Find the velocity v(t)v(t) and speed ∥v(t)∥∥v(t)∥ of a particle whose motion is described by x=6t3−9t2,y=3,z=2t2−4t+2
Nesterboy [21]
Let \mathbf p(t)=(x(t),y(t),z(t)) denote the particle's position. Then its velocity is given by

\mathbf v(t)=\dfrac{\mathrm d\mathbf p}{\mathrm dt}=(x'(t),y'(t),z'(t))
\mathbf v(t)=(18t^2-18t,0,4t-4)

The speed is then given by the absolute value/magnitude/norm of the velocity function,

\|\mathbf v(t)\|=\sqrt{(18t^2-18t)^2+(4t-4)^2}

A $40 backpack is in sale for $28. What is the % of change
aliya0001 [1]
$ 40 ..... 100 %
$ 28 ..... x %

x = \frac{28 \cdot 100}{40} = 70

The % of change is 70 %.

This is equivalent with:
- the final price ($ 28) is 70 % from the initial price ($ 40)
- the initial price ($ 40) was reduced with 30% giving the new price as:
40 - 40 \cdot \frac{30}{100} = 28
