Answer:

5 faces

Step-by-step explanation:

Euler's formula for polyhedra states that

F + V - E = 2 ( F is faces, V is vertices and E is edges ), thus

F + 5 - 8 = 2, that is

F - 3 = 2 ( add 3 to both sides )

F = 5

Thus number of faces is 5

A bacteria culture begins with 15 bacteria which double in amount at the end of every hour. How many bacteria are grown during t

Eva8 [605]

The answer is 30720

A = P * rⁿ
A - the final population
r - the growth rate
P - the initial number of bacteria
n - the number of hours

We know:
A = ?
r = 2 (it doubles)
P = 15
n = 12

After 11 hours
A(11) = 15 * 2¹²
A(11) = 15 * 2048
A(11) = 30720

After 12 hours
A(12) = 15 * 2¹²
A(12) = 15 * 4096
A(12) = 61440

<span>How many bacteria are grown during the 12th hour?
A(12) - A(11) = 61440 - 30720 = 30720</span>
