Answer:

[tex]a = \sqrt[3]{\frac{3}{2}}[/tex]

Step-by-step explanation:

Given

[tex]\frac{180}{80}=\frac{80}{80}*a^6[/tex]

Required

Solve for a

[tex]\frac{180}{80}=\frac{80}{80}*a^6[/tex]

[tex]\frac{180}{80}=1*a^6[/tex]

[tex]\frac{180}{80}=a^6[/tex]

[tex]a^6 = \frac{180}{80}[/tex]

[tex]a^6 = \frac{18}{8}[/tex]

[tex]a^6 = \frac{9}{4}[/tex]

Take the square root of both sides

[tex]\sqrt{a^6} = \sqrt{\frac{9}{4}[/tex]

[tex]a^3 = \frac{3}{2}[/tex]

Take cube rooth of both sides

[tex]a = \sqrt[3]{\frac{3}{2}}[/tex]

Step-by-step explanation:

The height of the given Ferris wheel can be described with the aid of a

sinusoidal function.

The height above the ground in terms of the angle turned, a, is

presented as follows;

The height above the ground in terms of the distance traveled, s, is

presented as follows;

Reason:

The general form of an equation of a Ferris wheel is presented as follows;

f(a) = A·sin(a + C) + D

Where, the amplitude, A = The radius = 37 ft.

D = The midline = Height above the ground + The amplitude

D = A + 0.6 = 37 + 0.6 = 37.6

The 6 O'clock is the lower most position, therefore, at the start, where, 'B·t + C' = 0, we have;

f(a) = A·sin(0 + C) + D

Therefore

f(a) = 37·sin(0 + C) + 37.6 = 0.6

f(a) = 37·sin(C) = 0.6 - 37.6 = -37

[tex]sin(C) = \dfrac{-37}{37} = -1[/tex]

C = sin⁻¹(-1) = [tex]-\dfrac{\pi}{2}[/tex]

The equation of Ferris wheel is presented as follows;

Which gives the equation of the height above the ground (in feet) in terms

of the number of radians, a, you have swept out from the 6 O'clock

position is given as follows; Ferris ;

Part 2

s = a·r = a·A

Therefore;

[tex]a = \dfrac{r}{s} = \dfrac{A}{s} = \dfrac{37}{s}[/tex]

Plugging the value of s into the above equation gives the function that

determines the height above the ground (in feet) in terms of the number of

feet traveled g(s) as follows;

Answer:

y = 120

Step-by-step explanation:

y = 4x (corresponding angles)

y + 2x = 180

substitute the value of y into the second equation

4x + 2x = 180

6x = 180

x = 30

now that we have the value of x, plug it into either equation and solve for y

y = 4 (30)

y = 120

Answer:  After they've played 8 games, they will have the same amount of money remaining.

Step-by-step explanation:

Represent the number of games by the variable x and the remaining amount of money by the variable y.  

 Deanna's situation can be represented by the equation   y = 15 - 0.75x  

Lisa's situation can be represented by the equation   y = 13 - 0.50x  

Now to find out how many games they will have the same amount of money remaining, you have to use substitution and solve for x.

15 - 0.75x = 13 - 0.50x

-13               -13

        2 - 0.75x = - 0.50x

             +0.75x      +0.75x

  2 =  0.25x  

 x  = 8

Answer:

Step-by-step explanation:

I need a layout

Answer:

Density is defined as:

Density = mass/volume.

We know that:

For liquid A:

Density = 70kg/m^3

Mass = 1400kg

Then the volume is:

Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3

For liquid B:

Density = 280 kg/m^3

Volume = 30m^3

We can find the mass of liquid B as:

mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg

We know that liquid C is a mixture of liquid A and B.

Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:

Mass of liquid C = 1400kg + 8400kg = 9800kg

The same happens for the volume, then:

Volume of liquid C = 30m^3 + 20m^3 = 50m^3

Then the density of liquid C is:

Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3

Answer:

Mean=76

Median=72.5

Step-by-step explanation:

Mean= 70+71+72+73+74+96

                         456/6=76

Median = 70,71,72,73,74,96

               72+73=145/2=72.5

Mean= 76

Median= 72.5

The first step is to rearrange the numbers

70, 71, 72, 73, 74, 96

1. mean= sum of terms/number of terms

= 70+71+72+73+74+96/6

= 456/6

= 76

2. Median can be described as the middle number, the median can be calculated as follows

= 72+73/2

= 145/2

= 72.5

Hence the mean is 76 and the median is 72.5
