Answer the problem below

Answer:

Length of the arc = π/50 cm

Step-by-step explanation:

Hello,

The diagram above is a circle and the to find the length of the arc, we need to know the formula for that.

Length of an arc = θ/360 ×2πr

θ = 3π/5

radius (r) = 6cm

Substitute the values into the equation

[(3π/5) / 360] × 2πr

Length of an arc = 3π/5 × ¹/₃₆₀ × 2π(6)

Length of an arc = (3π x 12π) / (5×360)

Length of an arc = 36π/1800

Length of an arc = π/50cm

The length of the arc is π/50cm

Also, I am super late to the question, but...hope it still helps?

A hexagon is composed of 6 congruent equilateral triangles. Each equilateral triangle has interior angle of 60 degrees. Adding 6 such angles together gets you to 360 degrees. So we've done one full rotation and covered every bit of the plane surrounding a given point. Extend this out and you'll be able to cover the plane. A similar situation happens with rectangles as well (think of a grid, or think of tiles on the wall or floor)

In contrast, a regular pentagon has interior angle 108 degrees. This is not a factor of 360, so there is no way to place regular pentagons to have them line up and not be a gap or overlap. This is why regular pentagons do not tessellate the plane. The same can be aside about decagons and octagons as well.

Answer: 1/5 , 1/2, and 5/6

Step-by-step explanation:

given;

probability that the cube shows a three (3) or five (5).

probability that it stops on yellow.

1. the probability p of the spinner stopping on yello  

= 1/5 times

a cube has 6 sides

2. probability that it shows a 3

this is going to be 3 divided by the total sides on the cube which is 6

P = ( 3 ) = 3/6

Divide both side by 3

= 1/2.

3. probability that it shows a 5,

this is going to be 5 divided by the total sides on the cube which is 6

P = ( 5 )

  = 5/6.

Answer: Annette will take 6 hours to do the entire job alone.

Step-by-step explanation:

Given: Time taken by Kelly to do [tex]\dfrac{1}{5}[/tex] of job = 2 hours

i.e. Time for complete job done alone by Kelly =[tex]5\times2=10\ hours[/tex]

Rest of work = [tex]1-\dfrac{1}{5}=\dfrac{4}{5}[/tex] of the job

[tex]\dfrac{4}{5}[/tex]  of the complete job done by both Kelly and Annette in 3 hours

Time would be taken by then to do entire job together = [tex]3\times\dfrac{5}{4}=3.75\ hours[/tex]

Let t be the time taken by Annette to do job alone.

Then, as per situation

[tex]\dfrac{1}{3.75}=\dfrac{1}{10}+\dfrac{1}{t}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{3.75}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{4}{15}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{6}\\\\\Rightarrow\ t=6[/tex]

hence, Annette will take 6 hours to do the entire job alone.

Answer:

0.9

Step-by-step explanation:

This is a sine triangle. We have the hypotenuse (7) and an angle opposite of x (6). The formula for sine is opposite/hypotenuse; 6/7 = 0.8571428571428571. This, rounded to the nearest tenth, is 0.9.

Answer:

59 degrees

Step-by-step explanation:

Sin = opposite / hypotenuse

In this case sin is 6/7

To find the angle of this we need to use the arcsin, or sin^-1 function

Arcsin(6/7) = 58.9972809 degrees

This gets rounded to 59 degrees

Answer: √3

Step-by-step explanation:

Hi, since the situation forms a right triangle we have to apply the next trigonometric function.  

Sin α = opposite side / hypotenuse  

Where α is the angle (30°), the hypotenuse is the longest side of the triangle (in this case 2), and the opposite side is x. (not t or 2)

Replacing with the values given:  

Sin 30 = x /2

Sin 30 (2) = x

x=1

Applying the Pythagorean theorem:

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (2) and a and b are the other sides.  

2^2 = t^2 + 1^2

4= t^2 +1

4-1 = t^2

3 = t^2

√3 = t

Answer:

Option B

Step-by-step explanation:

As shown in the picture, g(x) is the red one which can be obtained by translating f(x) - the blue one toward +x-axis direction 4 units.

=> g(x) = f(x) + 4 = |x| + 4

Answer: Choice D

g(x) = |x-4|

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

Explanation:

Replacing x with x-4 shifts the xy axis four units to the left. If we fix the blue V shape to not move while the xy axis does move, then it gives the illusion of the V shape moving 4 units to the right to end up producing the red curve.

You can use a table of values to compare the two functions or you could use a graphing tool to confirm the answer.

--------

Extra info:

Choice A will move the blue graph 4 units down

Choice B will move the blue graph 4 units up

Choice C will move the blue graph 4 units to the left

Answer: B.) $275

Step-by-step explanation:

Insurance cost :

Housing insurance - - - 50c per $100

Content insurance - - - 25c per $100

House valuation = $50,000

50c = $0.5

Therefore insurance cost on House:

Valuation × insurance cost

($50,000 / $100) * $0.5

$500 × $0.5 = $250

25c = $0.25

Insurance cost on content :

($10,000 / $100) × $0.25

$100 × $0.25 = $25

Total insurance cost :

$250 + $25 = $275

Answer:

Part A Part B Part C explained

Step-by-step explanation:

PART A: Extrema: relative minimums (4,-2) and maybe (7,-3) (uncertain because it’s an endpoint), relative maximums (6,0) and maybe (1,6) (uncertain because it’s an endpoint)

Zeros: (6,0), somewhere between t = 3 and t = 4 since the graph changes from positive to negative, and somewhere possibly between t = 6 and t = 7 unless the graph hits (6,0) and stays negative.

End behavior: We can guess that as x approaches infinity, the functions approaches negative infinity, and as x approaches negative infinity, the function approaches infinity.

Intervals of increase and decrease: Increasing on (4, 6), decreasing on (1, 4) and (6, 7)

PART B: The relative minimums indicate that the two lowest temperatures occurred on day 4 at -2°F and day 7 at -3°F. The relative maximums indicate that the weekly highs were day 1 at 6°F and day 6 at 0°F.

The zeros of the function represent when the temperature in Johnstown was 0°F. This happened sometime between days 3 and 4 and on day 6.

In the context of the problem, it doesn’t make sense to go an infinite number of degrees below zero. And, the end behavior is ignored because of the restricted range.

The intervals of increase indicate when the temperature is rising, and the intervals of decrease indicate when the temperature is dropping. The intervals where the values are positive indicate when the temperature is above 0°F. The intervals where the values are negative indicate when the temperature is below 0°F.

PART C: The domain is restricted to the number of days the town recorded the temperature. So, the domain is [1, 7].

The range represents the range of temperatures of Johnstown over the course of one week. So, the range is [-3, 6].

Answer:

Part A was missing the last so this is the correct answer.

Extrema: relative minimums (4,-2) and maybe (7,-3) (uncertain because it’s an endpoint), relative maximums (6,0) and maybe (1,6) (uncertain because it’s an endpoint)

Zeros: (6,0), somewhere between t = 3 and t = 4 since the graph changes from positive to negative, and somewhere possibly between t = 6 and t = 7 unless the graph hits (6,0) and stays negative.

End behavior: We can guess that as x approaches infinity, the functions approach negative infinity, and as x approaches negative infinity, the function approaches infinity.

Intervals of increase and decrease: Increasing on (4, 6), decreasing on (1, 4) and (6, 7)

Positive and negative intervals: Positive from 1 to somewhere between t = 3 and t = 4, and negative from somewhere between t = 3 and t = 4 to t = 6, and from some point after t = 6 to t = 7.

But other than that everything else was correct and thank you.

Answer:

x+y = 14

Step-by-step explanation:

x+y+xy = 54

1+x+y+xy = 55

(1+x)(1+y) = 55

(1+x)(1+y) = 5*11

If x and y are integers,

1+x = 5    => x = 4

1+y = 11   =>  y = 10

or

1+x = 11   => x = 10

1+y = 5   =>  y = 4

In either case, x+y = 14

The solution to this system is [tex]x = 4[/tex] and [tex]y = 10[/tex]. Then, [tex]x+y = 14[/tex].

Let be [tex]x + y + x\cdot y = 54[/tex], then we proceed to modify the expression by algebraic means:

The only divisors of 55 is 5 and 11, respectively. Hence, we have the following  system of linear equations:

[tex]x + 1 = 5[/tex] (1)

[tex]y + 1 = 11[/tex] (2)

The solution to this system is [tex]x = 4[/tex] and [tex]y = 10[/tex]. Then, [tex]x+y = 14[/tex].

Answer:

x = 4.2

Step-by-step explanation:

To calculate for the value of x, we must first calculate the value of y as shown in the attached photo.

The value of y can be obtained as follow:

Angle θ = 30°

Opposite = y

Hypothenus = 6

Sine θ = Opposite /Hypothenus

Sine 30° = y/6

Cross multiply

y = 6 × Sine 30°

y = 3

Therefore, the value of y is 3.

Now, we can obtain the value of x as follow:

Angle θ = 45°

Adjacent = y = 3

Hypothenus = x

Cos θ = Adjacent /Hypothenus

Cos 45° = 3/x

Cross multiply

x × Cos 45° = 3

Divide both side by Cos 45°

x = 3/Cos 45°

x = 4.2

Therefore, the value of x is 4.2

Answer:

Answer:

Two figures are similar if they have the same shape:

For example, two rectangles are similar if the quotient between length and wide is the same.

Now, we know that one of the rectangles is 6cm by 4cm.

The quotient of the lengths is 6cm/4cm = 3/2

Here we have a problem; you wrote

" Another rectangle with adjacent

sides o on and x cm ....."

I guess that this means:

The other triangle has one side with a measure of x cm, and the other side will have the lenght A, a constant number that you can complete after.

Now, if this new triangle is similar to the first one, then we must have;

If x > A.

x/A = 6cm/4cm = 3/2

x = (3/2)*A.

if x < A

A/x = 6cm/4cm = 3/2

x = (2/3)*A

There you have the two possible values of x, for a known A.

Answer:

The correct option is;

Choice A 4·(n - 3) - 6·n

Step-by-step explanation:

The given expression is

Which gives;-6·n+(-12)+4·n

- 12 + 4·n-6·n = -2·n - 12 = - (2·n + 12)

The options given are Choice A and/or Choice B;

(Choice A) 4·(n - 3) - 6·n

Which can be simplified as follows;

4·(n - 3) - 6·n = 4·n - 12 - 6·n

Which gives;

4·n - 12 - 6·n = 4·n  - 6·n- 12 = -2·n - 12 = -(2·n + 12)

Therefore, 4·(n - 3) - 6·n is equivalent to -6·n+(-12)+4·n

For choice B, we have;

2·(2·n - 6) which gives;

2·(2·n - 6) = 4·n - 12

Therefore, 2·(2·n - 6) is not equivalent to -6·n+(-12)+4·n

Which gives the correct option as Choice A.
