Is the sequence described as 3,5,8,12,17...... arithmetic. Explain your answer
Based on the sequence given of 3,5,8,12,17, it would be incorrect to say that the sequence is arithmetic. The sequence is not arithmetic.
What is an arithmetic sequence?In an arithmetic sequence, one would find that the number that separates each of the figures in the sequence is the same. In other words, the common difference between each figure is the same.
For instance, 2, 5, 8, 11, 14 has the common difference of 3 so this is an arithmetic sequence.
The sequence given of 3,5,8,12,17 is not arithmetic because the difference between each number is not common and instead increases.

Write the quadratic equation whose roots are 3 and 6, and whose leading coefficient is 2.
Which function in vertex form is equivalent to f(x) = x² + x +1?
Answer:
f(x) = (x + 1/2)² + 3/4
===============================
Vertex form of quadratic equation:
f(x) = a(x - h)² + kConvert the given expression into vertex form by completing the square:
f(x) = x² + x + 1 = x² + 2*(1/2)x + (1/2)² + 1 - (1/2)² = (x + 1/2)² + 1 - 1/4 = (x + 1/2)² + 3/4Answer:
[tex]f(x)=\left(x+\dfrac{1}{2}\right)^2+\dfrac{3}{4}[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{5.6 cm}\underline{Vertex form of a quadratic equation}\\\\$y=a(x-h)^2+k$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the vertex. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]
To find the vertex form of the given function, complete the square.
Given function:
[tex]f(x)=x^2+x+1[/tex]
Add and subtract the square of half the coefficient of the term in x:
[tex]\implies f(x)=x^2+x+\left(\dfrac{1}{2}\right)^2+1-\left(\dfrac{1}{2}\right)^2[/tex]
[tex]\implies f(x)=x^2+x+\dfrac{1}{4}+1-\dfrac{1}{4}[/tex]
[tex]\implies f(x)=x^2+x+\dfrac{1}{4}+\dfrac{3}{4}[/tex]
Factor the perfect square trinomial formed by the first three terms:
[tex]\implies f(x)=\left(x+\dfrac{1}{2}\right)^2+\dfrac{3}{4}[/tex]

Not true, true, true, true, true, true, true, not true, true, true
See explanation below
Explanation:From the diagram, we noticed a change in lengths when all four vertex was dragged.
This means the 4 sides will not always be the same (congruent).
Not always true: The four sides are congruent
From both diagrams. we found the opposite sides are the same (congruent)
Always true: The opposite sides are congruent
Since they opposite sides arecongruent, this also means the opposite sides are parallel
Always true: opposite sides are parallel
All four angles from both diagrams are equal (congruent)
Always true: all four angles are congruent
SInce all four angles areequal, then the angles opposite each other will also be equal.
Always true: opposite angles are congruent
The diagonals of both shapes bisect each other. Hence, they are congruent.
Always true: Diagonals are congruent
Always true: diagonals bisect each other
Diagonals of a square (the shapethat has all sides equal ) intersect at a right right angle.
Diagonals of a rectangle ( the shape with opposite sides equal) don ot intersect at right angle.
Not always true: Diagonals intersect at a right angle
The interior angles were split by the two diagonals in both shapes.
Always true: Diagonals bisect interior angles
The sum of angles in a quadrilateral is equal to 360°
Both shapes are quadrilaterals. Hence, the sumof their angles is 360°.
Always true: sum of all angles equal 360°

In the lab, Jane has two solutions that contain alcohol and is mixing them with each other. She uses 400 milliliters less of Solution A than Solution B. Solution A is 12% alcohol and Solution B is 20% alcohol. How many milliliters of Solution B does she use, if the resulting mixture has 176 milliliters of pure alcohol?
Answer:
700 ml of Solution B was used
Step-by-step explanation:
Whenever we have unknowns the first thing to do is to represent the unknowns using variables, set up equations using given information and solve equations for the unknowns
Here the unknowns are volume of solution A and volume of solution B
Set up our variables as follows
Let x = volume of solution A used for mixing in ml
Let y = volume of solution B used for mixing in ml
We are given that volume of A used is 400 ml less than volume of B used
In math terms this can be represented as
y - x = 400
Or,
- x + y = 400 [1]
We are given the percentages of alcohol in A and B respectively
Since A contains 12% alcohol, the actual volume of alcohol in A
= 12% of x ml
= 0.12x (12% = 12/100 = 0.12)
Similarly alcohol by volume in B
= 0.20x
Total alcohol by volume if x of A and y of B are mixed is
0.12x + 0.20y
and we are given that this quantity is 176 ml
So we set up our second equation as
0.12x + 0.20y = 176 [2]
Using both equations we eliminate either the x or y terms to arrive at an equation involving only the other term.
Since the question asks us to determine only the volume of Solution B used, we should eliminate x term from both equations to get a single equation involving only the y term
Let's review the equations:
- x + y = 400 [1]
0.12x + 0.20y = 176 [2]
Make the coefficients of x the same :
Multiply [1] by 0.12
=> -0.12x + 0.12y = = 0.12 x 400
=> 0.12x + 0.12y = 48 [3]
Add [2] and [3] to eliminate the x term
0.12x + 0.20y = 176
+
-0.12x + 0.12y = 48
-----------------------------------------
0x + 0.32 y = 224
=> 0,32y = 224
Divide both sides by 0.32
==> 0.32y/0.32 = 224/0.32
==> y = 700
So 700 ml of Solution B was used
If we wanted to find volume of solution A used, subtract 400 from 700 to get 300 ml of A

find the domain of f(x)=ln(cosx)
x ∈ ( -π/2 + 2kπ ; π/2 + 2kπ) ; k ∈ Z
The domain of f(x)=ln(cosx) = x ∈ ( -π/2 + 2kπ ; π/2 + 2kπ) ; k ∈ Z
Solution:The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f (x). A function's range is the set of values that the function can take.Given function,
f(x)=ln(cosx)
When cos(x) is positive, the domain is.
(cos(x)) > 0
since,
cos0 = 1
cos π/2 = 0
cos π = -1
cos 3π/2 = 0
cos 2π = 1
cos 3π/2 = 0
The values of cos(x) are then between -1 and 1.
That is domain of f(x)=ln(cos x)
= cos x ∈ (0;1] -> x ∈ ( -π/2 + 2kπ ; π/2 + 2kπ) ; k ∈ Z

What is a number?
A number is a mathematical entity that may be used to count, measure, and name things. The natural numbers 1, 2, 3, 4, and so on are the original instances. Number words can be used to represent numbers in language. Individual numbers can be represented more generically by symbols known as numerals; for example, "5" is a numeral that represents the number five. Because only a small number of symbols can be memorized, fundamental numerals are often structured in a numeral system, which is a systematic method of representing any number. The most prevalent numeral system is the Hindu-Arabic numeral system, which allows any number to be represented using a combination of 10 fundamental numeric symbols known as digits.
Let the number be n.
Then according to que, n + (5+n) = 17
or, 2n = 17 - 5
or, n = 12/2 = 6
Hence the number is 6.

Step 02:
applications of polynomials:
The polynomials can be represented graphically, and are used in many economics and engineering problems. In economics they appear, for example, to model markets, showing how prices vary over time; how raising or lowering the price of a product affects its sales; or also in the calculation of taxes.
In forestry engineering, for example, we need geometry to calculate areas, but also polynomials in problems such as calculating how many trees we need to replant after having cut down an area of a forest.
Other uses of polynomials are the calculation of the trajectory of projectiles (they are parabolic trajectories), or in the calculation of orbits of satellites or rockets.

If Amy Van swam her recordbreaking 50 m by swimming to one end of the pool, then turning around and swimming back to her starting position, what would her average velocity be
Answer:
zero
Step-by-step explanation:
You want Amy Van's average velocity when she swims 50 m to the end of the pool and back.
Average velocityAverage velocity is the ratio of the change in position to the amount of time over which that change occurs. When Amy ends up where she started, she has not changed position at all, so her average velocity is ...
Vave = (change in position)/time = 0/time = 0

Answer:
y = 3x+3
Step-by-step explanation:
The rate of change, or slope, in this case, is 3, as we can either count the increase in y-values or perform the Δy/Δx (slope equation: [tex]\frac{9-3\\}{2-0}[/tex])to yield three, meaning that the (3x) in this equation would be the slope. Since the y-intercept is the constant in the equation and the y-intercept is always when x=0 (when the graph crosses the y-axis) on the XY plane, we can just subtract 3 from the x=1 coordinate, meaning that the y-intercept/x=0 coordinate would be (0, 3), leaving 3 as the constant.
Therefore,
the equation is y = 3x+3.
