The high Roller Ferris wheel was completed in 2014 in Las Vegas. It

is the largest in the world, with a height of 550 ft and a 520 ft diameter. Riders enter a cabin at the bottom of the wheel and are taken on a rotation that lasts 30 min. Write a sine function that models the height of a cabin for the duration of the ride.

During a soccer match, Tony, at point A, passes the ball to Eoin, at point C, to avoid the defender at point B. Eoin then kicks the ball towards the 7.32 m wide net in an attempt to score. The path of the ball is modeled by the absolute value function . Suppose a Cartesian plane is superimposed over the opponent’s half of the pitch such that the opposite corners of the field of play have the coordinates (0, 60) and (90, 0), as shown.

a.At what point does Eoin receive the ball?

b. If player B does not intercept the ball, verify whether or not the ball makes it into the goal.

c.If Tony passes the ball from point (5,36), state the domain and range of the absolute value function, within the context of this situation.

can someone help me with this question is super confusing.

cube with side length x has been modified by adjusting its side length x has been modified by adjusting its length, width and height. A student determined a function of the form v(x)=(x+a)(x+b)(x+c) can be used to represent the volume of the new box for different values of x, and then she graphed the function.

a.based on the graph ,predict how the side lengths of the original cube changed.(hint:what do the zeros of the function represent?

b.determine a polynomial function of the form v(x)=(x+a)(x+b)(x+c) that's matches the function in the graph .

c.which parts of the graph are realistic?(hint:all sides must be positive.using two negative side lengths to give positive volume is not realistic.)
