is it \[8p=-2x^2-100\]?

  • misty1212
so i guess your job is to solve for \(x\) right?

Thanks for the help @misty1212 greatly appreciate it. And yes find X
misty1212
  • misty1212
maybe start with \[8p+100=-2x^2\] then divide by \(-2\) and get \[-4p-50=x^2\]
misty1212
  • misty1212
last step would be to take the square root and get \[x=\pm\sqrt{-4p-50}\]

That's not a answer choice :9 This is so confusing.

Derek kicks a soccer ball off the ground and in the air, with an initial velocity of 31 feet per second. Using the formula H(t) = -16t2 + vt + s, what is the maximum height the soccer ball reaches?
misty1212
  • misty1212
is it really 31, or could it be 32?
anonymous
  • anonymous
idk -_- @satellite73
misty1212
  • misty1212
i am asking if you made a typo is all it would be tons easier if it was "initial velocity of 32" instead of "31"
anonymous
  • anonymous
31
misty1212
  • misty1212
ok then if it is 31 it is 31 first coordinate of the vertex of \(y=ax^2+bx+c\) is \(-\frac{b}{2a}\) which, in your case, is \[-\frac{31}{2\times( -16)}=\frac{31}{32}\]
misty1212
  • misty1212
if it was initial velocity of 32 you would get a 1, which would be a lot easier to deal with, but whatever now you have to compute \[h(\frac{31}{32})\]

i would use a calculator http://www.wolframalpha.com/input/?i=-16%2831%2F32%29%5E2%2B31%2831%2F32%29

at max height H(t)=0 -32t+v=0 t=v/32 t=31/32 H(31/32)=-16(31/32)^2+31*31/32 = 15

Last one A toy rocket was launched from the ground. The function f(x) = -16x2 + 128x shows the height of the rocket f(x), in feet, from the ground at time x seconds. What is the axis of symmetry of the graph of f(x), and what does it represent?
