The accommodation limits for a nearsighted person's eyes are 20.0 cm and 60.0 cm. that is, this person's unaided eye has a near point of 20.0 cm and a far point of 60.0 cm. when this person wears his glasses, he can see faraway objects clearly. what is the closest distance at which he can see objects clearly when wearing his glasses?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
