Find the
28th term of
3,11, 19, 27
The 28th term of the given arithmetic sequence is 219
any arithmetic sequence can be solved once we identify the aa1 term and the an term because then we have to simply find the common difference and solve further by substituting the value in the below mentioned equation.
Given the arithmetic sequence = 3,11, 19, 27
a₁ = 3
a₂ = 11
a₃ = 19
a₄ = 27
the common difference or d = a₂ - a₁
this implies d = 11 - 3 = 8
Therefore the 28th term of the given arithmetic sequence is
a₂₈ = a₁ + ( n - 1 ) d
a₂₈ = 3 + ( 28 - 1 ) 8
= 3 + 27 × 8
= 3 + 216
= 219
Thus a₂₈ = 219

Hancox Homes Hancox Homes is a popular construction company that builds affordable housing. When the company first started, they sold 1 home the first month, 3 homes the second month, 9 homes the third month, and 27 homes the fourth month. What is the sequend pattern?
The sequence in the question may be given as
1, 3, 9, 27
From this, the first term is 1 and the common ration is 3
Common ratio = 3/1 = 9/3 = 27/9
= 3
a) Let U = {1,2, ., 9} be the universal set, and letA = {1,2,3,4,5),C= {5, 6, 7, 8, 9), E= {2,4,6,8),B = {4, 5, 6, 7),D= {1, 3, 5, 7, 9), F = {1,5,9}.Find: AUC'
Given:
U = {1, 2, 3, 4, 5, 6, 7, 8, 9}
A = {1,2,3,4,5}
B = {4, 5, 6, 7}
C = {5, 6, 7, 8, 9}
D= {1, 3, 5, 7, 9}
E= {2, 4, 6, 8}
F = {1, 5, 9}
What is the question: Find AUC'.
Recall the following:
A ∩ C (read as A intersection C) - are members that are common to both set A and set C.
A ∪ C (read as A union C) - are members that are in set A or set C or both, combining the members of all sets.
C' (read as C complement) - are members that are not in the universal set.
Since what we are about to find is A ∪ C', let's first determine the members of C'.
We get,
C' = {1, 2, 3, 4}
A = {1,2,3,4,5}
Therefore, AUC' = {1,2,3,4,5}.

The domain can be best described using interval notation. The domain is [1,∞].
A continuous function is graphed here. The function is continuous only on where it is defined. That is, the graph of the function does not have any discontinuities from 1 to infinity.
The domain of a function is the x-values for which the function is defined. That is for such x-values, the function will attain some y-value, which is called the function value. This function values corresponding to each x-value sketches the graph.
From the figure, the graph is started from x = 1 and is extended to infinity.

Find:
we have to find the function whose graph is a result of horizonal shift of 2 units of the original graph.
Explanation:
Since the given graph of the function is shifted 2 units horizontally,
and we know y is vertical axis, x is horizontal axis.
So put x = x+2 in the given function, we get
[tex]\begin{gathered} f(x)=(x+2-2)^2 \\ f(x)=x^2 \end{gathered}[/tex]Therefore the graph of f(x)=(x-2)^2 is a result of horizontal shift of 2 units of f(x) = x^2.

Mrs. Danforth packed $5$ bags of fun-sized candies for her family's picnic. Each bag contains $16$ pieces. She had intended to pass out the same number of candies to each of her $4$ children. But Cameron, her second-youngest, argues that she should instead distribute the candies in proportion to the children's ages. All of the children have different ages. If Cameron can convince his mother to give out the candies his way, he will gain two candies while his four-year-old sister will lose twelve. How old is Mrs. Danforth's oldest child?
From the information given in the word problem, the oldest child of Mrs. Danforth must be 13 years old.
What is the calculation showing the above?
Given:
Each bag contains $16 CandiesThere are 5 bagsThere are four children.Since the bags are distributed according to the proportion of their ages, then, we say
5 bags x 16 candies =80 candies.
80 / 4 = 20 candies per child
Given that his 4-year-old sister gets 20 -12 = 8 candies, then:
8/4 = 2 candies per year for each child's age.
Given that Cameron will gain 20 + 2 =22 candies, then:
22 / 2 = 11 years is Cameron's age.
22 candies of Cameron + 8 candies for youngest sister=30
80 - 30 = 50 candies for the remaining older children.
Since Cameron is the 2nd youngest, it means the remaining 2 siblings must be 12 and 13 years respectively:
So that: 12 x 2 = 24 candies for the 3rd oldest
And 13 x 2 = 26 candies for the oldest child. So, the total allocations of all the candies would be:
8 + 22 + 24 + 26 = 80 candies.
Therefore, the most senior child must be 13 years old.

The frequency for the given distribution of the class interval 1.00 - 1.09 is 3, which are 1.07, 1.05 and 1.07.
What is frequency?The frequency of a repeating event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to emphasise differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is expressed.
The period is the reciprocal of the frequency because it is the length of time for one cycle in a repeating event. For instance, the period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), is equal to 0.5 seconds (60 seconds divided by 120 beats).

What is area?
The measurement that describes the size of a location on a horizontal or contour is called area. Surface area refers to the area of an extended surface or the border of a tri object, whereas the area of a horizontal region or flat area corresponds to the area of a form or planar laminate. Area can be interpreted as both the amount of substance with a specific thickness required to create a model of the shape or as the quantity of paint required to completely cover a surface in a single coat. It is the two-dimensional equivalent of the volume of a solid or the length of a curve, both of which are one-dimensional concepts (a three-dimensional concept).

convert the following improper fraction to a mixed number-11/4
We are given the improper fraction
[tex]-\frac{11}{4}[/tex]And told to express it as a mixed number. To do so, we take the denominator (4) and look for the closes multiple of it that is less than the numerator (11).Then, we write the numerator as the sum of that multiple of the denominator and another number.
In this case, note that 4*2 = 8 and 4*3=12. So 8 is the multiple of 4 that is the closest to 11, such that it is less than 11.
In this case, we can write the following
[tex]\frac{11}{4}=\frac{8+3}{4}[/tex]Then, we can split the sum as follows
[tex]\frac{8+3}{4}=\frac{8}{4}+\frac{3}{4}=2+\frac{3}{4}[/tex]We see that there is one number that is not a fraction. This is the whole number of the mixed number. So we have
