  • Let the first integer be x.

  • Let the second integer be x + 1 .

  • Let the third integer be x + 2 .

<h2><u>According</u><u> to</u><u> the</u><u> </u><u>question</u></h2>

x + ( x + 1 ) + ( x + 2 ) = -42

Opening the brackets and simplifying :

x + x + 1 + x + 2 = -42

3x + 3 = -42

Now , solving equation :

\bf  \rightarrow  \: \:3x  \: + \:  3  \: =  \: -42

\bf \rightarrow \: \: 3x  \: = \:  -42  \: - 3

\bf  \rightarrow \:3x \:  = \:  -45 \:

\bf  \rightarrow \:x \:   =  \:  \frac{ - 45}{ \: 3}  \\

\bf  \rightarrow \:x \:   =  \:   \cancel\frac{ - 45}{ \: 3}   \:   \: ^{ - 15}  \\

\bf  \rightarrow \:x \:   =   \:  - 15

{\boxed{ \Large{ \red{ \rm{ \underline{ Now \:  \:  substitute}}}}}}

\bf  \implies  \: \:x \:    =  \:  - 15

\bf  \implies \:  \:x  \:  +  \: 1 \:  =  \:  - 15 \:  + \:  1 \:  =  \:  - 14

\bf  \implies \:  \:x  \:  +  \:2 \:  =  \:  - 15  \: + \:  2 \:  =  \:  - 13

-15 , -14 and -13 are the three consecutive integers.

A bacteria culture starts with 1000 bacteria and the number doubles every 40 minutes. (a) find a formula for the number of bacte
vfiekz [6]

The formula for the number of bacteria at time t is 1000 x (2^t).

The number of bacteria after one hour is 2828

The number of minutes for there to be 50,000 bacteria is 324 minutes.

<h3>What is the number of bacteria after 1 hour?
</h3>

The exponential function that can be used to determine the number of bacteria with the passage of time is:

initial population x (rate of increase)^t

1000 x (2^t).

Population after 1 hour : 1000 x 2^(60/40) = 2828

Time when there would be 50,000 bacteria : In(FV / PV) / r

Where:

  • FV = future bacteria population = 50,000
  • PV = present bacteria population = 1000
  • r = rate of increase = 100%

In (50,000 / 1000)

In 50 / 1  = 3.91 hours x 60 = 324 minutes
