1. a super-deadly strain of bacteria is causing the zombie population to double every two days. currently, there are 25 zombies. after how many days will there be 25600 zombies?
2. use the function from the previous question. if the current population is 5,000,000,000 people, after how many days will there be no humans left?

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
