Answer:

9^{2x-1} = 2\\

Step-by-step explanation:

According to the law of logarithm;

If \ log_ab = x\\a^x = b

Given

\log_9\left(2\right)=2x-1

Comparing with the original expression;

a = 9, b = 2 and c = 2x - 1

Substitute into the result indicinal expression;

9^{2x-1} = 2\\

This gives the required exponential equation

A ferry traveled \dfrac16 6 1 ​ start fraction, 1, divided by, 6, end fraction of the distance between two ports in \dfrac37 7 3
Ugo [173]

Answer:

<em>The ferry can travel \frac{7}{18} of the distance between the two ports in one hour.</em>

Step-by-step explanation:

A ferry traveled \frac{1}{6} of the distance between two ports in \frac{3}{7} hour.

Suppose, the ferry traveled x of the distance between the two ports in one hour.

So, the <u>equation according to the ratio of "distance" to "time"</u> will be.......

\frac{\frac{1}{6}}{\frac{3}{7}} =\frac{x}{1} \\ \\ x=\frac{1}{6}\times \frac{7}{3}= \frac{7}{18}

Thus, the ferry can travel \frac{7}{18} of the distance between the two ports in one hour.

Noah and Maggie are making a rectangular picture frame.They want the length of the frame to be three inches longer than the widt
zalisa [80]

Answer:

9 inches by 12 inches

Step-by-step explanation:

So let's say <em>L</em>=length and <em>W</em>=width.

Since the problem states that the length should be 3 inches longer than the width, <em>L</em><em>=</em><em> </em>W+3

And the formula to find the perimeter of a rectangle is 2L+2W

so plug in W+3 for L and you get 2(W+3)+2W

Then distribute

2W+6+2W

Combine like-terms

4W+6

And the problem states the perimeter is 42 inches so,

4W+6=42

Subtract 6 to both sides

4W=36

Divide by 4 to both sides

W=9

So the width is 9

And to get the length, plug in 9 for W in L=W+3

L=9+3

L=12

So the length is 12
