11) Write the explicit formula
for the sequence below and
use it to find the 47th term:
-3, 5, 13, 21,...

Answer:

y = 3/2x + 5

Step-by-step explanation:

2y - 3x - 10 = 0

2y = 3x + 10

y = 3/2x + 5

Answer:

n = -3

Step-by-step explanation:

11(n – 1) + 35 = 3n

Distribute

11n -11 +35 = 3n

Combine like terms

11n +24 = 3n

Subtract 11n from each side

11n+24 -11n = 3n -11n

24 = -8n

Divide by -8

24/-8 = -8n=-8

-3 =n

Answer: HI your question is incomplete/poorly attached below is the complete question

answer

( a + 3 ) , ( b + 2 )

Step-by-step explanation:

Given expression = ab + 2a + 3b + 6  

factorizing the expression completely we will have

  = a( b + 2 ) + 3 ( b + 2 )

hence the factors of the expression = ( a + 3 ) , ( b + 2 )

Answer:

To create function h, function f was translated 2 units right , translated 4 units up and reflected across the x axis

Step-by-step explanation:

Given

[tex]f(x) = x^3[/tex]

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

Required

Complete chart

First: f(x) was translated right by 2 units

The rule of right translation is [tex](x,y) \to (x + 2,y)[/tex]

So, we have:

[tex]f'(x) = f(x + 2)[/tex]

[tex]f'(x) = (x + 2)^3[/tex]

Next: f'(x) was translated up by 4 units

The rule of down translation is [tex](x,y) \to (x,y+4)[/tex]

So, we have:

[tex]f"(x) = f'(x) +4[/tex]

[tex]f"(x) = (x + 2)^3 +4[/tex]

Lastly, f"(x) was reflected across the x-axis;

The rule of this reflection is: [tex](x,y) \to (x,-y)[/tex]

So, we have:

[tex]h(x) = -f"(x)[/tex]

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

Remove bracket

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

Answer:

[tex]Pr = \frac{1}{45}[/tex]

Step-by-step explanation:

Given

[tex]Black =5[/tex]

[tex]Pink = 2[/tex]

[tex]Blue = 3[/tex]

Required

[tex]P(Pink\ and\ Pink)[/tex]

This is calculated as:

[tex]Pr = P(Pink) * P(Pink)[/tex]

Because it is a selection without replacement, the probability is:

[tex]Pr = \frac{n(Pink)}{Total} * \frac{n(Pink) - 1}{Total - 1}[/tex]

[tex]Pr = \frac{2}{10} * \frac{2 - 1}{10 - 1}[/tex]

[tex]Pr = \frac{2}{10} * \frac{1}{9}[/tex]

[tex]Pr = \frac{1}{5} * \frac{1}{9}[/tex]

[tex]Pr = \frac{1}{45}[/tex]

Answer:

A = 301.593 ft^2

Step-by-step explanation:

The lateral area of a cylinder of radius r and height h is

A = 2πrh.  This does not include the areas of the ends of the cylinder.

Here that area is A = 2(3.14159)(6 ft)(8 ft), or

                             A = 301.593 ft^2

Answer:

Not a solution

Step-by-step explanation:

In order for [tex]x=-2[/tex] to be a solution, the result after substituting must be 0:

[tex]4(-2)^3-(-2)^2+16(-2)-4\stackrel{?}{=}0[/tex]

[tex]4(-8)-4-32-4\stackrel{?}{=}0[/tex]

[tex]-32-40\stackrel{?}{=}0[/tex]

[tex]-72\neq0[/tex]

Therefore, [tex]x=-2[/tex] is not a solution to [tex]4x^3-x^2+16x-4[/tex]

Answer:

Use SOHCAHTOA

Step-by-step explanation:

If you don't know what this is, it means Sin=opposite/hypotenuse, cos=adjacent/hypotenuse, tan=opposite/adjacent. There is more than 1 way to solve this, but here's how I did it.

Starting with part A, we are trying to find the hypotenuse of the triangle. We have an angle and the side opposite of that angle, so we can use the sin function.

Sin(54) = 12.2 / hypotenuse

Sin(54) * hypotenuse = 12.2

Hypotenuse = 12.2 / sin(54) = 15.1

Now for Part B

Finding the last angle

180-90-54=36

So now, we have this angle and the side adjacent to it. We are trying to find the opposite side, so let's use the tan function

Tan(36) = opp / 12.2

opp = tan(36) * 12.2 = 8.9

You can double check these answers using pythagorean theorem. Hope this helps

Answer:

16x+24y

Step-by-step explanation:

8(2x+3y)

8*2x+8*3y

16x+24y

Answer:

a= 18x

Step-by-step explanation:

(a+d)/2 = 10x   (1)

(b +c)/2 = 8x  (2)

(b+c+d)/3 = 6x (3)

From the equation 2, we have (b+c)= 8x *2 = 16x

From the equation 3, we have d= 6x*3 - (b+c)= 18x- 16x = 2x

From the equation 1, we have a= 10x*2 -d= 20x - 2x= 18x

Answer:

The question is incomplete. The complete question is :

A survey was done to determine the relationship between gender and subject preference. A total of  56 students were surveyed to determine if they liked math, English, social studies, or science as their  favorite subject. The results were then broken down based on whether the respondent was male or  female.

Which of the following is the closest to the joint relative frequency of being a male who likes social studies ?

Solution :

A two way table used in statistics and mathematics is used to show the frequencies or the relative frequencies for any two categorical variables.  One of the category is represented by the rows while the other categories by a column.

Here, in this table it is given that the total surveyed = 56 students

From the table, we know that number of males who likes social studies = 8

Therefore, the closest to the joint relative frequency for being a male who likes the subject social studies is given by :

[tex]$=\frac{8}{56}$[/tex]

[tex]$=\frac{1}{7}$[/tex]

Answer:

Height = 5 and Base = 10

Step-by-step explanation:

The base of the parallelogram is twice the perpendicular height of the parallelogram. The area of the parallelogram is 50 cm².

Formula for area of parallelogram = base × height

Base = 2h

Height = h

∴ Area = 2h × h = 50

Solution:

2h × h = 50

2h² = 50

[tex]\frac{2h^{2} }{2} = \frac{50}{2}[/tex]

h² = 25

[tex]\sqrt{h^{2} } = \sqrt{25}[/tex]

h = 5

∴ height = 5 and base = 2(5) = 10

Answer:

(1,4)

Step-by-step explanation:

Hi there!

We're given the system:

y=3x+1

y=x+3

We need to find the common solution (the point at which the lines intersect); we do this by finding the value of the variables.

Let's start with x

Since both equations equal y, we can make 3x+1 and x+3 equal to each other, because of a property known as transitivity (if a=b and b=c, then a=c)

3x+1=x+3

subtract 1 from both sides

3x=x+2

subtract x from both sides

2x=2

divide both sides by 2

x=1

we found the value of x

now we need to find the value of y

We do this by plugging x as 1 into either one of the equations to solve for y

let's use y=x+3 for example

substitute x as 1

y=1+3

add

y=4

we found the value of y.

Your question asks for the answer to be written as an ordered pair, which will be (1,4)

Hope this helps!

Answer:

(1, 4 )

Step-by-step explanation:

Given the 2 equations

y = 3x + 1 → (1)

y = x + 3 → (2)

Substitute y = 3x + 1 into (2)

3x + 1 = x + 3 ( subtract x from both sides )

2x + 1 = 3 ( subtract 1 from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (2)

y = 1 + 3 = 4

solution is (1, 4 )
