The nth term in the sequence 3,9,15,21 will be 3 + 6(n - 1).

It should be noted that a sequence simply means the order in which a particular thing happens or takes place.

From the information, four term in the sequence are given as 3,9,15,21 and we want to find the nth term. It should be noted that this is an arithmetic sequence.

The formula is illustrated as:

= a + (n - 1)d

where a = first term = 3

common difference = 9 - 3 = 6

The nth term will be:

= 3 + (n - 1)6

= 3 + 6(n - 1).

The coordinates of the vertices of A'B'C' for the reflection are (7,1),(5,-7), and (-2,1) respectively.

A reflection is a transformation that uses a line to reflect a figure, much like a mirror. The mirror line is also known as the line of reflection.

The given coordinates are A(7,-5), B(5,3), and C(-2,-5).

The line of reflection is y = -2.

We have to determine the coordinates of the vertices of A'B'C' for the reflection.

In this case, the x-coordinate will remain the same and the y-coordinate will vary as the points are reflected across the line y = -2.

From the line of reflection i.e.y = -2, point A(7,-5) is located down at a distance of 3 units so its reflection A' is 3 units up of line y = -2 at (7,1).

From the line of reflection i.e.y = -2, point B(5, 3) is located up at a distance of 5 units so its reflection B' is 5 units down of line y = -2 at (5,-7).

From the line of reflection i.e.y = -2, point C(-2,-5) is located down at a distance of 3 units so its reflection C' is 3 units up of line y = -2 at (-2,1).

Hence, the coordinates of the vertices of A'B'C' for the reflection are (7,1),(5,-7), and (-2,1) respectively.

Answer:

78m^3

Step-by-step explanation:

basically you have to split it into two rectangles and add the volumes

so think of it like this (first picture)

- looking at the bigger rectangle (blue rectangle) the 6 and the 4 are there as hints to the smaller rectangle so just kind of disregard them

- basically the bottom length is 6 but the top length is 5 and this is because the bottom length includes the other rectangle (smaller/pink rectangle), meaning the extra length from the other rectangle (smaller/pink rectangle) is 1.

- then height is given as 4 and 5. the height of 4 is caused by the line stopping when it meets the pink/smaller rectangle, meaning that the height from the other rectangle (smaller/pink rectangle) is 1.

- so using the correct measurements, the height is 5, the length is 5, and the width is 3 so:

5 • 5 • 3 = 75

~ so as stated above from evaluating the different measurements and how the rectangles “intersect” or meet:

the height is 1, the width is 1, and the length is then given as 3 so:

1 • 1 • 3 = 3

so then 75 + 3 = 78

so the full volume is 78 m^3

Four siblings whose ages are consecutive odd integers. If the sum of their ages is 112 then The eldest sibling is 31, followed by siblings 29, 27, and 25.

What is consecutive integers ?

Consecutive means in order.  Integers are a collection of whole integers and their antipodes, such as -3, -2, 1, 0, 1, 2, 3, etc.

Let x = the 1st sibling

Let x -2 = the second sibling

Let x -4 = the third sibling

Let x-6 = the fourth sibling.

If you add the four siblings together they equal 112

(x) +(x-2)+(x-4)+(x-6) = 112  Combine like terms

4x - 12 = 112

add 12 from both sides

4x - 12 + 12 = 112 + 12

4x = 124

divide 4 both side :

x = 31

The eldest sibling is 31, followed by siblings 29, 27 and 25

Step-by-step explanation:

The rate of change for the height of the ice cream is [10 - (2π / 3) · (1 / 14) · h] / [(π / 3) · r²] units per second.

The volume of an ice cream cone (V), in cubic units, is described by the following formula:

V = (1 / 3) · (π · r²) · h                                     (1)

Where:

The rate of change for the height of the cone is derived from differentiating (1) with respect to time:

V' = (1 / 3) · (2π · r) · h · r' + (1 / 3) · (π · r²) · h'

V' = (2π / 3) · h · r' + (π / 3) · r² · h'

h' = [V' - (2π / 3) · h · r'] / [(π / 3) · r²]

Where:

If we know that V' = 10 and r' = 1 / 14, then the rate of change for the height of the cone is:

h' = [10 - (2π / 3) · (1 / 14) · h] / [(π / 3) · r²]

The height of the ice cream cone changes at a rate of [10 - (2π / 3) · (1 / 14) · h] / [(π / 3) · r²] units per second.

12 - 10 - 2 = 0

90 + 70 = 160

Put them "as an equation": 10x + 160 = 360

Answer:he graph shows the relationship between the number of miles she drives, y, and the number of gallons of gasoline in her car's tank, x.

Step-by-step explanation:

The graph of each function in the piecewise function is added as an attachment

The equation of the piecewise function is given as

f(x) = 1/4x - 5  if x < 4

In the above definition of the piecewise function, we have the following functions and the domains

f(x) = x + 3 at a domain of x ≥ 4

Note that:

The domain of the function is the set of input values of the graph

This in other words mean the domain of a function is the set of x values of the graph.

Next, we plot the graph of each function in the piecewise function in their respective domain

[tex]y=-\frac{k}{-4+k}; k \neq 4[/tex]

Step-by-step explanation:

2y + k = 6y - ky; solve for y

2y = 6y - ky - k (Subtraction Property of Equality)

2y - (6y - ky) = 6y - ky - k - (6y - ky)  (Subtraction Property of Equality)

-4y + ky = -k (Simplify)

y(-4 + k) = -k (Factor)

[tex]\frac{y(-4+k)}{-4+k}=\frac{-k}{-4+k}: k\neq 4[/tex] (Division Property of Equality)

   [tex]y=-\frac{k}{-4+k}; k \neq 4[/tex] (Simplify)

The value of y is k/ (4- k).

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific variables in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to different addition, subtraction, multiplication, and division arithmetic operations.

Given:

2y + k = 6y - ky

Now, solving for y

2y -6y + ky = -k

-4y + ky= -k

y( k-4) = -k

y = -k/(k -4)

y= k/ (4- k)

Hence, the value of y is k/ (4- k).

Given that,

The endpoints of the directed line segment QR are Q(8, 4) and R. (-2, -1).

We have to find the coordinates of the QR line segment aimed at point P along that QP to PR is a 1 to 4 ratio.

QR has the endpoints Q(8, 4) and R. (-2, -1).

Line segment QR divides at point P in ratio 1:4.

Using section formula:

The section formula provides the coordinates of a point that, either internally or externally, divides the line connecting two locations in a ratio.

P(x,y)=[tex](\frac{mx_{2} +nx_{1} }{m+n},\frac{my_{2} +ny_{1} }{m+n},)[/tex]

Where m is 1 and n is 4. x₁=8,y₁=4 and x₂=-2,y₂=-1.

Substitute in the formulae we get,

P(x,y)=((1×-1+4×8)/1+4,(1×-1+4×4/1+4))

P(x,y)=((-1+32)/5,(-1+8)/5)

P(x,y)=(31/5,7/5)

The table demonstrates that the function y = 2x + 7 and the function y = -x + 4 both have values of 5 for x = -1.

As a result, the two functions' graphs will intersect at (1, 5)

First of all, we create 2 LINEAR function, i created the function f(x)=2x+5 and the function h(x)=3x+2, both are linear(without a quadratic term). Then

Choose a group of x values before creating the table. Add each x value from the left side column to the equation. To find the y value, evaluate the equation (middle column). Since the table of values really only contains x and y pairs, you can choose to omit the middle column from your table as an optional step.

you replace the x for a number:

Table 1 (F(X)=2X+5)                                 Table 2 (H(X)=3X+2)

X=1----->Y=2+5=7                                     X=1------>Y=3·1+2=5
