Actually Welcome to the Concept of the Absolute value.

so we get as,

let, y = 2 - 9i

so the absolute value is |y|

[tex] |y| = \sqrt{ {2}^{2} + {9}^{2} } [/tex]

so we get as,

|y| =

[tex] \sqrt{81 + 4} = \sqrt{85} [/tex]

so the absolute value is

[tex] \sqrt{85} [/tex]

Answer:

7°

Step-by-step explanation:

If the temperature was -5 and it increased by negative 12, it's asking you to add -5 and 12

-5+12=7

slope = -2

y intercept = 6

=====================================================

Explanation:

Let's find the slope

m = (y2-y1)/(x2-x1)

m = (2-4)/(2-1)

m = -2/1

m = -2

The slope is -2

Let's use this slope along with the first point to get the y intercept

y = mx+b

y = -2x+b ... plug in the slope we found earlier

4 = -2*1+b ... plug in the coordinates of the point (1,4)

4 = -2+b

4+2 = -2+b+2 .... adding 2 to both sides

6 = b

b = 6

The y intercept is 6

The equation y = mx+b turns into y = -2x+6 since m = -2 is the slope and b = 6 is the y intercept.

Answer:

1.5lb/ounces

Step-by-step explanation:

Given:

Mass of dry ice Carmen uses  = 12lb

Mass of root beet  = 8ounces

Unknown:

Ratio/Proportional constant for number of pounds to number of ounces of root beer extract  = ?

Solution:

To solve this problem,

    Ratio = [tex]\frac{number of pounds of dry ice}{Ounce of root beer}[/tex]

    Ratio  = [tex]\frac{12lb}{8ounces}[/tex]   = 1.5lb/ounces

Answer:

Let the price of one senior citizen ticket be sc and the price of one student ticket be st.

Let's write equations using the information given and the variables above:

=> 5sc + 15st = $137.50

=> 20sc + 44st = $430

Hmm.. We can multiply 5sc by 4 to get 20sc.

=> 4(5sc) + 4(15st) = 4($137.50)

=> 20sc + 60st = $550

Now we can subtract the second equation from the first to determine the price of a student ticket.

  20sc + 60st = $550

-  20sc + 44st = $430

=> 16st = $120

=> st = $7.5

So, the price of a student ticket is $7.5.

Answer: It will be needed 864 square feet of glass to cover the Skywalk floor.

Step-by-step explanation: The figure below shows the area in question.

Area of a circle is given by

[tex]A=\pi.r^{2}[/tex]

The walkway is a semicircle. Then, area will be:

[tex]A=\frac{\pi.r^{2}}{2}[/tex]

The area that will be covered with glass is the area between the outer and the inner circles. So, area is

[tex]A_{t}=A_{outer}-A_{inner}[/tex]

[tex]A_{t}=\frac{\pi.r_{o}^{2}}{2}- \frac{\pi.r_{i}^{2}}{2}[/tex]

[tex]A_{t}=\frac{\pi}{2}(32.5^{2}-22.5^{2})[/tex]

[tex]A_{t}=\frac{\pi}{2}(550)[/tex]

[tex]A_{t}=[/tex] 864

To cover the Skywalk floor is needed 864[tex]ft^{2}[/tex] of glass.

Answer:

[tex]\frac{d}{dx}(-xcos3x)= 3x \ sin(3x)- cos(3x)[/tex]

Step-by-step explanation:

Use the Product Rule for derivatives, which states that:

In the function we are given, [tex]f(x)=-x \cos3x[/tex], we can break it up into two factors: -x is being multiplied by cos3x.

Now, we have the factors:

Before using the product rule, let's find the derivative of cos3x using the chain rule and the power rule.

Now let's apply the product rule to f(x) = -xcos3x.

Simplify this equation.

Multiply x and 3 together and remove the parentheses.

Therefore, this is the derivative of the function [tex]f(x)=-xcos3x[/tex].

Hi there!

[tex]\large\boxed{f'(x) = -cos3x + 3xsin3x}[/tex]

[tex]f(x) = -xcox3x\\\\\text{Use the product rule and chain rule to solve for the derivative:}\\\\\frac{dy}{dx}= -cos3x + (-x * (-sin3x) * 3)\\\\= -cos3x + 3xsin3x[/tex]

Step-by-step explanation:

The base is 3.5 because it is the one being multiplied to itself for 5 times.

5 is the exponent because it tells us that we have to multiply 3.5 to itself 5 times.

Answer:

gradient is 0.35

Step-by-step explanation:

The gradient or slope of the line is 1/4.

The slope of a line indicates the direction and the steepness of the line. The formula for the slope of a line passing through the points (x₁,y₁) and (x₂, y₂) is m = (y₂-y₁)/(x₂-x₁).

The graph of the line is given.

Note that the line passes through the point (0,1) ad (4,2).

The gradient of the line is nothing but the slope of the line.

The slope of the line is:

m = (2-1)/(4-0)

m = 1/4

Hence, the gradient or slope of the line is 1/4.

Answer:

no it is not the same.

Step-by-step explanation:

it is not the same because 13/4 is smaller than 3/14. 3 1/4 includes a whole number, and 13/4 doesn't.

Answer:

15. Yes, it is larger than 14.

Step-by-step explanation:

In this problem,

[tex]\frac{3}{5}[/tex]×25,

25 is divided by 5 and the remainder is 5, So,

3×5 = 15,

4) ΔSTW ≅ ΔBFN . So, corresponding parts of congruent triangles are congruent.

a) BN = SW                                        d) m∠W = m∠N

  BN = 9 cm                                           m∠W = 82°

b) TW = FN                                        e) m∠B = m∠S

TW = 14 cm                                            m∠B = 67°

c) BF = ST                                          f) m∠B + m∠N + m∠F = 180°

  BF = 17 cm                                                 67 + 82 + m∠F = 180

                                                                            149 + m∠F = 180

                                                                                     m∠F = 180 - 149

                                                                                      m∠F = 31°          

5) ΔUVW ≅ ΔTSR

UV = TS

12x - 7 = 53

   12x   = 53+7

   12x = 60

      x = 60/12

      x = 5

UW =TR

3z +14 = 50

    3z = 50 - 14

   3z = 36

     z = 36/3

    z = 12

SR =VW

5y - 33 = 57

     5y = 57 + 33

     5y = 90

       y = 90/5

       y = 18

7) ΔPHS ≅ ΔCNF

∠C = ∠P

4z - 32 = 36

      4z = 36 + 32

       4z = 68

        z = 68/4

       z = 17

∠H = ∠N

6x - 29 = 115

  6x     = 115 + 29

      6x = 144

        x = 144/6

       x = 24

∠P + ∠H + ∠S = 180   {Angle sum property of triangle}

36 +115 + ∠S = 180

      151   + ∠S = 180

                ∠S = 180 - 151

               ∠S = 29°

∠F = ∠S

3y - 1 = 29

   3y = 29 + 1

  3y = 30

    y = 30/3

    y = 10

8) ΔDEF ≅ ΔJKL

DE = 18    ;  EF = 23

DF = 9x - 23

JL= 7x- 11

DF = JL           {Corresponding parts of congruent triangles}

      9x - 23 = 7x - 11

9x  - 7x - 23 = -11

        2x - 23 = -11

               2x = -11 + 23

               2x = 12

                 x = 12/2

                x = 6      

JK   = DE           {Corresponding parts of congruent triangles}

3y - 21  = 18

       3y = 18 + 21

Answer:

Input is the number in the first column of the table. This is the number that you start with to follow the rule if the rule is given. You would also use this number to figure out what the rule is if it is not given.

Step-by-step explanation:

An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (\begin{align*}x\end{align*}-value) by 3 to find each output number (\begin{align*}y\end{align*}-value).
