Question: Solve the given maximum and minimum problems

(FF) The height (in ft) of a flare shot upward from ne ground is given by \(s=112 t-16.0 t^{2}\), where \(t\) is the time (in sec.) What is he greatest height to which the flare goes?

(GG) A de-generator with an internal resistance i develops v volts. If he variable resistance in the circuit is r, the power generated is \(p=\frac{v^{2}}{r+r}\). What resistance r gives the maximum power?

(HH) in deep water, the velocity of a wave is \(v=k \sqrt{\frac{2}{a}+\frac{a}{l}}\), where a and k are constant in the minimum velocity.

(II) A rectangular hove is to be cut in a wall for a vent. If the perimeter of the hole is 48 in. and the length of the diagonal is a minimum, what are the dimensions of the hove ?
