Suppose a population of 10 spiders doubles in size every month. How
many spiders will there be after 1 year? (5pts)
(a) 10,628,820
(b) 40,960
(c)81,920
(d) 5,314,410

Answer 1

Answer:

b. 40,960

Step-by-step explanation:

There is probably some equation you could do for this but I find it simpler just to take 10 and multiply it by 2 and then keep multiplying the answers by 2 twelve times so:

10*2=20

20*2=40

40*2=80

80*2=160

160*2=320

320*2=640

640*2=1280

1280*2=2560

2560*2=5120

5120*2=10240

10240*2=20480

20480*2=40960

Answer 2
