The price per share of a stock can be approximated by the function S(t) = (27 - 4t) +20, where t is time (in years) since the stock was purchased. Find the average price of the stock over the first 8 years. Round the answer to two decimal places if necessary. A. $341.33 B. $64.27 C. $31.50 D. $42.67 urse

2. To graphically represent the value of t, based on your data, consider equation 8: V.(t) = Voerc Because RC = t, this is equivalent to Vi(t) = Voez. Taking the natural logarithm of both sides yields In(V.) = (-1)+ + In(Vo) (Recall that In(ex) = x and In(ab) = In(a) + In(b)). Observe that this has the form of a linear equation y = mx + b for which y = ln(Vc), x=t, the slope m= (-), and the...

Write an expression for the instantaneous voltage V(t) delivered by an ac generator supplying 120 V rms at 60 Hz. Assume the voltage is 0 at time t = 0, and leave the factors in exact form; do not round their values, write the argument of the sinusoidal function to have units of radians, but omit the units.
