Answer:
The exponential function is
Step-by-step explanation:
Given
be the number of hours.
number of bacteria cells.
And we know that an exponential function is ,where
is a positive real number, and in which the argument
occurs as an exponent
The petri dish has bacteria cells we can say that
In the equation as is function of time and
will vary as
for respective hours.
To find the value of we have to understand that it is dependent on percent increase if there is increment of
then
So the exponential function will be ,plugging the values it will be equivalent to
Check:
So in first hour the cells will increased by a quantity of cells.
The number of cells after an hour in the petri dish
That can also be from the formula.
So the exponential function is
will increase exponentially as the value of
increase.
First, you need to analize and understand the problem, then you must choose and strategy. There is a wide variety of strategies to solve a mathematical problem, in this case, you can use the following, which is based on the information given above:
1. You have that t<span>he sum of three consecutive even integers is </span>
<span>, therefore, you can given the variable </span>
<span> to the first integer, the second even integer is </span>
<span> and the third one is </span>
<span>.
2. Calculate x:
