The vertex form equation is y = (x-3)^2 - 14
The equation y = x^2-6x+5 is really the equation y = 1x^2-6x+5. It is in the form y = ax^2 + bx + c where
a = 1
b = -6
c = 5
We will use 'a' and 'b' in the formula below
h = -b/(2a)
h = -(-6)/(2*(1))
h = 6/(2)
h = 3
The h refers to the x coordinate of the vertex. Since we know the x coordinate of the vertex (is 3), we can use it to find the y coordinate of the vertex
Simply plug x = 3 into the original equation
y = x^2 - 6x + 5
y = -(3)^2 - 6(3) + 5
y = (9) - 6(3) + 5
y = +9-18+5
y = -4
This is the k value, so k = -4.
In summary so far, we have a = -1, h = 3 and k = -4. Plug all this into the vertex form below
y = a(x-h)^2 + k
y = 1(x-3)^2 -4
y = (x-3)^2 - 14
Therefore the vertex form equation is y = (x-3)^2 - 14

The distance between parallel celling and the floor is 10 ft.
The locus points are equidistant from the ceiling and the floor.
Required:
We need to find the distance between the locus plane and both the ceiling and the floor.
Explanation:
The locus of the points consists of the plane parallel to the floor and ceilings.
The locus plane is the midpoint of the distance between floor and ceilings since the locus points are equidistant from c
The mid-value of 10 feet is 5 feet.
The locus plane is 5 feet from both the ceiling and the floor.
Final answer:
The locus plane is 5 feet from both the ceiling and the floor.

Find the upper quartile of the first ten natural numbers.
Answer:
8
Explanation:
The first ten natural numbers are:
[tex]1,2,3,4,5,6,7,8,9,10[/tex]To find the upper quartile, separate the numbers into two halves:
• Lower Half: 1,2,3,4,5
,• Upper Half: 6,7,8,9,10
The upper quartile is the number in the middle of the upper half.
The number in the middle of the upper half = 8
Therefore, the upper quartile of the first ten natural numbers is 8.

In what they call “Year Zero," a group of 26 people started a settlement. Every yearthe population changes as babies are born, people move in, and people move out.Generally, the population increases by an average of 2.6 people a year.At the same time, a nearby established community discovered that their populationcould be described by the following function, where f(x) is the population, inpeople, and x is the time, in years, from "year zero."f(x) = -5.3x + 256Part AUsing your knowledge of functions, explain specifically why both communities' waysof expressing their populations represent functions. Provide evidence to supportyour answerPart BAnalyze the functions and compare the populations for the two communities overtime by describing in detail under what conditions one community's population isgreater than the other's population. Provide evidence to support your answer.
Solution
In the first paragraph,
It is given that a group of 26 people started a settlement and the population increased by an average of 2.6 people a year.
We can represent the population function as ;
g(x) = 26 + 2.6 x
Where x denotes the number of years and g(x) is the population after some certain years.
At a nearby community, it was discovered that the population can be written as;
f(x) = -5.3x + 256
Part A.
The population can be expressed as a function because the population at a particular time depends on the number of years x.
Specifically, it can be represented as a linear function because the rate at which the population increases per year is constant.
Part B.
Equating the functions
-5.3x + 256 = 26 + 2.6x
=> 5.3x + 2.6x = 256 - 26
=> 7.9x = 230
=> x = 29
Therefore, if the number of years is less than 29
The population of the first community will be less than the population of the second community
If the number of years is greater than 29
The population of the first community will be greater than the population of the second community

5g + h = g substract g both sides and substract h both sides too
5g - g = -h
4g = -h dive by 4 both sides
g = -h/g

probability experiment4.4 Given that a spinner lands on a prime number, find the probability that the arrow will land on an odd number.
To determine the probability of an event to occur, the formula is:
[tex]P(x)=\frac{noof\text{ favorable outcomes}}{no.\text{ of total possible outcomes}}[/tex]In the spinner, there are 6 possible outcomes. The arrow can either point from 1 to 6.
4.1. In the spinner, there are 3 prime numbers. These are 2, 3, and 5. Hence, there are 3 favorable outcomes if we want to have a prime number as a result after the spin. The probability of that happening will be:
[tex]P(x)=\frac{3}{6}=\frac{1}{2}=0.5[/tex]The probability of spinning a prime number is 1/2 or 0.5 or 50%.
4.2. We have already mentioned that there are 3 prime numbers (2, 3, 5). For odd numbers, we also have 3 and these are 1, 3, and 5. Combining the two, we get {1, 2, 3, 5} as either prime or odd numbers. As we can see, there are 4 favorable outcomes. Therefore, the probability is:
[tex]P(x)=\frac{4}{6}=\frac{2}{3}[/tex]The probability of spinning a prime number or an odd number is 2/3.
4.3. We have already mentioned that there are 3 prime numbers (2, 3, 5). For multiple of 3, we only have {3, 6}. Since the given operation is AND, that means, we have to find the intersection or what's common of both data. As we can see, only {3} is common. This means, only 3 is both a prime number and a multiple of 3. There is only 1 favorable outcome. The probability is:
[tex]P(x)=\frac{1}{6}[/tex]The probability of spinning a prime number and a multiple of 3 is 1/6.
4.4. If it has been already given that the number lands on a prime number, this means that we only have 3 choices or 3 possible outcomes. It's either 2, 3, or 5. Out of the 3 prime numbers, there are only 2 odd numbers and these are 3 and 5. Hence, the probability is:
[tex]P(x)=2\text{ out of 3}=\frac{2}{3}[/tex]Given that a spinner lands on a prime number, the probability of spinning an odd number is 2/3.

Given:
Center of the circle = P
Let's determine the following:
a) Radius.
Here, the radius of the circle is the hypotenuse of the triangle.
Therefore, the radius of the circle is 3 units
b) Center:
To find the point at the center of the circle, let's locate the point P on the graph.
On the graph, the point P is at (x, y) ==> (9, 4)
Therefore, the center (h, k) is (9, 4)
c) Value of a:
To find the value of a, let's first find the value of b.
Value of b = 6 - 4 = 2
Apply Pythagorean Theorem to find the value of a:
[tex]c^2=a^2+b^2[/tex]Where:
c is the hypotenuse = 3
b = 2

Explanation:
In order to add the mixed numbers given, we first convert the mixed numbers to improper fractions.
Now,
[tex]3\frac{7}{3}=3+\frac{7}{3}[/tex]The number 3 can be rewritten as
[tex]7=3\cdot\frac{3}{3}[/tex]which helps us rewrite our mixed fraction as
[tex]3+\frac{7}{3}=3\cdot\frac{3}{3}+\frac{7}{3}[/tex][tex]=\frac{9}{3}+\frac{7}{3}[/tex]adding the numerators gives
[tex]\frac{16}{3}[/tex]Hence,
[tex]3\frac{7}{3}=\frac{16}{3}[/tex]Similarly,
[tex]2\frac{5}{6}=2+\frac{5}{6}[/tex]the number 2 can be rewritten as
[tex]2=2\cdot\frac{6}{6}=\frac{12}{6}[/tex]therefore, the mixed number becomes
[tex]2+\frac{5}{6}=\frac{12}{6}+\frac{5}{6}[/tex][tex]=\frac{17}{6}[/tex]Hence,
[tex]2\frac{5}{6}=\frac{17}{6}[/tex]Now with mixed numbers rewritten as improper fractions, we are ready to add
[tex]3\frac{7}{3}+2\frac{5}{6}=\frac{16}{3}+\frac{17}{6}[/tex]rewriting 16/3 as 16/3 * 2/2 gives
[tex]\frac{16}{3}=\frac{32}{6}[/tex]therefore, we have
[tex]\frac{16}{3}+\frac{17}{6}=\frac{32}{6}+\frac{17}{6}[/tex]and now we just add the denominators to get
[tex]\frac{32}{6}+\frac{17}{6}=\frac{49}{6}[/tex]Hence,
[tex]3\frac{7}{3}+2\frac{5}{6}=\frac{49}{6}[/tex]which is our answer!
George is a salesperson in a jewelry store and earns $100 per week, plus 10% of his weekly sales. If George makes $425 in one week , what are his sales for that week? $5,250$4,250$4,000$3,250
Since George earns $100 per week plus 10% of his weekly sales
Assume that his weekly sales are $x
Then he earns 100 + 10% of x
Since he makes $425 in a week, then
[tex]\begin{gathered} 100+\frac{10}{100}\times x=425 \\ 100+0.1x=425 \end{gathered}[/tex]Subtract 100 from both sides
[tex]\begin{gathered} 100-100+0.1x=425-100 \\ 0.1x=325 \end{gathered}[/tex]Divide both sides by 0.1
