Let the population of rabbits surviving at a time t be governed by the differential equation (dpdtt=21p(t)−200.If p(0)=100, then p(t) equals
Let αand βbe the roots of equation x2−6x−2=0. If an=αn−βn,forn≥1, then the value of 2a9a10−2a8is equal to:
A diode detector is used to detect an amplitude modulated wave of 60% modulation by using a condenser of capacity 250 pico farad in parallel with a load resistance 100 kilo ohm. Find the maximum modulated frequency which could be detected by it.
