 Question 37617: 3) Suppose you throw a baseball straight up at a velocity of 32 feet per second. A function can be created by expressing distance above the ground, s, as a function of time, t. This function is s = -16t2 + v0t + s0 • 16 represents ½g, the gravitational pull due to gravity (measured in feet per second 2). • v0 is the initial velocity (how hard do you throw the object, measured in feet per second). • s0 is the initial distance above ground (in feet). If you are standing on the ground, then s0 = 0. a) What is the function that describes this problem? Answer: b) The ball will be how high above the ground after 1 second? Answer: Show work in this space. c) How long will it take to hit the ground? Answer: Show work in this space. d) What is the maximum height of the ball? Answer: Show work in this space.

 Question 37613: I am to solve this problem finding all real or imaginary solutions. I believe I solved it, but I question whether it is correct. The question is: 6x=19x+25/x+1 My work: 6x(x+1)=6x^2+6x Then I put it into the equation form of -6x^2-25x+25=0 I used the b^2-4(a)(c) formula which =625-4(-6)(25) The whole thing turned out to be 625-600=25 Because the outcome is positive, does it not have to have two solutions? I am unsure what the second one is? Thank you Click here to see answer by venugopalramana(3286)
