Answer:

Options A and B are true

Step-by-step explanation:

In this question it is given that population of a bacterial colony doubles every 10 minutes and the function that represents the number of bacteria in colony after x minutes is [tex]3.(2)^{\frac{x}{10} }[/tex]

Now we check each option given

A. The expression [tex](2)^{\frac{x}{10} }[/tex] reveals the population of the bacterial colony increases by 100% every 10 minutes.

Let's check by putting x = 10

[tex]3.(2)^{\frac{10}{10}}=(3).(2) = 6[/tex]

Here after 10 minutes initial population which was 3 got doubled to 6. So option A is true.

B. Expression [tex](1.07)^{x}[/tex] reveals the approximate rate of increase in the population of the bacterial colony per minute.

Let's solve the expression

[tex]3.(2)^{\frac{x}{10}}=3.[(2)^{\frac{1}{10}}]^{x}=3.[1.07]^{x}[/tex]

Option B is true.

C. This option is not correct as we have already solved the expression in option B.

D. This option can't be correct because it is itself given in the question that [tex](2)^{\frac{x}{10}}[/tex] reveals that the bacterial colony increases by 100% in 10 minutes.

E. Let's check this option by putting x = 1 minute in [tex]3.(2)^{\frac{x}{10} }[/tex]

and in [tex](1024)^{x}[/tex] . If solutions of both the expressions are same then this option will be correct.

[tex]3.(2)^{\frac{x}{10} }=3.(2)\frac{1}{10}=3.(1.07)=3.21[/tex]

And [tex](1024)^{x}=(1024)^{1}=1024[/tex]

As both the solutions are different so Option E is incorrect.

F. As we have seen in option E both the expressions give different values for different values of x so Option F will be incorrect again.

Options A and B are true.

Answer:

Options A and B.

Step-by-step explanation:

The general exponential growth function is

[tex]g(x)=a(1+r)^x[/tex]

where, a is the initial value, r is rate of change, x is time.

Consider the given function is

[tex]f(x)=3(2)^{\frac{x}{10}}[/tex]          ... (1)

here, function f(x) represents the number of bacteria in the colony after x minutes.

The given function can be rewritten as

[tex]f(x)=3(1+1)^{\frac{x}{10}}[/tex]        .... (2)

On comparing (1) and (2) we get

[tex]r=1[/tex]

It means expression [tex](2)^{\frac{x}{10}}[/tex] reveals that the population of the bacterial colony increases by 100% every 10 minutes.

Using the property of exponent, the given function can be written as

[tex]f(x)=3(2^{\frac{1}{10}})^x[/tex]      [tex][\because a^{mn}=(a^m)^n][/tex]

[tex]f(x)\approx 3(1.07)^x[/tex]

It means expression [tex](1.07)^x[/tex] reveals that the approximate rate of increase in the population of the bacterial colony per minute.

Therefore, the correct options are A and B.
