Help solve this I’m not sure if my answer was right. Pythagorean theorem.

Answer:

see explanation

Step-by-step explanation:

Substitute n = 7 into f(n)

f(7) = 5 + 8(7 - 1) = 5 + 8(6) = 5 + 48 = 53

f(n) = 5 + 8(n - 1) represents the nth term of an arithmetic sequence

f(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

By comparison, then

a₁ = 5 and common difference d = 8

Answer:

Cost function = 40a + 500

Cost of 90 articles = $4,100

Step-by-step explanation:

The fixed cost is $500 and it will.not change regardless of production level.

The Variable cost is $40 and increases by every additional unit produced.

Assume the number of articles produced is a.

Cost function would be:

Total cost = Variable cost * Number of articles + Fixed cost

TC = 40a + 500

Using this, the cost of 90 articles is:

= 40 * 90 + 500

= $4,100

Answer: (5a+1) (a+1)

-20

Explanation:

( − 7   ^ 2  −  4 )  +  ( − 7   ^ 2  −  6  − 2 )

Eliminate the redundant parentheses, subtract the numbers which will get you, combine like terms, rearrange terms, then your solution is:

− 1 4 2 −6 −6

Figure that problem out then you will get -20.

Answer:

−14x^2 − 6x - 6

Step-by-step explanation:

(−7x 2 −4)+(−7x 2 −6x−2) should be written as (−7x^2 −4) + (−7x^2 −6x−2).  The " ^ " symbol denotes exponentiation.  7x^2 means "7 times the square of x."  We can immediately remove the parentheses, obtaining:

−7x^2 −4 −7x^2 − 6x − 2

Our next step is to combine like terms.  For example, -7x^2 appears twice, with the same (negative) sign; summing these up results in -14x^2.

Immediately after doing that, we have:

−14x^2 −4 − 6x − 2

and need to combine the constants -4 and -2:

−14x^2 −6 − 6x

Finally, we write these terms in descending powers of x:

−14x^2 − 6x - 6

Answer:

A function is a relation that maps elements from one set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs). Such that each element of the domain can be mapped into only one element of the range.

Now let's analyze the given relations.

1)

Here we can see that the inputs are -3, -1, 1, and 2.

Then the domain (the set of the inputs) is:

D = {-3, -1, 1, 2}

And we can see that the outputs are 0, 2, and 5.

Then the range is:

R = {0, 2, 5}

We also can see that each input is being mapped into only one output, then this relation is a function.

2) In this case the inputs are -2, -3, and 5.

Then the domain is:

D = {-2, -3, 5}

And the outputs are 6, 7, 8

Then the range is:

R = {6, 7, 8}

And we can see that each input is mapped into only one output, then this relation is a function.

3) In this case we can see that the inputs are -4, -2, and 0

Then the domain is:

D = {-4, -2, 0}

And we can see that the outputs are -2, -1, 3, and 4.

Then the range is:

R = {-2, -1, 3, 4}

In this case, we can see that the input -4 is being mapped into two different outputs (3 and -1)

Then this relation is not a function.

Answer:

x=33

Step-by-step explanation:

1) write the equation: 180=90+(x+15)+(x+9)

2) subtract 90 on both sides and add x+15 and x+9 together: 90=2x+24

3) subtract 24 from both sides: 66=2x

4) divide both sides by 2: x=33

Answer:

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

=

9

7

= 1.2857142857143

θ =

arctan( ΔY )

ΔX

= 52.125016348902°

ΔX = 49 – 21 = 28

ΔY = 63 – 27 = 36

Distance (d) = √ΔX2 + ΔY2 = √2080 = 45.607017003966

Equation of the line:

y = 1.2857142857143x – 3.5527136788005E-15

When x=0, y = -3.5527136788005E-15

When y=0, x = 2.7632217501782E-15

If 1 Point and the Slope are Known:0.75

Answer:

y=(-7/2)x+3

Step-by-step explanation:

7x+2y-3=0

7x+2y=3

2y=-7x+3

y=(-7/2)x+3

Answer:

y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

7x + 2y - 3 = 0 ( subtract 7x - 3 from both sides )

2y = - 7x + 3 ( divide each term by 2 )

y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← in slope- intercept form

Answer:

price for one shirt

=

$

7.50

price for one pair of pants

=

$

18.50

Explanation:

Start by letting variables

x

and

y

represent the pieces of clothing from the problem.

Let

x

be the price of one shirt.

Let

y

be the price of one pair of pants.

Equation

1

:

4

x

+

3

y

=

85.50

Equation

2

:

3

x

+

5

y

=

115.00

You can solve for each variable by using elimination or substitution. However, in this case, we will use use elimination. First, we will solve for

y

, the price of each pair of pants.

To isolate for

y

, we must eliminate

x

. We can do this by making the two equations have the same

x

values. First, we find the LCM of

4

and

3

, which is

12

. Next, multiply equation

1

by

3

and equation

2

by

4

so that

4

x

and

3

x

becomes

12

x

in both equations.

Equation

1

:

4

x

+

3

y

=

85.50

3

(

4

x

+

3

y

)

=

3

(

85.50

)

12

x

+

9

y

=

256.50

Equation

2

:

3

x

+

5

y

=

115.00

4

(

3

x

+

5

y

)

=

4

(

115.00

)

12

x

+

20

y

=

460.00

Now that we have two equations with

12

x

, we can subtract equation

2

from equation

1

to solve for

y

.

12

x

+

9

y

=

256.50

12

x

+

20

y

=

460.00

−

11

y

=

−

203.50

y

=

18.50

⇒

price for one pair of pants

Now that we know that a pair of pants is

$

18.50

, we can substitute this value into either equation

1

or

2

to find price for one shirt. In this case, we will choose equation

1

.

4

x

+

3

y

=

85.50

4

x

+

3

(

18.50

)

=

85.50

4

x

+

55.5

=

85.50

4

x

=

28

x

=

7.50

⇒

price for one shirt

∴

, the price for one shirt is

$

7.50

and the price for one pair of pants is

$

18.50

.

Answer:

(a)

[tex]S = \{GGG, GGB, GBG, GBB, BBG, BGB, BGG, BBB\}[/tex]

(b)

i.

[tex]1\ girl = \{GBB, BBG, BGB\}[/tex]

[tex]P(1\ girl) = 0.375[/tex]

ii.

[tex]Atleast\ 2 \ girls = \{GGG, GGB, GBG, BGG\}[/tex]

[tex]P(Atleast\ 2 \ girls) = 0.5[/tex]

iii.

[tex]No\ girl = \{BBB\}[/tex]

[tex]P(No\ girl) = 0.125[/tex]

Step-by-step explanation:

Given

[tex]Children = 3[/tex]

[tex]B = Boys[/tex]

[tex]G = Girls[/tex]

Solving (a): List all possible elements using set-roster notation.

The possible elements are:

[tex]S = \{GGG, GGB, GBG, GBB, BBG, BGB, BGG, BBB\}[/tex]

And the number of elements are:

[tex]n(S) = 8[/tex]

Solving (bi) Exactly 1 girl

From the list of possible elements, we have:

[tex]1\ girl = \{GBB, BBG, BGB\}[/tex]

And the number of the list is;

[tex]n(1\ girl) = 3[/tex]

The probability is calculated as;

[tex]P(1\ girl) = \frac{n(1\ girl)}{n(S)}[/tex]

[tex]P(1\ girl) = \frac{3}{8}[/tex]

[tex]P(1\ girl) = 0.375[/tex]

Solving (bi) At least 2 are girls

From the list of possible elements, we have:

[tex]Atleast\ 2 \ girls = \{GGG, GGB, GBG, BGG\}[/tex]

And the number of the list is;

[tex]n(Atleast\ 2 \ girls) = 4[/tex]

The probability is calculated as;

[tex]P(Atleast\ 2 \ girls) = \frac{n(Atleast\ 2 \ girls)}{n(S)}[/tex]

[tex]P(Atleast\ 2 \ girls) = \frac{4}{8}[/tex]

[tex]P(Atleast\ 2 \ girls) = 0.5[/tex]

Solving (biii) No girl

From the list of possible elements, we have:

[tex]No\ girl = \{BBB\}[/tex]

And the number of the list is;

[tex]n(No\ girl) = 1[/tex]

The probability is calculated as;

[tex]P(No\ girl) = \frac{n(No\ girl)}{n(S)}[/tex]

[tex]P(No\ girl) = \frac{1}{8}[/tex]

[tex]P(No\ girl) = 0.125[/tex]
