 Question 484167: HSuppose an astronaut on the Moon throws a baseball upward. The astronaut lets go of the ball 2 meters above the ground with an initial velocity of 10 meters per second. How long does it take for the ball to hit the ground (H=0)? (Use the quadratic formula to solve this problem, show all work). Write a statement to interpret your results. How much longer will the ball stay in the air on the moon than the similarly-thrown baseball on Earth? Demonstrate this mathematically and with a sentence. Click here to see answer by chessace(471)

 Question 487112: Good Morning, I am trying to solve the following equations x2 - 2x - 13 = 0 i am not sure if i am finding the square root of each side completely here is the work i have completed so far The problem: X2 - 2x - 13 = 0 Step #1 Move the constant term to the right side of the equation. The constant term is - 13 X2 - 2x = 13 Step #2 Multiply each term in the equation by four times the coefficient of the term x 4x2 - (2x4 =) 8 = (13 x 4 =) 52 4x2 - 8 = 52 Step #3 Square the coefficient of the original x term and add it to both sides o the equation Original Coefficient = 2 (2 squared =) 4 4x2 - 8 + 4 = 52 + 4 4x2 - 8 + 4 = 56 Step # 4 Take the square root of both sides 4x2 - 8 + 4 = 56 Please help me thank You Bethany Keitzer Click here to see answer by nerdybill(7090)

 Question 487150: We are trying to Factor the equation 2x^4 - 4x^3 + 8x^2. We factor out 2x^2 out. 2x^2(x^2 - 2x + 4) We then input into the quadratic equation (-(-2) +/- sqroot of -2^2 - 4(1)(4)) / 2(1). That give us (2 +/- sqroot -12) / 2. should be able to reduce that to 1 +/- (sqroot 3)i. So now we need to understand how to write the answer. Would it be 2x^2(x - (1 + [sqroot 3]i)(x + (1 + [sqroot 3]i)?? Some how this just does not appear to me to be the correct answer.
