Roughly 12000 people in a certain country are diagnose a thyroid cancer every year which accounts for 1% of all cancer cases that occurs in women 3 times as frequently as men fortunately thyroid cancer can be treated successfully and many cases with radioactive iodine or i-131 this unstable form of iodine has a 1/2 life of 8 days and is given in small doses measured in milicuries
a)suppose a patient is given initial dose of 80 milicuries. find a function that gives the amount of i-131 in the body after t> 0(more than or equal) days
b) how long does it take for the amount of i131 to reach 15% of the initial dose
c) finding the initial dose to give a particular patient is a critical calculation. how does the time to reach 15% of the initial dose change if the initial dose increased by 5%

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.
