2 inches : 8 feet

simplified scale:

1 inch : 4 feet

Answer:

Radius, r = 26.57 cm and diameter = 53.14 cm

Step-by-step explanation:

Given that,

The circumference of a coin, C = 167 cm

We need to find the radius and the diameter of the coin.

The formula for the circumference of a circle is given by :

[tex]C=2\pi r[/tex]

Where

r is radius of coin

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{167}{2\pi}\\\\r=26.57\ cm[/tex]

Diameter, d = 2r

d = 2(26.57) cm

= 53.14 cm

Hence, this is the required solution.

Answer:

The answer for first one is,

[tex]2(x - 3)[/tex]

sorry I don't know the answer for second one.

-2x + 6 + 6x = 6 (2x - 3) this is the equation

-2x + 6 + 6x = 12x - 18 distributive property has been applied

4x + 6 = 12x - 18 like terms have been added

6 = 8x -18 4x has been subtracted from both sides

24 = 8x -18 has been added to both sides

3 = x 8 has been divided from both sides

I hope this helps! Let me know if I need to explain more or if I got something wrong. Have a nice day!

Answer:

The range of the function in ascending order is:

Range R = {-2, 0, 2, 4}

Step-by-step explanation:

Given the function

f(x) = 2-2x

We know that the domain of the function is the set of input or arguments for which the function is real and defined.  

In other words,  

As the domain of the function is given such as

Domain D = {-1, 0, 1, 2}

Determining the range

We also know that range is the set of values of the dependent variable for which a function is defined.  

In other words,  

Range refers to all the possible sets of output values on the y-axis.

As the domain is

Domain D = {-1, 0, 1, 2}

FOR x = 1

substitute x = -1 in the function

f(x) = 2-2x

f(-1) = 2-2(-1) = 2+2=4

so

at x = -1, y = 4

FOR x = 0

substitute x = 0 in the function

f(x) = 2-2x

f(-1) = 2-2(0) = 2-0=2

so

at x = 0, y = 2

FOR x = 1

substitute x = 1 in the function

f(x) = 2-2x

f(-1) = 2-2(1) = 2-2=0

so

at x = 1, y = 0

FOR x = 2

substitute x = 2 in the function

f(x) = 2-2x

f(-1) = 2-2(2) = 2-4=-2

so

at x = 2, y = -2

Thus combining all the output or y values correspond to the given input values, we get the range of the function.

Thus, the range of the function in ascending order is:

Range R = {-2, 0, 2, 4}

Answer:

-19 1/9

Step-by-step explanation:

Answer:

x = 5.943

Step-by-step explanation:

Reference angle = 23°

Side opposite to reference angle = x

Adjacent side = 14

Therefore, we would apply TOA to find x.

Thus:

tan (23) = x/14

Multiply both sides by 14

14 × tan(23) = x

5.94264742 = x

x = 5.943 (to 3 decimal places)

Answer:

The interval of converges of a power series is the interval of input values for which the series converges.

Answer:

A. x is ⅓ of y

Step-by-step explanation:

x : y

= 1 : 3

Therefore,

x = 1

y = 3

If so x is 1/3 of y

Answer:

a. 76 cm

b. 16 in.

c. 225 cm

Step-by-step explanation:

a. Converting 30 inches to centimetres:

When y(inches) = 30, x (centimetres) = 76

So, 30 in. = 76 cm

b. When x (cm) = 40, y (in.) = 16

So, 40 cm = 16 in.

c. Given that a fence is 7 ft 6 in. high, and 1 ft = 12 in., to find the height of the fence in cm, first convert the height to in.

Convert 7ft to inches:

If 1 ft = 12 in., then,

7 ft = 7*12 = 84 inches

The height of the fence in inches = 84 + 6 = 90 inches

Using the graph, find the unit rate using any point on the line, say (100, 40):

Unit rate = y/x = inches/centimeters =

Unit rate (m) = 40/100 = ⅖

Write an equation for the line:

To do this, substitute m = ⅖ into y = mx

Equation: y = ⅖x

Let's convert the height of the fence, 90 inches, to centimetres:

To convert to cm, substitute y = 90 into y = ⅖x

Thus:

90 = ⅖*x

5*90 = 2x

450 = 2x

Divide both sides by 2

450/2 = x

225 = x

Height of the fence in cm = 225 cm

How can I complete step 3 in proof and review it what is step 3

Answer:

[tex]\frac{dr}{dh} =-\frac{r}{2h}[/tex]

Step-by-step explanation:

The volume of a cylinder is given by the formula:

V = πr²h,

Where V is the volume, r is the radius of the cylinder and h is the height of the cylinder.

We are to express the rate of change of the radius of the clay with respect to the height of the clay in terms of height h and radius r.

That means we express dr / dh in terms of height h and radius r. To do this, we have to first differentiate the volume with respect to the height, i.e. find dV / dh:

V = πr²h

[tex]\frac{dV}{dh}= \frac{d}{dh} (\pi r^2h)\\\\\frac{dV}{dh}= \pi r^2 + 2\pi rh \frac{dr}{dh} \\\\The\ volume\ is\ constant\ hence\ \frac{dV}{dh}=0.\ We\ get\ that:\\\\0= \pi r^2 + 2\pi rh \frac{dr}{dh}\\\\- \pi r^2 =2\pi rh \frac{dr}{dh}\\\\ \frac{dr}{dh}=-\frac{\pi r^2}{2\pi rh}\\\\ \frac{dr}{dh}=-\frac{r}{2h}[/tex]:

Step-by-step explanation:

Answer:

The greatest y-intercept c = 6

Step-by-step explanation:

we know that

        slope-intercept form y = mx +c

a) Given that  f(x) = [tex]6x + \frac{1}{6}[/tex]

                       [tex]y = 6x + \frac{1}{6}[/tex]

   comparing    y = mx +c

  slope of the line m = 6 and Y - intercept c= 1/6

b)    Given that  f(x) = [tex]6x -6[/tex]

                        y = 6x -6

   comparing    y = mx +c

  slope of the line m = 6 and Y - intercept c= -6

c)

    Given that  f(x) = [tex]\frac{1}{6} x +6[/tex]

                        y =  [tex]\frac{1}{6} x +6[/tex]

   comparing    y = mx +c

  slope of the line m =  [tex]\frac{1}{6}[/tex]  and Y - intercept c= 6 ( greatest intercept)

d)

 Given that  6 k(x) = x

                     k(x) = [tex]\frac{1}{6} x[/tex]

                        y = [tex]\frac{1}{6} x[/tex]

   comparing    y = m x +c

 The slope of the line m =[tex]\frac{1}{6}[/tex]  and Y-intercept c=0

Final answer:-

The greatest y-intercept c = 6

Answer:

3

Step-by-step explanation:

x x6=18

x=3

Answer:

(18=6 times x)  you would divide both sides by 6 since inverse operations and to leave the x by itself. 18/6 is 3 so 3=x
