A vertical straight line is not a function. It is a relation, but not a function as it does not follow the condition to be a function.
A condition for a function is that a unique input gives a unique output, that is a unique output can trace back to only one unique input.
In the case of a vertical straight line, it is of the form x = a, where a is a constant. That is for x = a, there is infinitely many values for y, therefore it does not follow the condition of a function and hence a vertical straight line is not a function.

Mr. Jackson has just finished building his treehouse and still needs to buy a ladder to be attached to the ledge of the treehouse and anchored at a point on the ground, as modeled below. Mr. Jackson is standing 1.3 meters from the stilt supporting the treehouse. This is the point on the ground where he has decided to anchor the ladder. The angle of elevation from his eye level to the bottom of the treehouse is 56 degrees. Mr. Jackson's eye level is 1.5 meters above the ground. Determine and state the minimum length of a ladder, to the nearest tenth of a meter, that Mr. Jackson will need to buy for his treehouse. (do not round until the very end)
Answer:
The length of the ladder Mr. Jackson will need to buy for his treehouse is approximately 3.7 meters
Step-by-step explanation:
The parameters given in the question are;
The horizontal distance from the point Mr. Jackson has decided to anchor the ladder to the the stilt supporting the tree house = 1.3 meters
The angle of elevation from Mr. Jackson's eye level to the bottom of the treehouse = 56°
The height of Mr. Jackson's eye level from the ground = 1.5 meters
From the question, we can draw the geometry of the ladder attached to the treehouse using Microsoft Visio as shown in the attached diagram
From the diagram, by trigonometric ratios, we have;
tan(56°) = a/1.3
∴ a = 1.3 × tan(56°) ≈ 1.927
By Pythagoras' theorem, we have;
The length of the ladder = √((a + b)² + 1.3²)
From the drawing, b = 1.5 m
Therefore, we have
The length of the ladder = √((1.927 + 1.5)² + 1.3²) ≈ 3.6653
The length of the ladder without rounding = √((1.3 × tan(56°) + 1.5)² + 1.3²) = 3.66559488352
∴ The length of the ladder given to the nearest tenth of a meter ≈ 3.7 m
The length of the ladder Mr. Jackson will need to buy for his treehouse ≈ 3.7 m.

Of the choices below, which unit of measurement would be most appropriate for measuring the volume of an ice chest? A. liters B. meters C. kilograms D. milliliters
Answer:
D. milimeters.
Step-by-step explanation:
Both meter and milimeter are length units. Kilogram is a mass unit. Liter is a volume unit, which is the cube of length in dimension terms. A liter equals 0.001 cubic meters or 1000000 cubic milimeters. Hence, the correct answer is D.
The area is approximately ___ square units.
Use 3.14 for π.
Answer:
A = 914 units
Step-by-step explanation:
The figure consists of a rectangle and a circle.
The sides of rectangle are 30 units and 20 units
The diameter of circle is 20 unit
Radius = 10 units
Required area = area of rectangle + area of circle
[tex]=l\times b+\pi r^2\\\\=30\times 20+3.14\times 10^2\\\\=914\ units[/tex]
So, the area of the figure is equal to 914 units.

Jean can pack 5 cartons in 15 minutes. Which expression can be used to show the number of cartons Jean can pack in x hours? Group of answer choices
Answer: 20x
Step-by-step explanation:
First we should note that 60 minutes = 1 hour. Therefore, 15 minutes = 15/60 = 1/4 hour
Since Jean can pack 5 cartons in 1/4 hours, the number of carton that he can pack in one hour will be:
= 5 ÷ 1/4
= 5 × 4
= 20 cartons.
Therefore, to get the number of cartons that Jean can pack in x hours, we will multiply 20 by x. This will be:
= 20 × x
= 20x
What’s the answer???
Answer:
The answer will be A
As 75 - 12 should be equal to 9x
So answer is "A"

Suppose the consumer group used a sample size of 50 instead of 100 for each airline. When all other things remain the same, what effect would the decrease in sample size have on the interval?
Answer:
Width of confidence interval will increase.
Step-by-step explanation:
The sample size as an effect on the width of the confidence interval being calculated as it determines the value of the error margin. In general, increasing the sample size reduces the width of the confidence that interval while decrease in its value increases the error margin and hence the confidence interval.
Confidence interval :
Xbar ± Error margin
Error margin = Tcrit * s/ sqrt(n)
n = sample size
Being the denominator, a decrease in its value will result in an increase in error margin.
What is the value of a missing angle
Answer:
63°
Step-by-step explanation:
First, by looking at the angle we see that the overall angle is a right angle. This means that the total will add up to 90°.
Knowing this we can then subtract
90° - 27° = 63°
Answer:
63
Step-by-step explanation:
The measure of a right angle is always 90 so
90-27=63
