Answer:

-53, f(n) = -6(n-1) + 13

Step-by-step explanation:

given the equation to this linear/arithmetic sequence for the nth term: f(n) = -6(n-1) + 13

f(12) = -6(12-1) + 13

f(12) = -6(11) + 13

f(12) = -66 + 13

f(12) = -53

*substitute and simplify*

______________

f(n) = f(1) + d(n-1)

given f(1) = 13, f(2) = 7, and f(3) = 1

7-13 = 1-7 = -6 = d

= f(1) + d(n-1)

f(1) = 13 so

the equation must be f(n) = 13 - 6(n-1) or -6(n-1) + 13

Answer:

y = -1/4x - 1

Step-by-step explanation:

First, put the equation in slope intercept form:

4x - y = 2

4x - 2 - y = 0

4x - 2 = y

y = 4x - 2

Perpendicular lines have opposite reciprocal slopes. Since the original slope is 4, the other line's slope will be -1/4

Plug in the given point and the slope into y = mx + b, then solve for b:

y = mx + b

-2 = -1/4(4) + b

-2 = -1 + b

-1 = b

Plug in the slope and b into the equation:

y = -1/4x - 1 is the equation

Answer:

if a polynomial of lowest degree p has zeros at x=x1,x2,…,xn x = x 1 , x 2 , … , x n , then the polynomial can be written in the factored form: f(x)=a(x−x1)p1(x−x2)p2⋯(x−xn)pn f ( x ) = a ( x − x 1 ) p 1 ( x − x 2 ) p 2 ⋯ ( x − x n ) p n where the powers pi on each factor can be determined by the behavior of the graph ...

Answer:

Step-by-step explanation:

It is convenient to let a variable represent the number of the highest-price tickets sold. We'll use x for that. Then the number of lower-price tickets sold is 525 -x and the total revenue is ...

  8x +6(525 -x) = 4600

  2x = 1450 . . . . . . . . . . . . subtract 3150

  x = 725

  525 -x = -200

__

The school sold 725 freshman/sophomore tickets and -200 junior/senior tickets.

_____

Comment on the question

There is apparently an error in the question somewhere. The average revenue per ticket is ...

  $4600/525 ≈ $8.76

You cannot sell $6 and $8 tickets and earn more than $8 per ticket sold. (Average revenue must be between $6 and $8 per ticket.)

__

If we assume a typo in revenue, and that it should be $3600, then the sales will be 225 freshman tickets and 300 senior tickets.

Answer:

1. r1 || r2 because of the same side or consecutive interior theorem

2. l1 || l2 because they are corresponding angles

The angle formed between two parallel lines having a common transversal have several common properties

The correct responses are;

1.  Lines r₁ and r₂ are parallel

2. Lines, l₁ and l₂ are parallel

lines r₁ and r₂, are parallel

The reason why the given lines are parallel are as follows:

1. The given figures are presented as shown in the attached diagram

From the diagram, we have that the same side interior angles formed by the common transversal l₂ the lines r₁ and r₂ are 63° and 117°, which are supplementary angles (63° + 117° = 180°)

Therefore, lines r₁ and r₂ are parallel given that same side interior angles formed by two parallel lines having the same transversal are supplementary

2. From the attached diagram, we have;

The alternate exterior angles formed between the lines, l₁ and l₂ that have the common transversal r₁ are equal, therefore;

Lines, l₁ and l₂ are parallel, given that the alternate exterior angles formed by two parallel lines having a common transversal are equal

From the diagram, we also have that the other angle of the linear pair angle with the 63° angle is 117°, and the second angle of the linear pair angle is both either corresponding angle and alternate interior angle with the given 117°

Therefore, lines r₁ and r₂, are parallel given that corresponding angles and the alternate interior angles formed between parallel lines having a common transversal are equal

The equation that represents the total amount will be y = 25x + 50.

A connection between two or more factors results in a linear model when displayed on a graph. The parameter will have a degree of one.

The linear equation is given as,

y = mx + c

Where c is the line's y-intercept and m is the line's y-slope.

A photo studio charges a $50 sitting fee and $25 per photo sheet purchased.

Let x be the number of photo sheets purchased and y be the total amount.

The slope of the equation is 25 and the y-intercept will be 50.

y = 25x + 50

The equation that represents the total amount will be y = 25x + 50.

The value of cos(tan^-1(0)) is 1. Therefore, option C is the correct answer.

We need to find the value of cos(tan^-1(0)).

In mathematics, trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Now, cos(tan^-1(0))

⇒tan^-1(0)=0

⇒cos(0)=1

The value of cos(tan^-1(0)) is 1. Therefore, option C is the correct answer.

Answer:

The answer is 4.

Step-by-step explanation:

The total percent is 100%. You subtract 100% with 72% which is 28. Then, you divide 28 with 7 and voila! The answer is 4.

The change in  her score in percentage points for each question she gets incorrect is 4%.

Using this formula

Change in score percentage=(100%-Scores %)/Number of missed questions

Where:

Scores %=72%

Number of missed questions=7 questions

Let plug in the formula

Change in score percentage=(100%-72%)/7

Change in score percentage=28%/7

Change in score percentage=4%

Inconclusion  the change in  her score in percentage points for each question she gets incorrect is 4%.
