Answers
First, we need to solve for
X
in the equation:
7 = \frac{X}{20}
To isolate
X
, multiply both sides by 20:
7 \times 20 = X
Calculate:
X = 140
Therefore, the solution is
X = 140

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.Β³βt+2.t . Present the speed of this body at time t = 8 s.

Exercise The temperature T in degrees Celsius of a chemical reaction is given as a function of time t, expressed in minutes, by the function defined on ΒΏ by: T (t )=(20 t +10)eβ0.5t. 1) What is the initial temperature? 2) Show that T' (t )=(β10 t +15)eβ0 .5t. 3) Study the sign of T' (t ), then draw up the table of variations of T . We do not ask for the limit of T in +β. 4) What is the maximum temperature reached by the reaction chemical. We will give an approximate value to within 10β2. 5) After how long does the temperature T go back down to its initial value? We will give an approximate value of this time in minutes and seconds.
