What are the domain and range of the absolute value parent function?

Answer:

3 is the correct option.

Step-by-step explanation:

The given expression is:

3k+6/(k-2)+(2-k)

Break the numerators:

3k/(k-2) + 6/(2-k)

Now Re-arrange the term (2-k) in the denominator as (-k+2)

3k/(k-2) + 6/(-k+2)

Now takeout -1 as a common factor from (-k+2)

3k/(k-2) + 6/-1(k-2)

Now  move a negative (-1)from the denominator of 6/-1(k-2) to the numerator

3k/(k-2) + -1*6/(k-2)

Now take the L.C.M of the denominator which is k-2 and solve the numerator

3k - 6/ (k-2)

Take 3 as a common factor from the numerator:

3(k-2)/(k-2)

k-2 will be cancelled out by each other:

Thus the answer will be 3.

The correct option is 3....

Answer:

x² + y² = 36

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ← r is the radius

here r = 6, so

x² + y² = 6², that is

x² + y² = 36

The circle's equation is x² + y² = 36.

Given:

length of its radius is 6.

To find:

the circle's equation

The equation for a circle in center, radius form is

(x - h)² + (y - k)² = r²  

The equation of a circle centered at the origin is

x² + y² = r²  

Where, r is the radius of the circle

Here radius of the circle = 6

If the center is (0,0) then h = 0 and k = 0

x² + y² = 6²,

x² + y² = 36

Therefore, the circle's equation x² + y² = 36.

Answer:

[tex]a_n=9.5 \cdot (0.2)^{n-1}[/tex]

Step-by-step explanation:

If this is a geometric sequence, it will have a common ratio.

The common ratio can be found by dividing term by previous term.

The explicit form for a geometric sequence is [tex]a_n=a_1 \cdot r^{n-1} \text{ where } a_1 \text{ is the first term and } r \text{ is the common ratio}[/tex]

We are have the first term is [tex]a_1=9.5[/tex].

Now let's see this is indeed a geometric sequence.

Is 0.076/0.38=0.38/1.9=1.9/9.5?

Typing each fraction into calculator and see if you get the same number.

Each fraction equal 0.2 so the common ratio is 0.2.

So the explicit form for our sequence is

[tex]a_n=9.5 \cdot (0.2)^{n-1}[/tex]

Final answer:

A geometric sequence follows a specific pattern where each term is obtained by multiplying the previous term by a constant ratio. The explicit rule for a geometric sequence is defined by the first term, the term number, and the common ratio.

Explanation:

Geometric series are sequences in which each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. The explicit rule for a geometric sequence is of the form an = a₁ * r⁽ⁿ⁻¹⁾, where a₁ is the first term, n is the term number, and r is the common ratio.

Answer:

a) P(z>1.16) = 0.8770

b) P(z>-0.75) = 0.2266

Step-by-step explanation:

Mean = 205 cm

Standard Deviation = 8.6 cm

a) Find the probability that an individual distance is greater than 215.00

We need to find P(X>215)

x = 215

z = x - mean /standard deviation

z = 215 - 205 / 8.6

z = 1.16

P(X>215)=P(z>1.16)

Finding value of z =1.16 from the table

P(z>1.16) = 0.8770

b) Find the probability that the mean for 25 randomly selected distances is greater than 203.70 cm

Sample size n= 25

x = 203.70

mean = x- mean / standard deviation / √sample size

mean = 203.70 - 205 / 8.6 / √25

mean = -1.3/8.6/5

mean = -0.75

Finding value from z-score table

P(mean >-0.75) = 0.2266

c) Why can the normal distribution be used in part​ (b), even though the sample size does not exceed​ 30?

If the original problem is normally distributed, then for any sample size n, the sample means are normally distributed.

Answer:

The other two vertices are (4 , -2) and (4 , 2) ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- All the points on a vertical line have thee same x-coordinates

- In the vertical segment whose endpoints are (x , y1) and (x , y2)

 its length = y2 - y1

- All the points on a horizontal line have thee same y-coordinates

- In the horizontal segment whose endpoints are (x1 , y) and (x2 , y)

 its length = x2 - x1

* Lets solve the problem

- The two vertices of the garden are (-1 , 2) , (-1 , -2)

- The side joining the two vertices is vertical because the points have

  the same x-coordinate

∴ The length of the height = 2 - -2 = 2 + 2 = 4

∴ The length of the height of the garden is 4 feet

∵ The garden shaped a rectangle

∵ The area of the garden is 20 feet²

- The area of the rectangle = base × height

∵ The height = 4 feet

∴ 20 = base × 4 ⇒ divide both sides by 4

∴ Base = 5 feet

∴ The length of the base of the garden is 5 feet

- The adjacent side to the height of the rectangle is horizontal line

∵ The points on the horizontal line have the same y-coordinates

∴ The adjacent vertex to vertex (-1 , 2) has the same y-coordinates 2

∵ The length of the horizontal segment is x2 - x1

∴ 5 = x - (-1)

∴ 5 = x + 1 ⇒ subtract 1 from both sides

∴ x = 4

∴ The adjacent vertex to (-1 , 2) is (4 , 2)

- Lets find the other vertex by the same way

∵ The adjacent vertex to vertex (-1 , -2) has the same y-coordinates -2

∵ x-coordinate of this vertex is the same with x- coordinate of point

 (4 , 2) because these two points formed vertical side

∴ The other vertex is (4 , -2)

∴ The adjacent vertex to (-1 , -2) is (4 , -2)

* The other two vertices are (4 , -2) and (4 , 2)

Step-by-step explanation:

Answer:

The smaller angle= 68°

The larger angle=112°

Step-by-step explanation:

Supplementary angles add up to 180°

Let the smaller of the angles to x then the larger angle will be x+44.

Adding the two then equating to 180°:

x+(x+44)=180

2x+44=180

2x=180-44

2x=136

x=68

The smaller angle= 68°

The larger angle=68+44=112°

Answer:

The angles are 68° , 112°

Step-by-step explanation:

Let the smaller angle be x

so the larger angle = x + 44

x , x + 44 are supplementary.

so,    x  + (x + 44) = 180

         x  + x + 44  = 180

                      2x  = 180 - 44 = 136

                          x = 136/2 = 68    

 the larger angle = x + 44 = 68 + 44 = 112

Answer:

y=x-4

Step-by-step explanation:

What you are looking for is also known as the slant asymptote.  The slant asymptote occurs when the degree of the numerator is one degree more than the denominator which is what you have.

So to find the slant asymptote we can use polynomial division.

We have a choice to use synthetic division here because the denominator is linear.

-1 goes on the outside because we are dividing by (x+1).

-1  |    1     -3      -4

   |           -1        4

   |----------------------

        1      -4        0

The asymptote is the quotient part which is y=x-4.

So answer is y=x-4.

Option D is correct, y=x-4​ is the equation of the oblique asymptote h(x)= x²-3x-4/x+1

Two or more expressions with an Equal sign is called as Equation.

To find the equation of the oblique asymptote, we need to perform polynomial division of the numerator (x² - 3x - 4) by the denominator (x + 1):

       x - 4

    ------------

x + 1 | x² - 3x - 4

        x² + x

      -------

          -4x - 4

          -4x - 4

             -------

               0

The quotient is x - 4, which represents the equation of the slant asymptote.

Hence, y=x-4​ is the equation of the oblique asymptote h(x)= x²-3x-4/x+1

Answer:

62.8

Step-by-step explanation:

The volume of the cylinder is = base * height

base=Pi*radius*radius, where

base=3.1416*2*2 , height=5

Volume=3.1416*2*2*5

Volume =62.8 cubic units.

Answer:

Option B.

Step-by-step explanation:

It is given that right cylinder has a radius of 2 units and a height of 5 units. It means

r = 2

h = 5

The volume of a right cylinder is

[tex]V=\pi r^2h[/tex]

where, r is radius and h is height of the cylinder.

Substitute r=2 and h=5 in the above formula.

[tex]V=\pi (2)^2(5)[/tex]

[tex]V=\pi (4)(5)[/tex]

[tex]V=20\pi[/tex]

On further simplification we get

[tex]V=62.831853[/tex]

[tex]V\approx 62.8[/tex]

The volume of right cylinder is 62.8 cubic units.

Therefore, the correct option is B.

Subtract 1 on both sides. [tex]2x=1106[/tex]

Divide both sides by 2. [tex]x=553[/tex]

The first number is [tex]x[/tex], which equals [tex]\boxed{553}[/tex].

The second number is [tex]x+1[/tex], which equals [tex]553+1[/tex], which is [tex]\boxed{554}[/tex].

These numbers can be presented as n and n + 1 = 1107

2n = 1106 because we combine the n terms and subtract 1 from each side.

2n ÷ 2 = n

1106 ÷ 2 = 553

We now know that n = 553.

Our second consecutive integer must be 554. This is because our second

consecutive integer represents n + 1 so 553 + 1 =554.

Therefore, are two consecutive integers are 553 and 554.

Step-by-step explanation:

Given:

r= 14.5

AB cuts r=14.5 in two parts one parts length=4

remaining length, x = 14.5 - 4 =10.5

draw a line from center of circle to point A making right angled triangle

Now hypotenuse=r=14.5

and one side of triangle=10.5

Using pythagoras theorem to find the third side:

c^2=a^2+b^2

14.5^2=10.5^2+b^2

14.5^2-10.5^2=b^2

b^2=100

b=10

AB=2b

B if m=2

(Just to make sure that isn't m=-2, right?)

Step-by-step explanation:

7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)  

Let's plug in 2 for m.

7.8+2(0.75*2+0.4)  = -6.4*2+4(0.5*2-0.8)

If 2 is a solution, then both sides will be the same.

If 2 is not a solution, then both sides will be different.

If both sides are the same, it is a true equation.

If both sides are different, it is a false equation.

Let's simplify 7.8+2(0.75*2+0.4)

According to PEMDAS, we must perform the operations in the parenthesis.

We have multiplication and addition in ( ).  We will do the multiplication because the MD comes before the AS.

0.75*2=1.5

So now our expression 7.8+2(0.75*2+0.4) becomes 7.8+2(1.5+0.4)

Now to do the addition in the ( ).

1.5+0.4=1.9.

So now our expression 7.8+2(0.75*2+0.4) becomes 7.8+2(1.9).

We have multiplication to be perform now because again MD becomes before AS.

7.8+2(0.75*2+0.4) becomes 7.8+3.8

Last step perform the addition (the only operation left here on the left hand side)

7.8+2(0.75*2+0.4) becomes 11.6 .

Let's focus on the right now.

-6.4*2+4(0.5*2-0.8)

-6.4*2+4(1       -0.8)  I did the multiplication in the ( ) first.

-6.4*2+4(.2)              I did the subtracting in the ( ).

-12.8+.8                    I did the multiplication by -6.4*2 and 4*.2 simultaneously

-12

I'm going to put all of this together because I think it might be easier to read:

7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)  

Plug in 2 for m

7.8 + 2(0.75*2  + 0.4)=-6.4*2 + 4(0.5*2 - 0.8)

7.8 + 2(1.5        + 0.4)= -6.4*2 + 4(1       -0.8)

7.8 + 2(1.9)                = -6.4*2 + 4(.2)

7.8 +  3.8                 =   -12.8  +.8

11.6                          =-12

This is false because 11.6 is not the same as -12.

m=2 leads to a false equation

B.

The value of m for the expression 7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8) is -2. Hence, Mia's statement is false.

Simplification in mathematical terms is a process to convert a long mathematical expression in simple and easy form.

The given equation is,

7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)

Also, Mia solved the equation and determine that the value of m is 2.

To find the value of m, simplify the expression,

7.8 + 1.5m + 0.8 = -6.4m + 2m - 3.2

1.5m + 8.6 = -4.4m - 3.2

1.5m + 4.4m = -3.2 - 8.6

5.9m = -11.8

m = -2

Mia is incorrect because the value of m is -2,  

Therefore the statement is false.

Disjunction is true because 5-3 =2 is true and 3.4=12 is also true.

3. 3 + 4 = 9 or 5 · 2 = 11

Disjunction is false because 3+4 =7 and not 9 and 5.2 =10 and not 11. Since both are false so, this disjunction is false.

sqrt(-2) + sqrt(-18)

We know sqrt(ab)= sqrt(a) sqrt(b)

sqrt(-1)sqrt(2) + sqrt(9) sqrt(-2)

sqrt(-1)sqrt(2) + sqrt(9) sqrt(2)sqrt(1)

We know the sqrt(-1) is equal to i

i sqrt(2) +3 sqrt(2) i

i sqrt(2) +3i sqrt(2)

4i sqrt(2)

(74+72+76+80+73+(AnswerB)75)÷6(total number of quizzes include the one she needed to take)=75(minimum average because she needs to get average of 75)

Answer:

f(- 5) = 13

Step-by-step explanation:

To evaluate f(- 5) substitute x = - 5 into f(x)

f(- 5) = - 3 × - 5 - 2 = 15 - 2 = 13

[tex]\huge{\boxed{y=-\frac{5}{6} x+4}}[/tex]

Parallel lines share the same slope, so the slope of the parallel line in this case must be [tex]-\frac{5}{6}[/tex].

Point-slope form is [tex]y-y_1=m(x-x_1)[/tex], where [tex]m[/tex] is the slope and [tex](x_1, y_1)[/tex] is any known point on the line.

Plug in the values. [tex]y-(-1)=-\frac{5}{6} (x-6)[/tex]

Simplify and distribute. [tex]y+1=-\frac{5}{6} x+5[/tex]

Subtract 1 from both sides. [tex]\boxed{y=-\frac{5}{6} x+4}[/tex]

Answer:

y = -5/6x   +   4        (slope - intercept form)

OR

5x + 6y -24 = 0          (standard form)

Step-by-step explanation:

What is the equation of the line that goes through the point (6,-1) and is parallel to the line represented by the equation below?

y=-5/6 x+3

To solve this;

We need to first find the slope of the the equation given

Comparing the equation given with y=mx + c, the slope (m) = -5/6, any equation parallel to this equation will have the same slope as this equation.

Since our new equation is said to be parallel to this equation the slope(m) of our new equation is also -5/6.

Now we will proceed to find the intercept of our new equation, to find the intercept, we will simply plug in the value of the points given and the slope into the formula y=mx + c and then simplify

The value of the points given are; (6, -1) which implies x=6 and y=-1  slope(m)= -5/6

y = mx + c

-1 = -5/6 (6)  +  c

-1 = -5  +  c

Add 5 to both-side of the equation to get the value of c

-1+5 = -5+5 + c

4 = c

c=4

Therefore the intercept(c) of our new equation is 4

We can now proceed to form our new equation. To form the equation, all we need to do is to simply insert the value of our slope (m) and intercept (c) into y = mx +  c

y = -5/6x   +   4

This above equation is in slope-intercept form, we can further simplify it to be in the standard form.

6y = -5x + 24

5x + 6y -24 = 0
