Answer:

  A:

  • x = (20√3)/3
  • y = (40√3)/3

Step-by-step explanation:

Side length ratios in a 30°-60°-90° "special" triangle are (shortest to longest):

  1 : √3 : 2

Comparing to the given side lengths, we have ...

  1 : √3 : 2 = x : 20 : y

Making these ratios the same gives ...

  x = 20/√3 = (20√3)/3

  y = 2x = (40√3)/3

These values match choice A.

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>

Is the square root of infinity still infinity?.
hram777 [196]
The square root of infinity is still infinity, or rather, undefined or indeterminate. For example, if you take the square root of a big number, you will still have a big number as a result, now if you make the number even bigger, the square root will also get bigger, now imagine what will happen if this number is infinite.
