1 answer:
Fiesta28 [93]3 years ago

Answer:

Below in bold.

Step-by-step explanation:

(A). s = (1/3)t^3 - 3t^2 + 9t + 7

To find the velocity at time t we find the derivative:

V = ds/dt = 3*1/3 t^2 - 3*2t + 9

V = t^2 - 6t + 9,

Acceleration is found by finding the derivative of the velocity:

A = 2t - 6.

(B). Acceleration after 1 second = 2(1) - 8

= -6 ms^-2.

(C).  When V = 0

acceleration = 0 ms^-1.

<u><em>Step-by-step explanation: </em></u>

<u><em> </em></u>

<u><em>Given: </em></u>

<u><em> </em></u>

<u><em>w(h) represents how many hours per week </em></u>

<u><em>(f.g)(x) or f(g(x)) means first apply g(), then apply f() i.e. applying function f to the results of function g. </em></u>

<u><em> </em></u>

<u><em>Now we have c(w(h)), this means first we apply w(h) which will give us hours per week and then we'll apply function 'c' on the results of 'w' (that is number of hours for weeks painted). As result we'll get number of canvas </em></u>per week!
