The graph of a sinusoid always function passes through (0,1) has a maximum point at (Pi/2,3) and a subsequent point at (7pi/6,3)

determine the amplitude, Midline and range of the function

find the sine and cousin function with these characters 

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.

can somebody help me i dont understand this question .... please

For the following cell, write the equations of the reactions occurring at the cathode and the anode, and an equation for the overall or net cell reaction. Calculate the standard cell potential. Cr(s)   Cr2+ (aq). Sn2+ (aq) Sn(s)

question 1 helppp please ive speed 1 hour trying to figure this out.. thanks

a.solve 6cosθ sin θ - 2 cos θ = 0,0< θ < 2π

b. give the general solution to 6cosθ sin θ - 2 cos θ = 0.

i need help with these two question... please , its really confusing.

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.
