Answer: 
Step-by-step explanation:
Given: The diameter of the Ferris wheel= 100 feet
therefore, the radius of the Ferris wheel= 50 feet
Also, the highest point of the wheel is 125 feet.
Since , y axis represents the center of the wheel.
The center of the wheel= (0,125)
The equation of circle with center (h,k) and radius 'r' is given by :

Thus, the equation of the circle with center (0,125) and radius=50 is given by :-

The solution set for the inequality expression is (-∞, -6)
<h3>Solving inequalities</h3>
Inequality are expressions that does not involve an equality sign.
Given the following parameters
-3x + 3 > -21
Subtract 3 from both sides
-3x + 3 - 3 > 21 - 3
-3x > 18
Divide both sides by -3
-3x/-3 < 18/-3
x < -6
Hence the solution set for the inequality expression is (-∞, -6)

Answer:
9
Step-by-step explanation:
Answer is 12.73
Use Pythagorean theory
Split square into two right triangles with diagonal line. To find the diagonal
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
162= c^2
Take square root of both sides
12.73 = c
