Answer 1

Answer:

[tex]S_1 = 12 \\ S_2 = 54 \\ S_3 = 126 \\ S_n = 15n^2 - 3n [/tex]

Explanation:

[tex]S_1 = 12 \\ S_2 = 12 +42 = 54 \\ S_3 = 12 + 42 + 72 = 126[/tex]

To calculate for [tex]S_n[/tex], note that the series is an arithmetic series because each term is equal to the preceding term plus a constant, which is 30 (called common difference).

We let

[tex]a_1 = \text{ first term} = 12 \\ a_2 = \text{ second term} = 42 \\ a_3 = \text{ third term} = 72\\. \\. \\. \\a_n = n\text{th term}[/tex]

Since [tex]S_n[/tex] is an arithmetic series, [tex]a_1, a_2, a_3, ... , a_n[/tex] is an arithmetic sequence and so the formula for the nth term is given by

[tex]a_n = a_1 + d(n - 1) \\ a_n = 12 + 30(n - 1) \\ \boxed{a_n = 30n - 18}[/tex]

Where d = common difference = 30

Now, since [tex]S_n[/tex] is an arithmetic series, we can use the formula for the sum of the arithmetic series, which is given by

[tex]S_n = \frac{n}{2} (a_1 + a_n) \\ \\ = \frac{n}{2} (12 + 30n - 18) \\ \\= \frac{n}{2} (30n - 6) \\ \\ = \frac{30n^2 - 6n}{2} \\ \\ \boxed{S_n = 15n^2 - 3n}[/tex]

Find the least common multiple of x² + x – 12 and x² + 2x – 15.

Answers

Solution:

we have been asked to find the Least Common multiple of the given polynomial x² + x – 12 and x² + 2x – 15.

To find the least common multiple. Lets first find the factors.

[tex] x^2+x-12=x^2+4x-3x-12\\
\\
x^2+x-12=x(x+4)-3(x+4)\\
\\
x^2+x-12=(x+4)(x-3)\\ [/tex]

[tex] x^2+2x-15=x^2+5x-3x-15\\
\\
x^2+2x-15=x(x+5)-3(x+5)\\
\\
x^2+2x-15=(x+5)(x-3)\\ [/tex]

Hence the LCM of the given set of Polynomials is (x+4)(x-3)(x+5).

The LCM is (x+4)*(x-3)*(x+5)

Answers

A:

40% = 0.4

15*0.4 = 6

15 + 6 = 21

The marked up price is $21

B:

To find the discounted price:

25% = 0.25

38*0.25 = 9.5

38 - 9.50 = 28.50

To find the tax and price after tax:

6% = 0.06

28.50*0.06 = 1.71

So tax is $1.71

28.50 + 1.71 = 30.21

Price after tax is $30.21

There are

So, there are 33 +13 -6 = 40 numbers in the range 1 .. 200 that are multiples of either 6 or 15 or both.

The remaining 200 -40 = 160 numbers are not multiples of either.

In parallelogram DEFG, DH = x + 3, HF = 3y, GH = 3x – 3, and HE = 5y + 4. Find the values of x and y.
x = 5, y = 12
x = 5, y = 9
x = 4, y = 9
x = 9, y = 4

Answers

We have that in this case the following equalities are met:
DH = HF
x + 3 = 3y
GH = HE
3x - 3 = 5y + 4
We then have the following system of equations:
x-3y = -3
3x-5y = 7
Resolving the system graphically we obtain the following values:
x = 9
y = 4
Note: see attached image.
Answer:
The values of x and y are:
x = 9, y = 4

Final answer:

In parallelogram DEFG, DH = x + 3, HF = 3y, GH = 3x – 3, and HE = 5y + 4. Solving the equations yields x = 9, y = 4.

Explanation:

To find the values of x and y in parallelogram DEFG, we'll use the properties of parallelograms. In a parallelogram, opposite sides are equal in length.

Given that DH = x + 3 and HF = 3y, and that DH is opposite to HF, we have:

x + 3 = 3y ...(1)

Similarly, given GH = 3x - 3 and HE = 5y + 4, and that GH is opposite to HE, we have:

3x - 3 = 5y + 4 ...(2)

Now, we have a system of two equations (1) and (2) to solve for x and y.

From equation (1):

x = 3y - 3 ...(3)

Substitute equation (3) into equation (2):

3(3y - 3) - 3 = 5y + 4

9y - 9 - 3 = 5y + 4

9y - 12 = 5y + 4

4y = 16

y = 4

Now, substitute the value of y into equation (3):

x = 3(4) - 3

x = 12 - 3

x = 9

So, the values of x and y are x = 9 and y = 4. Thus, the correct answer is x = 9, y = 4.

B. 60 in^3
C. 188 in^3
D. 6,000 in^3

I think it's 600 and I think they made a typo but, help please.,

Answers

The volume of 100 pages of the book is 20 in³.

Explanation:
Since the book is rectangular, we use the formula for the volume of a rectangular prism: V = l*w*h.

Using the measurements of the book we have
V = 10*8*(3/4) = 80*(3/4) = 240/4 = 60 in³.

However, 100 out of 300 pages means we want 100/300 = 1/3 of the book: 60(1/3) = 60/3 = 20 in³.

Answer:

A. [tex]20\text{ in}^3[/tex]

Step-by-step explanation:

We have been given that a 300-page book is 10 inches long, 8 inches wide, and 3/4 inches tall. We are asked to find the volume of 100 pages of the book.

First of all, we will find the volume of whole book using volume of cuboid formula.

[tex]\text{Volume of cuboid}=l\cdot w\cdot h[/tex], where,

l = Length of cuboid,

w = Width of cuboid,

h = Height of cuboid.

Upon substituting our given values in volume formula we will get,

[tex]\text{Volume of entire book}=10\text{ in}\times 8\text{ in}\times \frac{3}{4}\text{ in}[/tex]

[tex]\text{Volume of entire book}=10\text{ in}\times 2\text{ in}\times 3\text{ in}[/tex]

[tex]\text{Volume of entire book}=60\text{ in}^3[/tex]

Since there are 300 pages in entire book and 100 is 1/3 of 300, so the volume of 100 pages will be the 1/3 of the volume of entire book.

[tex]\text{Volume of 100 pages}=\frac{60\text{ in}^3}{3}[/tex]

[tex]\text{Volume of 100 pages}=20\text{ in}^3[/tex]

Therefore, the volume of 100 pages will be 20 cubic inches and option A is the correct choice.

A tent forms an equilateral triangular prism, with both triangular faces exposed. each side of the triangular face has a length of 196196196 centimeters (\text{cm})(cm)left parenthesis, c, m, right parenthesis, and the tent is 250\,\text{cm}250cm250, space, c, m long. what is the height, in centimeters, of the tent?

Answers

Given:
Equilateral Triangular Prism
Each side of the triangular face has a length of 196cm
The tent is 250cm long

I have attached an image of the tent. Since the height of the tent is also the height of the triangle, I will solve for the height of the triangle using Pythagorean theorem.

I divided the equilateral triangle into 2 right triangle. The height then becomes the long leg of the triangle. The hypotenuse is 196cm and the short leg is 98cm, half of one side of the triangle.

a² + b² = c²
a² = c² - b²
a² = (196cm)² - (98cm)²
a² = 38,416cm² - 9,604cm²
a² = 28,812cm²
a = √28,812cm²
a = 169.74cm

The height of the tent is 169.74 centimeters.

A trapezoid has an area of 150 square meters. If the bases are 14 meters and 16 meters, what us the height of the trapezoid?

Answers

To find the area of a trapezoid, we use the following formula:
[tex]a = \frac{1}{2} (b1 + b2) \times h[/tex]
In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.

So, we have got the following information
[tex]a = 150[/tex]
[tex]b1 = 14[/tex]
[tex]b2 = 16[/tex]

Filling in the formula gives us:
[tex]150 = \frac{{1} }{2} \times (14 + 16) \times h[/tex]
[tex]150 = \frac{1}{2} \times 30 \times h[/tex]
[tex]150 = 15 \times h[/tex]
Finally we have to divide both sides by 15.
[tex]h = 150 \div 15 = 10[/tex]
Therefore, the height of the trapezoid is 10 meters.

You could also input the x values and see which equation produces the y values in the chart.

On thing to notice is the we have negative output values, there we need to pick either B or D, so the values go beneath the x-axis.

Answer:

option D.

Step-by-step explanation:

Data given in the table is

x 2 3 4

f(x) -3 0 12

Now we will plug in the values of x in the given functions to find the correct exponential function.

For x =2

A). f(x) = 4(4)[tex]^{(x-1)}[/tex] + 4

f(2) = 4(4)[tex]^{2-1}[/tex] + 4 = 4 × 4 + 4 = 20

B). f(x) = 4(4)[tex]^{(2-1)}[/tex] - 4

f(2) = 4(4)[tex]^{2-1}[/tex] - 4 = (4)(4) - 4 = 16 - 4 = 12

C). f(x) = 1/4(4)[tex]^{x-1}[/tex] +4

1/4(4)[tex]^{2-1}[/tex] + 4 = [tex]\frac{1}{4}[/tex] × 4 + 4

= 1 + 4 = 5

D). f(x) = [tex]\frac{1}{4}(4)^{x-1}-4[/tex]

f(2) = [tex]\frac{1}{4} (4)^{2-1}-4=\frac{1}{4}(4)-4[/tex]

= 1 - 4 = -3

We find option D in which f(2) = (-3). so the answer would be option D.

I want to verify my answers:
Discontinuous for the car
Continuous for the students,

Answers

Continuous functions of time are a function if small changes are made to the source then the result will have those small changes in them. The quantity of gas is a continuous function of time because small variations can be made to the quantity of the gas in use to the extent of molecules and atoms whereas same cannot be done to the student as we cannot half them.

Final answer:

The quantity of gas in a car's tank during a journey is continuous, whereas the number of students enrolled in a class is discontinuous due to discrete changes.

Explanation:

Continuous functions of time imply that values can change smoothly without jumps or breaks. For the quantity of gas in the tank of a car on a journey between New York and Boston, this would be a continuous function because the gas level decreases gradually as the car is driven. However, for the number of students enrolled in a class during a semester, this is a discontinuous function, because the enrollment can only change through discrete additions or subtractions when students enroll or drop out of the class.

Also, note:
________________________________________________

x² = 32 ; Solve for "x" ;

→ Take the square root of "each side" of the equation ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ √(x²) = √32 ;

→ | x | = √32 ;

→ x = ± √32 . Yes!

Which of the following describes the transformations of g(x)=-(2)x+4-2 from the parent function f(x)=2x

Answers

This graph has a few changes. It is reflected across the axis, then shifted left 4 units. it is also shifted down two units.

Answer:

function f(x) first reflect across x axis and then shifted 4 unit up and then 2 unit down.

Step-by-step explanation:

Given : Transformations of g(x)=-(2)x+4-2 from the parent function f(x)=2x.

To find : Which of the following describes the transformations.

Solution : We have given

Parent function f(x) = 2x.

Transformed function g(x) = -(2)x+4-2.

By the transformation rule : (1) reflection across x - axis f(x) →→ -f(x) .

(2) f(x) →→ f(x) + k it mean function shifted up by k unit.

(3) f(x) →→ f(x) - k it mean function shifted down by k unit.

Then

f(x) = 2x →→→→-(2)x+4-2.

It mean function f(x) first reflect across x axis and then shifted 4 unit up and then 2 unit down.

Therefore, function f(x) first reflect across x axis and then shifted 4 unit up and then 2 unit down.
