Question

A cart moves along a track with position x(t)=2t5−t3+4t−8x(t) = $$2t^5$$ - $$t^3 + 4t - 8 $$meters. Which expression gives its instantaneous velocity function?

Accepted Answer

10t4−$$3t2+410t^4$$ - $$3t^2 + 4$$

Answer

10t4−3t2−$$810t^4$-3t^2-8$$

Answer

8t4−$$2t2+48t^4$$ - $$2t^2 + 4$$

Answer

2t6−$$t4+4t2t^6$$ - $$t^4 + 4t$$
