Answer:
No
Step-by-step explanation:
For a relation to be a function it must have a unique x-value for every y-value. This means that in a function x-values cannot repeat. In this relation, the x-value repeats multiple times, so it is not a function. It is also a vertical line, and vertical lines can never be functions since the x-value is constant and therefore repeats.
A billboard displays a large picture of a tire, draw to scale. The actual tire has a diameters of 40 inches. If the scale used for the picture is 1 3/4 feet equals 2 inches, what is the diameter of the tire, in feet, on the billboard? Plz I need it
Answer:
Diameter of the tire, in feet = 35 feet
Step-by-step explanation:
Given:
Actual diameter of tire = 40 inches
Scale; 1 3/4 feet = 2 inches
or
1.75 feet = 2 inches
Find:
Diameter of the tire, in feet
Computation:
Diameter of the tire, in feet = 40[1.75/2]
Diameter of the tire, in feet = 35 feet

Find the equation of the linear function represented by the table below in slope-intercept form.
Answer:
y=-5x+1
Step-by-step explanation:
First lets identify what slope intercept form looks like:
y=mx+b
m=slope
b=y-intercept
the y-intercept would be at (0,1)
choose 2 points from the graph and lets find the slope.
The formula for slope is:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1} }[/tex]
The points we will be using will be (1,-4) and (2,-9)
so -9 will be [tex]y_{2}[/tex] and -4 is [tex]y_{1}[/tex]
2 is [tex]x_{2\\}[/tex] and 1 is [tex]x_{1}[/tex]
set up the equation.
[tex]\frac{-9-(-4)}{2-1}[/tex]
[tex]\frac{-5}{1}[/tex]
m = -5
So the slope is -5 and the y-intercept is 1
[To find the y-intercept all you have to do is find what y is counting by. In this is would be -5. Go backwards one on the table so x is 0 and take away -5 and it will give you 1 which would be the intercept]
So the equation will be
y=-5x+1
Now when you want to solve it you plug in the x and y values for the table but it doesn't ask you to do that,
I've included a picture so you have a visual.

A triangle has angle measurements 24º and 85°. What is the measure of the remaining angle?
Enter your answer in the box.
Answer:
71 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180.
180 - 24 - 85 = 71.
The required measure of the remaining angle would be 71°
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbol. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.
A triangle has angle measurements of 24º and 85° which is given in the question.
The linear pair of angles are adjacent angles the sum of their measures is 180°
∵ The two angles form a linear pair
∴ The sum of the two angles = 180°
Let the measure of the remaining angle would be x
⇒ 24° + 85° + x = 180°
⇒ x = 180 - 24° - 85°
⇒ x = 71°.
Therefore, the required measure of the remaining angle would be 71°

The roof of the Terminal Tower is 709 feet above ground. A window washer dropped a bucket from the edge of the roof. How many seconds did it take for the bucket to hit the ground? Round to the nearest second
Answer:
6.64 seconds
Step-by-step explanation:
Given that:
Distance between roof of the terminal and ground = 709 feet
A bucket was dropped from the roof.
To find:
The time taken by the bucket to hit the ground?
Solution:
Distance traveled, [tex]s[/tex] = 709 feet
Initial velocity of the bucket, [tex]u[/tex] = 0 feet/sec (because initially it was at rest)
Acceleration of the bucket will be equal to acceleration due to gravity i.e.
[tex]g[/tex] or 32.1741 [tex]ft/sec^{2}[/tex]
Let the time taken is [tex]t[/tex] seconds.
Formula for distance is given as:
[tex]s = ut+\dfrac{1}{2}at^2[/tex]
Putting all the values:
[tex]709 = 0 (t) + \dfrac{1}{2}(32.1741) t^2\\\Rightarrow 1418 = 32.1741 t^2\\\Rightarrow t^2 = 44.07\\\Rightarrow t \approx \bold{6.64\ sec}[/tex]

Mrs Browns bill for servicing her car is £96 plus VAT. VAT is charged at 17.5%. What is her total bill?
_______________________________
T = V × P ÷ 100 + P= 17.5% × £96 ÷ 100 + £96= £112.8Mrs. Brown's Total Bill Is £112.8_______________________________
The total bill for servicing her car will be £112.8
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Mrs. Browns bill for servicing her car is £96 plus VAT.
And, VAT is charged at 17.5%.
Now,
Since, VAT is charged at 17.5%.
So, The VAT charge = 17.5% of £96
= 17.5 / 100 x £96
= £16.8
Hence, The total bill for servicing her car = £96 + £16.8
= £112.8
Thus, The total bill for servicing her car will be £112.8

What happens first when a star begins to run out of fuel?
The star’s core shrinks.
The star becomes a black hole.
The star becomes a white dwarf.
The star’s outer layer drifts away.
Answer:
a
Step-by-step explanation:
When a star begins to run out of fuel, the first thing that happens is that the star’s core shrinks.
Option A is the correct answer.
What is the star's core in an automobile?In the context of an automobile, the term "core" usually refers to a component of a vehicle's cooling system called the radiator core.
The radiator core is responsible for dissipating heat from the engine coolant by allowing air to flow through a series of metal fins attached to narrow tubes that carry the coolant.
We have,
When a star begins to run out of fuel, the first thing that happens is that the star’s core shrinks.
This is because the energy produced by nuclear fusion reactions in the core of the star is what keeps the star from collapsing under its own gravity.
As the fuel for these reactions runs out, the core of the star no longer has enough energy to counteract the force of gravity, causing it to shrink.
This in turn causes the outer layers of the star to expand, leading to the next stage in the star’s life cycle.
Thus,
The star’s core shrinks.

Graph the line that has a slope of 6 and includes the point (0,4).
Answer:
The equation of the line with slope 6 and containing the point (0, 4) will be:
[tex]y = 6x+4[/tex]
The graph of the line y = 6x+4 is attached below.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven
The slope m = 6The point (0, 4)The y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
The point (0, 4) indicates that:
at x = 0, y = 4
Thus, the y-intercept b = 4
now substituting b = 4 and m = 6 in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]y = 6x+4[/tex]
Thus, the equation of the line with slope 6 and containing the point (0, 4) will be:
