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.

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.

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.

The mixed fraction can be 3 2/3 and the improper fraction would be 11/3 for the same mixed fraction.

A mixed fraction is one that is represented by its quotient and remainder. 2 1/3, for example, is a mixed fraction in which 2 is the quotient and 1 is the remainder. A mixed fraction is thus the product of a whole number and a proper fraction.

An improper fraction is one in which the numerator (top number) exceeds or equals the denominator (bottom number). Fractions like 651/14 are "incorrect." They are simply another way to write a mixed number.

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.

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.

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 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

Her average velocity is zero.

Given data:

The time taken by Amy is A=30 min.

The expression for the time taken by Julian is,

Substitute the given values in the above expression.

Thus, the time taken by Julian is 48 minutes.

Given that the radius r of a circle is written as a function of the area A with the following equation:

The domain of the above function is the area A of the circle.

This is because, in this context, the area is an independent and unique variable.

A is the input value.

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

polynomials

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.

That is the full solution.

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
