Answer:

The average speed = 55 miles per hour

Step-by-step explanation:

Given the information

  • Distance covered by Kenneth = 184.25 miles
  • Time taken by Kenneth to cover the distance =3\frac{7}{20}=\frac{67}{20}=3.35\:hours

As we know that the average speed can be found using the formula:

Average\:speed\:=\:\frac{Total\:Distance\:covered}{Total\:Time\:taken\:to\:cover\:the\:distance}\:

As

  • Distance covered by Kenneth = 184.25 miles
  • Time taken by Kenneth to cover the distance =3\frac{7}{20}=\frac{67}{20}=3.35\:hours

So,

Average\:speed\:=\:\frac{184.25}{3.35}

                        = 55 miles per hour

Therefore, the average speed = 55 miles per hour

Keywords:  speed, time

A Ferris wheel has a diameter of 380 feet and the center of the wheel is 195 feet above the ground. The wheel makes a complete t
Aleksandr [31]

Answer:

<u><em>y = -190 cos(π t / 120) + 195</em></u>

Step-by-step explanation:

<em>General form of a sinusoidal function: y = A cos(Bt - C) + D </em>

<em> </em>

<em>Now generally a cosine function starts at the maximum value, so to start at the minimum value, flip the cosine function by making it negative. </em>

<em> </em>

<em>A is the amplitude of the curve and will be the radius of the ferris wheel. Therefore, A = 380 / 2 = 190 feet. </em>

<em> </em>

<em> 2π / B is the period of the curve and will be the time to complete one full rotation. The time to complete one full rotation is given as 4 minutes. Convert this into seconds to get period = 4 minutes * (60 seconds / minute) = 240 seconds. Therefore, B = 2π / period = 2π / 240 seconds = π / 120. </em>

<em> </em>

<em> C/B is the phase shift, or horizontal shift of the graph. Since the negative cosine function already starts at the minimum value, there is no phase shift so C/B = 0, meaning C = 0. </em>

<em> </em>

<em> D is the vertical shift and will be the height of the center of the ferris wheel. Therefore, D = 195 feet. </em>

<em> </em>

<em> Your final function will be:</em>

<u><em>y = -190 cos(π t / 120) + 195</em></u>

Reika [66]

Answer:

<h2><u>E</u><u>k</u>sponent</h2>

\sf{ \large{ \boxed{ \red{ {a}^{ \frac{n}{m}  }  =  \sqrt[m]{ {a}^{n} } } } }}

\sf{ {2}^{ \frac{4}{3} } }

=  \sqrt[3]{ {2}^{4} }

=   \sqrt[3]{2 \times 2 \times 2 \times 2}

=   \boxed  {\bold{\sqrt[3]{16}(c.) }}

Let f(x) = 2x – 3 and g(x) = 3x – 2. Find the value.
Sholpan [36]

Answer:

Ok:

Step-by-step explanation:

So f°g . means f(g(x)). (The ° should be more center and bigger but I don't know to do that on a keyboard). f(g(x)) means that you replace the x in f(x) with the g(x) function. i.e:

if f(x) = 2x+2

and g(x) = x^2

f(g(x)) = 2x^2+2.

Similarly, in this case, we get f(x) = 2x-3 and g(x) = 3x-2.

Then, f(g(x)) or f°g(x) is 2(3x-2) - 3.

And we plug in -2 to solve:

2(3(-2)-2)-3.

and get -19.

Check if I am wrong because everyone makes mistakes but that is the way to solve this.
