a passenger is riding a ferris wheel. the graph shows the height, in feet, of the passenger as a function of time. move values to the boxes to create a function, (h(t)), that models the height, in feet, of the passenger after (t) minutes on the ferris wheel. (h(t)=-squarecos(squarepi t)+square) (\frac{1}{3}) 3 5 20 25 40

Answer

Explanation:

Step1: Determine the amplitude

The amplitude $A$ of a cosine - type function $y = A\cos(Bx - C)+D$ is half of the vertical distance between the maximum and minimum values. The maximum height is $45$ feet and the minimum height is $5$ feet. So, $A=\frac{45 - 5}{2}=\frac{40}{2}=20$.

Step2: Determine the period

The period $T$ of the function is the time it takes for one complete cycle. From the graph, the period $T = 1$ minute. The formula for the period of a cosine function $y=\cos(Bx)$ is $T=\frac{2\pi}{B}$. Since $T = 1$, then $1=\frac{2\pi}{B}$, and $B = 2\pi$. In the given form $h(t)=-A\cos(B\pi t)+D$, when $B = 2\pi$, the coefficient of $t$ inside the cosine function is $2$.

Step3: Determine the vertical shift

The vertical shift $D$ is the mid - height between the maximum and minimum values. $D=\frac{45 + 5}{2}=25$.

Answer:

$h(t)=-20\cos(2\pi t)+25$
