Answer:
Step-by-step explanation:
Suppose that at time we have x mold cells. We are told that after 12 minutes the amount present is double. That is a
we have 2x cells. Then, at
we have (2x)*2 = 4x. We can continue as follows
we have (4x)*2 = 8x.
we have (8x)*2 = 16x
(one hour later) we have (16x)*2 = 32x.
So after one hour from now we have 32x cells.
Answer:
The next two terms are: 1.05 and 1.20
Step-by-step explanation:
Given
Required
Write out the next two terms
Since it is a linear sequence; first, we calculate the common difference (d)
or
Express as decimals
or
(in both cases)
So, we add 0.15 to 9/10, to get the next term
Add 0.15 to 1.05, to get the next term
<em>The next two terms are: 1.05 and 1.20</em>
