1. Apply the distributive property: (3q - 1)(10q + 7) = 3q(10q) + 3q(7) - 1(10q) - 1(7)
2. Calculate each term:

3q \cdot 10q = 30q^2

,

3q \cdot 7 = 21q

,

-1 \cdot 10q = -10q

,

-1 \cdot 7 = -7

3. Combine like terms:

30q^2 + 21q - 10q - 7 = 30q^2 + 11q - 7

Answer: 30q^2 + 11q - 7

User One of the applications of the derivative of a function is its use in Physics, where a function that at every instant t associates the number s(t), this function s is called the clockwise function of the movement. By deriving the time function we obtain the velocity function at time t, denoted by v(t). A body has a time function that determines its position in meters at time t as S(t)=t.³√t+2.t . Present the speed of this body at time t = 8 s.
