Answer:

x = 3/2

Step-by-step explanation:

9^x = 27

Rewrite both terms as powers of 3

9 = 3^2 and 27 = 3^3

3^2^x = 3^3

We know that a^b^c = a^(b*c)

3^(2x) = 3^3

The bases are the same, so the exponents need to be the same

2x= 3

Divide by 2

2x/2 = 3/2

x = 3/2

Given the data shown below, which of the following is the best prediction for the number of years it will take for the populatio

aleksley [76]

We will have the following:

Using exponential regression we will have that the line of best fit will be:

$f\mleft(x\mright)=8585.658603*1.399211892^x$

Now, we will have that:

$\begin{gathered} 300000=8585.658603*1.399211892^x\Rightarrow34.94199034=1.399211892^x \\ \\ \Rightarrow x=\frac{ln(34.94199034)}{1.399211892}\Rightarrow x= \end{gathered}$

So, the approximation using linear regression gives us as solution approximately 29.7 years; thus the closest one to match is then

Answer:

$1 \dfrac{13}{15}$

Step-by-step explanation:

$2 \dfrac{1}{5} - \dfrac{1}{3} =$

$= \dfrac{11}{5} - \dfrac{1}{3}$

$= \dfrac{33}{15} - \dfrac{5}{15}$

$= \dfrac{28}{15}$

$= 1 \dfrac{13}{15}$
