[tex]\text {As } \tan x=\frac{\text { Perpendicular }}{\text { Base }}[/tex]
[tex]\tan \angle \mathrm{PDG}=\frac{\mathrm{PG}}{\mathrm{GD}}[/tex]
[tex]\begin{array}{l}{=>\mathrm{GD}=\frac{\mathrm{PG}}{\tan \angle \mathrm{PDG}}} \\\\ {=>\mathrm{GD}=\frac{30000}{\tan 6^{\circ}}=285430.9336}\end{array}[/tex]
As one foot = 0.000189 miles
[tex]=>285430.9336 \text { feet }=285430.9336 \times 0.000189 \text { miles }=53.9464 \text { miles. }[/tex]
Hence distance between runway and pilot position along the ground is 285430.9336 feet that is 53.9464 miles.
Final answer:
To find the distance to the runway, we can use trigonometry and create a right triangle using the pilot's height and the angle of depression. Using the tangent function, we can solve for the distance. The pilot is approximately 58.47 miles away from the runway.
Explanation:
To find the distance to the runway, we can use trigonometry. The angle of depression of 6 degrees tells us that the runway is below the pilot's line of sight. We can create a right triangle with the pilot's height of 30,000 feet as the opposite side and the distance to the runway as the adjacent side. Using the tangent function, we can solve for the distance:
Tan(6) = Opposite/Adjacent
Tan(6) = 30,000/Adjacent
Adjacent = 30,000/Tan(6)
Using a calculator, we find that the pilot is approximately 308,517 feet away from the runway.
To convert this distance to miles, we divide by 5,280 (since there are 5,280 feet in a mile):
308,517/5,280 ≈ 58.47 miles
Therefore, the pilot is approximately 58.47 miles away from the runway.

Answer:
The top cable is 115.52 feet long
The bottom cable is 110.86 feet long
Step-by-step explanation:
The ground anchor #2, the tower, ground level, and both cables form a figure made of two right triangles as shown in the figure below
We are required to compute L1 and L2 which are the hypotenuses of both triangles from which we have both legs
We'll apply the Pythagoras's theorem. If a and b are the legs of a right triangle and c its hypotenuse, then
[tex]c^2=a^2+b^2[/tex]
For the bottom ground support cable, a=41, b=103
[tex]L2^2=41^2+103^2[/tex]=110.86\ feet
For the top ground support cable, a=41, b=108

9. Wade has 126 inches of 1-inch wide bias tape for a border
on a rectangular banner. If the banner needs to be 48
inches long, what is the maximum width it could be?
Answer:
Let 'x' represent the width.
2*48 + 2x = 126
x = 15 in
The maximum width could be 15 inches.
Final answer:
To find the maximum width of the rectangular banner, calculate the total length of bias tape used, subtract it from the available bias tape, and divide the remaining inches by 2. The maximum width of the banner is 15 inches.
Explanation:
Maximum Width Calculation:
Calculate the total length of bias tape used: 48 inches x 2 sides = 96 inches.
Subtract the total length from the available bias tape: 126 - 96 = 30 inches.
Divide the remaining inches by 2 (since there are 2 widths): 30 / 2 = 15 inches.

How do you divide 3 1/4 and 3?
First we're going to change the 3 1/4 into an improper fraction.
3 1/4 is the same as 13/4
When dividing fractions, it's the same thing as multiplying by the reciprocal.
What this means is we're going to flip the second fraction.
So the original problem is this:
13/4 divided by 3/1
It now looks like this:
13/4 multiplied by 1/3
Then, simply multiply the top numbers together and then multiply the bottom numbers together.
13*1=13
4*3=12
your answer is 13/12

fire work a travels at the speed 300 ft/s firework b travels 240 ft/s. firework b is launched 0.25s before firework a. how many seconds after firework b launches will both fireworks explode?
Answer:
Both fireworks will explode after 1 seconds after firework b launches.
Step-by-step explanation:
Given:
Speed of fire work A= 300 ft/s
Speed of Firework B=240 ft/s
Time before which fire work b is launched =0.25s
To Find:
How many seconds after firework b launches will both fireworks explode=?
Solution:
Let t be the time(seconds) after which both the fireworks explode.
By the time the firework a has been launched, Firework B has been launch 0.25 s, So we can treat them as two separate equation
Firework A= 330(t)
Firework B=240(t)+240(0.25)
Since we need to know the same time after which they explode, we can equate both the equations
330(t) = 240(t)+240(0.25)
300(t)= 240(t)+60
300(t)-240(t)= 60
60(t)=60
[tex]t=\frac{60}{60}[/tex]
t=1
Final answer:
By setting the distance traveled by both fireworks equal, we find that both Firework A and B will explode 1.25 seconds after Firework B is launched.
Explanation:
To solve the problem of when both fireworks will explode, we can use the constant speed equation distance = speed × time. Firework A travels at 300 ft/s, and Firework B travels at 240 ft/s. Firework B is given a 0.25s head start. We need to find the time when they have traveled the same distance.
Let's call the time after Firework B launches when both explode as t. Since Firework A launches 0.25s after B, it will have traveled for t - 0.25s when they explode together. The equations for the distances traveled by both fireworks until that point will be:
Distance Firework A: 300 (t - 0.25)Distance Firework B: 240 tSetting these distances equal to each other:
300 (t - 0.25) = 240 t
Solving for t:
300t - 75 = 240t
60t = 75
t = 1.25s
Therefore, both fireworks will explode 1.25 seconds after Firework B launches.

Does the addition problem show a way to add 27 + 38?
Circle Yes or No for each addition problem.
a. 20 + 7 + 30 + 8 Yes No
b. 20 + 70 + 38 yes no
c. 20 + 30 + 7 + 8 Yes No
d. 50 + 10 + 5 yes no
Answer:
a. yes
b. no
c. yes
d. yes
Step-by-step explanation:
For a, 27 + 38 can be broken apart. 27 is broken up by adding smaller numbers (20 + 7 = 27) and the same is done with 38 (30 + 8 = 38), so A and C shows a way to add 27 and 38. In C, the numbers are just put into a different order. B is not a way to add 27 and 38, because the sum is different.
27 + 38 = 65, however 20 + 70 + 38 = 128. The addition problem for D is a way to solve for 27 + 38, because it is broken up differently than A and C. They instead added the 20 and 30 together first, then split up 15 (from 8+7) into 10 and 5. So D is a way to solve, because it gets the same answer as 27 and 38 :D

8 km + 2300 m +12,000 cm = ?
Answer:
The result is 10.42 kilometers, or 10,420 meters or 1'042,000 centimeters.
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
8 kilometers plus 2,300 meters plus 12,000 centimeters
2. Let's do the conversions to find the result either in kilometers, meters or even centimeters.
A. In kilometers:
8 kilometers
2,300 meters = 2.3 kilometers
12,000 centimeters = 120 meters = 0.12 kilometers
10.42 kilometers
B. In meters
8 kilometers = 8,000 meters
2,300 meters
12,000 centimeters = 120 meters
10,420 meters
C. In centimeters
8 kilometers = 8,000 meters = 800,000 centimeters
2,300 meters = 230,000 centimeters
12,000 centimeters
1'042,000 centimeters
The final sum is 10,420 meters.
To solve the mathematical problem of adding different units of measurement, we first need to convert everything to the same unit. In this case, let's convert all measurements to meters (m).
Convert 8 kilometers (km) to meters. Since 1 km = 1000 m => 8 km = 8 x 1000 => 8000 m.Convert 2300 meters (m) to meters. This is already in meters, so no conversion is needed and it remains 2300 m.Convert 12,000 centimeters (cm) to meters. Since 1 m = 100 cm, 12,000 cm = 12,000 / 100 = 120 m.Now, add these values together:
8000 m + 2300 m + 120 m = 10,420 meters

5. An $800 deposit for 24
months earned $200 in
interest
Answer:
The rate of interest applied fro compound interest is 24.5 %
The rate of interest applied simple interest is 37.5 %
Step-by-step explanation:
Given as :
The Principal amount that is deposited = $ 800
The Time period = 24 months = 2 years
The Interest earn = $ 200
Let the rate of interest = R %
So, The Amount = Principal deposited - interest earn
Or, A = $ 800 - $ 200
∴ Amount = $ 600
From compounded method
Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm Time}[/tex]
Or, $ 600 = $ 200 × [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]
Or, [tex]\frac{600}{200}[/tex] = [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]
Or, 3 = [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]
Or, [tex]3^{\frac{1}{2}}[/tex] = (1 +[tex]\frac{R}{100}[/tex])
Or, 1.245 = (1 +[tex]\frac{R}{100}[/tex])
or, 1.245 - 1 = [tex]\dfrac{R}{100}[/tex]
or, 0.245 × 100 = R
So, the rate is = 24.5 %
Hence The rate of interest applied fro compound interest is 24.5 % Answer
From Simple Interest method
Simple Interest = [tex]\dfrac{\textrm Principal\times \textrm Rate\times \textrm Time}{100}[/tex]
Or, $ 600 = [tex]\dfrac{\textrm 800\times \textrm R\times \textrm 2}{100}[/tex]
Or, $ 600 × 100 = $ 800 × R × 2
Or, R = [tex]\frac{60000}{1600}[/tex]
∴ R = 37.5 %
So, The rate is 37.5 %
Hence The rate of interest applied simple interest is 37.5 %Answer
