Answer:

m∡A = 41.4°

m∡B = 48.6°

m∡C = 90°

a = 3[tex]\sqrt{7}[/tex]

b = 9

c = 12

Step-by-step explanation:

to find the length of side 'a' I used the Pythagorean Theorem to get:

a² + 9² = 12²

a² + 81 = 144

a² = 63

a = [tex]\sqrt{63}[/tex] which equals [tex]\sqrt{9}[/tex][tex]\sqrt{7}[/tex] which is 3[tex]\sqrt{7}[/tex]

to find m∡B I found the arcsin(B) = 9/12 to get 48.6

to find m∡A I subtracted the sum of 90 + 48.6 from 180°

Answer:

50ft x 3.14 = 157ft

Step-by-step explanation:

It's asking for the circumference.

circumference formula: [tex]C = 2\pi r[/tex]

To give you a better idea of the concept:

To make it simple, in a circle, there is the radius, diameter, and then the circumference.

Radius: The distance half way across the circle (see attachment below).

Diameter: The distance across the circle (see attachment below).

Circumference: The distance around the circle (see attachment below).

As you see, the radius is only half way across, so 2 times the radius would give us the full distance across (diameter).

(But this doesn't matter for this question because it already gave you the diameter (50ft), this was only so I could maybe help you understand the concept a bit more).

Your question:

Alright, it's asking for the circumference; all you have to do is the diameter (50 ft) times pi (3.14).

[tex]50ft *3.14=157ft[/tex]

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

a) The equation of graph of the transformation of function is given by the relation d ( x ) = p ( x - 2 ) + 3

b) The sequence of transformation is translate 1 to the left, scale vertically by 1/2 , then reflect over the x-axis.

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be represented as p ( x )

Now , the value of p ( x ) is

d ( x ) = p ( x - 2 ) + 3

The function is shifted 2 units to the right and 3 units up do match all the data points on the graph

b)

Let the parent function be y = k ( x )

Let the transformed function be y = -( 1/2 ) k ( x + 1 )

So , the series of transformation is given by

Translating 1 unit to the left , scale vertically by 1/2 , then reflect over the x-axis.

Hence , the transformed function is y = -( 1/2 ) k ( x + 1 )

Expected count frequency= 17*50/88= 9.659

Step-by-step explanation:

             Members Living More            Members Living Less     Total

               Than 25 Miles                         Than 25 Miles

              from the Waterfall                from the Waterfall

Low                25                                          17                              42

Medium          8                                           21                              29

High               5                                            12                              17

Total             38                                            50                           88

We see that the total of the high row is 17 and the total of the members living less than 25 miles  from the waterfall is 50 .

So using the formula :

Expected count frequency= row total * column total/ grand total

                                         = 17*50/88= 9.659

All the expected frequencies can be found in a similar way and then compared to the observed frequency to test the chi square.

Answer:

8 1/2

Step-by-step explanation:

Answer:

x = {-1/5, 1}

Step-by-step explanation:

(5x - 2)² - 1 = 8

Add 1 to both sides

(5x - 2)² = 9

Take the square root of both sides

5x - 2 = ±3

------------------------------

Solution I for 5x - 2 = +3

5x - 2 = 3

add 2 to both sides

5x = 5

Divide both sides by 5

x = 1

------------------------------

Solution II for 5x - 2 = -3

5x - 2 = -3

add 2 to both sides

5x = -1

Divide both sides by 5

x = -1/5

-------------------------------

x = {-1/5, 1}
