Answer 196899 by Alan3354(30993)   on 2010-02-11 20:24:48 (Show Source):
You can put this solution on YOUR website!
Suppose Charlie O’Brian of the Braves hits a
baseball straight upward at 150 ft/sec from a height of 5 ft.
a) Use the formula to determine how long it takes the ball
h(t) = -16t^2 + 150t + 5 (I had to provide my own formula)
h = 0
-16t^2 + 150t + 5 = 0
 Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc) Quadratic equation (in our case ) has the following solutons: For these solutions to exist, the discriminant should not be a negative number. First, we need to compute the discriminant : . Discriminant d=22820 is greater than zero. That means that there are two solutions: . Quadratic expression can be factored: Again, the answer is: -0.0332156501954231, 9.40821565019542. Here's your graph:

-------------
t =~ 9.408 seconds (Ignore the negative value)
-----------------------------------
b) Use the accompanying graph to estimate the maximum
height reached by the ball
h(t) = -16t^2 + 150t + 5
I don't see a graph, so I'll use the equation
The max height is at the vertex, when t = -b/2a
t = -150/-32 = 75/16 seconds
h(75/16) =~ 356.5625 feet = max height

 Linear-equations/268685: Write the slope-intercept form of the equation of the line through the give point with the given slope: through: (-2,-3), slope = undefined1 solutions Answer 196876 by Alan3354(30993)   on 2010-02-11 19:02:14 (Show Source): You can put this solution on YOUR website!Undefined slope means "vertical", or parallel to the y-axis. For all values of y, x = -2 ------------- --> x = -2 There is no y-intercept, and the slope is undefined, so x = -2 is the equation. y = .... is not possible.

(The right side has no effect on the slope) -------- The slope of 6x + ry = ... is -6/r --------------- a) parallel means the same slope -6/r = -3/4 r = 8 ---------- b) perpendicular means the slope is the negative inverse, = 4/3 -6/r = 4/3 r = -4.5
 Linear-equations/268582: Solve graphically. y=-1/3x-1 4x-3y=18 I feel dumb because I know once you show me how to do this I will go AHHH that's how but for the life of me I cannot figure this out. Please help. Thanks1 solutions Answer 196806 by Alan3354(30993)   on 2010-02-11 15:57:13 (Show Source): You can put this solution on YOUR website!The graphs are 2 straight lines. 2 points is sufficient to plot a straight line. Where they cross is the solution. ---------------- y = -x/3 - 1 Pick 2 values for x and find y. x...y 0...-1 --> (0,-1) 6...-3 --> (6,-3) Plot the 2 points, draw a line thru them ------------ Do the same for the 2nd eqn. Where they cross is the solution.
 Numeric_Fractions/268584: 9/10 -1/4- 1/2= ? anyone can give me the answer and the steps it took to get the answer thanks 1 solutions Answer 196804 by Alan3354(30993)   on 2010-02-11 15:52:15 (Show Source): You can put this solution on YOUR website!9/10 -1/4- 1/2= ? ----------------- Find a common denominator and change all the fractions to that DEN. It doesn't matter if it's the LCD or not. On a test, don't waste time finding the LCD, just multiply them all together. ------------ 10*4*2 = 80 --> 72/80 - 20/80 - 40/80 = 12/80 = 3/20 -------
