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

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:

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

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%.

A submarine descends to a depth of 600 feet below the surface in 10 minutes. At this rate, what integer represents the change, in feet, of the submarine's position after one minute?

First you need to list what you're given.

A submarine descends to a depth of 600 ft below the surface in 10 minutes. The question is asking for the change of the submarine's position after one minute. This can be represented as fractions in terms of [tex]\frac{distance}{time}[/tex].

[tex]\frac{600}{10} = \frac{x}{1}[/tex]

You're looking for the value of x. First you need to cross-multiply.

[tex]600 \times 1 = 10 \times x\\600=10x[/tex]

Since you're looking for x alone, you need to divide both sides by 10. This will eliminate the 10 since x is being multiplied by 10, and 10 divided by 10 is 1, making it 1x or x.

[tex]\frac{600}{10} = \frac{10x}{10}[/tex]

[tex]60=x[/tex]

That means the submarine is descending at a rate of 60 feet per minute, which can be represented as -60.

If you're looking for the submarine's position after one minute, all you have to do is subtract 60.

600 feet below surface is represented as -600.

[tex]-600-60=-660[/tex]

The submarine's position after one minute is 660 feet below surface(-660).
