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.

Part A

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

When d=0,

The initial number of bacteria in the petri dish,

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

Part B

After 5 days, when d=5

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

The elevation of a small submarine changes by -3/8 mile after each exploration. After how many explorations will the submarine's

diamong [38]

Answer:

It is after 4 explorations that the submarine's elevation would have changed by -3/2 miles

Step-by-step explanation:

From the question,

The elevation of the submarine changes by -3/8 mile after each exploration.

To determine the number of explorations it will take for the submarine's elevation to have changed by -3/2 miles, we will divide -3/2 miles by the number of miles the elevation of the submarine changes per exploration (that is, -3/8 mile),

That is,

-3/2 miles ÷ -3/8 mile

= $-\frac{3}{2} \div -\frac{3}{8}$

= $-\frac{3}{2} \times -\frac{8}{3}$

= $\frac{24}{6}$

= 4

Hence, it is after 4 explorations that the submarine's elevation would have changed by -3/2 miles.
