W(t) = { 17/2 - 3/2 cos((t x pi)/6) for 0< or equal to t < or equal to 6 ; 10 - 1/5 (t - 6)^2 for 6< t< or equal to 10. The depth of a river at a certain point is modeled by the function above, where W(t) is measured in feet and time t is measured in hours.
A) Find W’(8). Using correct The piecewise function f(x) is continuous at such a point if and only of the left- and right-hand limits of the pieces agree and are equal to the value of the f. ...
