    Kwa mazoezi yafuatayo, fanya meza ya maadili kwa kila seti ya equations parametric, graph equations, na ni pamoja na mwelekeo; kisha kuandika equation Cartesian.

    48. \(\left\{\begin{array}{l}x(t)=3 t^{2} \\ y(t)=2 t-1\end{array}\right.\)

    49. \(\left\{\begin{array}{l}x(t)=e^{t} \\ y(t)=-2 e^{5 t}\end{array}\right.\)

    50. \(\left\{\begin{array}{l}x(t)=3 \cos t \\ y(t)=2 \sin t\end{array}\right.\)

    51. mpira ni ilizinduliwa na kasi ya awali ya 80 miguu kwa sekunde kwa pembe ya\(40^{\circ}\) kwa usawa. Mpira hutolewa kwa kimo cha futi 4 juu ya ardhi.

    1. Find equations parametric kwa mfano njia ya mpira.
    2. Wapi mpira baada ya sekunde 3?
    3. Je! Mpira ni muda gani?
