    3. Aurora hit a baseball with an initial velocity of 70 feet per second at an angle of 30° with the horizontal. The ball hit her bat when the ball was 3 feet above the ground.

    (a) No one interferes with the ball. How long does it take the ball to hit the ground? Round your answer to the nearest hundredth of a second. Show all your work.

    (b) How far did the ball travel horizontally? Use your answer from Part (a) in your calculations. Round your answer to the nearest tenth of a foot. Show all your work.

    pre calc help needed ?

    this is a 2 part problem in which I completed the first part but need help with the second part. 

    The first question was to simplify these complex expressions. and match the ones that yield a similar answer (you can see from the photo)

    The part I need help with is this question---

    "Determine the modulus of each of the complex numbers in the matching pairs. List these moduli in order from smallest to largest. Use the letters of the matching pair in your listing"

    What is the polar form of the equation?

    (x+2)^2+y^2=4

    r(r+4sinθ)=0

    r(r+4cosθ)=0

    r^2=4rcosθ

    r^2=4rsinθ

    2. 

    What is the rectangular form of the polar equation?

    θ=−7π/6

    y=√3x

    y=-√3/3x

    y=-√3x

    y=√3/3x

    3.What are the rectangular coordinates of the polar coordinates (3√2,−π/6) ?

     Enter values rounded to the nearest hundredth.

    4.What is the rectangular form of the polar equation?

    r−rsinθ=4

    y=8x^2−2
