Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>It can be rewritten as:</u>
- v(d) = 2^d, where d- number of divisions
<u>If number of divisions is 8, then:</u>
- v(8) = 2^8 = 256 virus cells
Correct choice is B
Let x = small number
y=large numebr
x+y = 90
y-4x=15
substitute
we get:
x=21
y=90-21 = 69
