    How close will the two ships get?

    I got it to be: After the expansion and derivative dD/dt=200t-98.84/(the rest here doesn't matter cause I'm setting other side to zero)

    How close will the two ships get?

    D^2=(-3.53+6t-0)^2+(3.53-8t)^2 I did derivative. Set it to 0. Got 0.7 Thats not the answer I'm suppost to plug time into the D^2 and get the distance correct?

    How close will the two ships get?

    **** or is it A(8t,0) B(3.53,-3.53+6t) My guess is that's right if not I quit school
  12. T

    How close will the two ships get?

    ah crap... A is (8t,0)
  13. T

    How close will the two ships get?

    A's position at t=0 is (0,0) A's position as a function of time is (3.53-8t,0) B's position as a function of time is (3.53,-3.53-6t)

    How close will the two ships get?

    yes those are the coordinates.from the origin (0,0) using pythagorean theorem, i use 5sin45=a=3.53, b=3.53
  15. T

    How close will the two ships get?

    yes I have a drawing. I used the sin law to find the distance of the 2 sides. Coordinates (3.53,0) and (3.53,-3.53) By the way how do you put spaces in latex coding I tried \\ it didnt work
