Mathematics: I need help with my project. I’m stumped :/ The Ferris wheel I’ve chosen is the high roller Ferris wheel in Las Vegas. This is what I know: Height-550ft Radius-260ft Midpoint-290ft Height from the ground: 30ft Full rotation: 30 min Increments: 28 Sin equation: y=260sin(π/15x) + 290 These are my questions: I need help with the fourth bullet point in part 1 and the second equation (shadow being cast on the ground) in part 2. (I’m pretty sure my sin function is the first equation. And then the 3rd

Hi there! Given the equation below.

$\large{r + \sqrt{x} = 9}$

First is to subtract both sides by r-term to isolate x-term.

$\large{r + \sqrt{x} - r = 9 - r} \\ \large{ \sqrt{x} = 9 - r}$

Because the x-term is in square root form. We have to square both sides to get rid of the square root.

$\large{( \sqrt{x})^{2} = {(9 - r)}^{2} } \\ \large{x = {(9 - r)}^{2} }$

Alternative Solution

$\large{x = {r}^{2} - 18r + 81}$

Answer

x = (9-r)² x = r²-18r+81

Both answers work. Any questions about this can be asked through comment.
