Aperson's prescription for his new bifocal eyeglasses calls for a refractive power of -0.0675 diopters in the distance-vision part and a power of 1.20 diopters in the close-vision part. assuming the glasses rest 2.00 cm from his eyes and that the corrected near-point distance is 250 cm, determine the near and far points of this person's uncorrected vision.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
