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

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

A surveyor wants to know the length of a tunnel built through a mountain. According to his equipment, he is

MrMuchimi

Answer:

Length of the tunnel is 51.7 meters

Step-by-step explanation:

We are given that,

The surveyor is located 54 meters from one entrance at an angle of 56°.

The surveyor is located 31 meters from one entrance at an angle of 13°.

Let the length of the tunnel = x meters

So, using the law of cosines, we get,

$x^2=54^2+31^2-2\times 54\times 31\times \cos 69$

i.e. $x^2=2916+961-3348\times 0.3584$

i.e. $x^2=3877-1199.9$

i.e. $x^2=2677.1$

i.e. x = 51.7 meters

Hence, the length of the tunnel is 51.7 meters

let 'p' = number of pints

16 = 36

1 p

cross-multiply: 16p = 36

p = 36/ 16, which is 9/ 4, or 2 1/4
