Suppose that a colony of bacteria starts with 1 bacterium and doubles in number every half hour. how many bacteria will the colo

OverLord2011 [107]

Let $a_n$ represent the number of bacteria after $\frac{n}{2}$ hours.

so

$a_0$ is the number of bacteria after 0/2 = 0 hours

$a_1$ is the number of bacteria after 1/2 hours

$a_2$ is the number of bacteria after 2/2 = 1 hours and so on

so if we list a few terms of this sequence, we have:

$a_0=1$

$a_1=1*2$

$a_2=1*2*2$

$a_3=1*2*2*2$

$a_4=1*2*2*2*2$

so clearly, $a_n$ , the number of bacteria after $\frac{n}{2}$ hours, is equal to $2^{n}$ .

$a_4_8$ is the number of bacteria after

$\frac{n}{2}=\frac{48}{2}= 24$ hours.

Thus, we calculate $a_4_8$ , which is $2^{48}$ .

Answer: the number of bacteria after 24 hours is $2^{48}$ .

Find x. Round to the nearest tenth.

Answer:

<u>x = 466.7 feet</u>

Step-by-step explanation:

Finding the top angle of the triangle :

They are complementary
90° - 31°
59°

Take the tan value of this angle to find y :

tan 59° = 400/y
1.66427948 =400/y
y = 400 / 1.66427948
y = 240.344248

Using Pythagorean Theorem to find x :

y² + 400² = x²
x = √(240.344248)² + 160000
x = √57765.3575 + 160000
x = √217765.357
<u>x = 466.7 feet</u> (nearest tenth)
