Each bacterium in a petri dish splits into 2 bacteria after one day. The function b(d) = 600 • 24 models

TiliK225 [7]

Answer:

(a)Initial Number of Bacteria=600

(b) $\text{Number of bacteria after 5 days}=19200$

Step-by-step explanation:

Given an initial number $b_0$ of bacteria in a petri dish, and each bacteria splits into 2 bacteria after one day.

The function $b(d) = 600 \cdot 2^d$ models the number of bacteria, b after d days.

Given $b(d) = 600 \cdot 2^d$

When d=0,

The initial number of bacteria in the petri dish,

$b_0=b(0) = 600 \cdot 2^0=600$

After 5 days, when d=5

$b(5) = 600 \cdot 2^5=600 \cdot 32\\\text{Number of bacteria after 5 days}=19200$

Multiply and simplify.

katrin2010 [14]

ANSWER

$8 {x}^{5} {y}^{7} {z}^{2}$

EXPLANATION

The given expression is

$2 {x}^{2} {y}^{3} {z}^{2} \times 4x {y}^{4} {x}^{2}$

We multiply out to obtain,

$= 2 \times 4 \times {x}^{2} \times x \times {x}^{2} \times {y}^{3} \times {y}^{4} \times {z}^{2}$

Recall that,

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this rule to obtain,

$= 8 {x}^{2 + 1 + 2} {y}^{3 + 4} {z}^{2}$

This simplifies to
$= 8 {x}^{5} {y}^{7} {z}^{2}$
