Explain how to solve 2^x + 1 = 9 using the change of base formula log base b of y equals log y over log b. Include the solution
elena55 [62]

Answer:

x=2.170

Step-by-step explanation:

The given equation is 2^{x+1}=9.

We take logarithm of both sides to base 2 to get:

\log_2(2^{x+1})=\log_29

Apply the power rule of logarithms to get:

x+1=\log_29

We now apply the change of base formula:

x+1=\frac{\log_{10}9}{\log_{10}2}

x+1=\frac{0.9542}{0.3010}

x+1=3.1701

x=3.1701-1

x=2.1701

To the nearest thousandth, x=2.170

Alissa owns a lovely country store. She buys 6 jars of honey for $65 and then sells 5
scoundrel [369]

She will have to buy 8 jars for her to make a profit of $214

<h3>How to calculate the profit percent</h3>

If Alissa buys 6 jars of honey for $65, then;

  • Cost price = 6(65) = $390

If she sells 5 jars for $72, the selling price will be:

Selling price = 5(72) = $360

If she is to make a profit od $214

Profit = selling price - Cost price

214 = n(72) - 390
72n = 214 + 390
72n = 604
n = 8

Hence she will have to buy 8 jars for her to make a profit of $214
