Answer:
No; the graph fails the vertical line test.
The vertical line test is a tool used to determine if we have a function. If we can draw a single straight vertical line through more than one point on the red curve, then the graph is said to have failed the vertical line test. Consequently, this leads to the relation not being a function.
For this circle graph, we can draw a vertical line through more than one point, which is why we don't have a function here.
Put another way, there are inputs (x) that produce more than one output (y), so that's why we don't have a function.

A lithium atom has 3 protons, 4 neutrons and 3 electrons. How would the atom change to become a cation? How would the atom change to become an anion?
Answer:
- For the lithium ion to change to become an anion, it will have to gain one or more electrons which can be pulled away from possibly other atoms with a weaker affinity for them.
- For the lithium ion to change to become a cation, it will have to loose one or more electrons which can be drawn by other atoms with a stronger affinity for them.
Explanation:
Generally, an anion has a net negative charge arising from the fact that it has more electrons than protons while a cation has a net positive charge arising from the fact that it has more protons than electrons.
Now, for the lithium ion to change to an anion, it means it has to have more electrons than it's protons. Thus, since it has 3 number each of protons and electrons, it will have to gain one or more electrons which can be pulled away from possibly other atoms with a weaker affinity for them.
Now, for the lithium ion to change to a cation, it means it has to have more protons than it's electrons. Thus, since it has 3 number each of protons and electrons, it will have to loose one or more electrons which can be drawn out by possibly other atoms with a stronger affinity for them.

At highway speeds, a particular car is capable of an acceleration of about 1.6 m/s?. At this rate,
does it take the car to speed up from 80 km/hr to 110 km/hr? Round your answer to
Two significant figures
Given parameters:
Acceleration of the car = 1.6m/s
Initial speed = 80km/hr
Final speed = 110km/hr
Solution:
Time taken to achieve this speed = ?
Solution:
Acceleration is the rate of change of velocity with the time taken.
Mathematically;
a = [tex]\frac{V - U}{T}[/tex]
where a is the acceleration
V is the final velocity
U is the initial velocity
T is the time taken
Now make the unknown time the subject of the expression;
aT = V - U
T = [tex]\frac{V - U}{a}[/tex]
Convert the given acceleration to km/hr;
1.6m/s = 1.6 x [tex]\frac{m}{s}[/tex] x [tex]\frac{1km}{1000m}[/tex] x [tex]\frac{3600s}{1hr}[/tex] = 5.76km/hr
Input the parameters and solve;
T = [tex]\frac{110 - 80}{5.76}[/tex] = 5.2hrs
The time taken is 5.2hrs

A large bottle contains a number of medicinal tablets each having a mass of 250
mg. The mass of all the tablets is 1 kg. Calculate the number of tablets in the bottle.
Given parameters:
Mass of each tablet = 250mg = 0.25g
Mass of all tablets in the bottle = 1kg = 1000g
Unknown:
Number tablets in the bottle = ?
Solution:
The number of tablets in the bottle;
Number of tablets = [tex]\frac{mass of all tablets in the bottle}{mass of each tablet}[/tex]
Mass is the amount of matter that makes up a substance
Number of tablets = [tex]\frac{1000g}{ 250 x 10^{-3} }[/tex] = 4000 tablets
Considering the rule of three, the number of tablets in the bottle is 4.
In first place, the rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied.
To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{cxb}{a}[/tex]
The direct rule of three is the rule applied in this case as follow: if 250 mg = 0.250 g is the mass of 1 medicinal tablet, 1 kg = 1000 g is the mass of how many medicinal tablets?
0.250 grams ⇒ 1 medicinal tablet
1000 grams ⇒ x
Then:
[tex]x=\frac{1000 gramsx1 medicinal tablet}{0.250 grams}[/tex]
x= 4 medicinal tablets
Finally, the number of tablets in the bottle is 4.
