The answer is C. <3 ans <11
Answer:
The distance of two complex numbers
= 9.055
Step-by-step explanation:
<u>Step(i):-</u>
Given that z₁ = 6-3i and z₂ = -3-4i
We know that 'z' represents a point on the argand plane with absicca 'x' and ordinate 'y'
Now given points are ( x₁ , y₁) = (6 ,-3) and (x₂, y₂) = (-3 , -4)
<u><em>Step(ii):-</em></u>
The distance of two points
z₁ z₂
=9.055
So
a. so 100-1/10 of 100 or 100-10=90
then second dose minus 10% or 90-9=81
third dose 81 minus 10%=81-8.1=72.9
fourth dose 72.9 minus 10% or 72.9-7.29=65.61
so after 4th dose only 65.61% are left
b. so to get it to 5% you do alot and find that it takes 27 tries to get the percent down to 5.2% and 28 doses to get it to 4.7%
