Suppose that the logistic equation dx dt = kx(mx) models a population x(t) of discus fish in a lake after t months during which no fishing occurs. let us now suppose that discus fish are removed from the lake to sell it as an ornamental pet, and the rate of removal is hx fish per month (h > 0). we thus observe that fish are harvested at a rate proportional to the existing fish population, rather than at a constant rate of example.
ii 0> h 0 are t -> +∞ so the lake is eventually fished out.

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?

Which best describes how fluids change as they travel through different portions of the convection currents? they change to solids at the outer portion of the convection currents. they change to solids at the inner portion of the convection currents. they become more dense at the outer portion of the convection currents. they become more dense at the inner portion of the convection currents
