Proofs are used to confirm or disprove mathematical statements

The missing expression in the proof is : \log_b((b^{xy})

<h3>How to complete the proof</h3>

From the question, the first two steps are:

\log_b(M^y)

\log_b((b^x)^y)

By the properties of exponents, we have:

\log_b((b^{xy})

The above expression represents the missing expression in the proof of the logarithmic expression

Hence, the missing expression is : \log_b((b^{xy})

A sample of oxygen gas is confined at 127°c and 0.80 atm. if volume of the container holding the gas stayed the same, what would
sveticcg [70]

Based on the calculations, the pressure of this gas sample at 27°C is equal to 0.17 atm.

<h3>How to determine the final pressure.</h3>

In order to calculate the final pressure of an ideal gas at constant volume, we would apply Gay Lussac's law.

Mathematically, Gay Lussac's law is given by this formula;

P\;\alpha \;T\\\\P=kT

<u>Where:</u>

  • P is the pressure.
  • T is the temperature.
  • k is the constant of proportionality.

Substituting the given parameters into the formula, we have;

\frac{P_1}{T_1} =\frac{P_2}{T_2} \\\\\frac{0.80}{127} =\frac{P_2}{27} \\\\0.0063 =\frac{P_2}{27}\\\\P_2 = 0.0063 \times 27

Final pressure = 0.17 atm.

Kelsey had $65 to spend on books. Each book cost $5. 50, and there was a $7. 50 fee for shipping. She let b equal the number of
Charra [1.4K]

Answer:

The inequality symbol is incorrect because she can spend up to and including $65.

The expression 5. 50b + 7. 5 is correct because $5. 50 per book is 5. 50b and that is added to the shipping fee of $7. 50 to determine the total purchase price.

Explanation:

The inequality should be 5.50b + 7.5 ≤ 65 because she can use less than $65 or all $65 to spend on books.

Also, the shipping fee is for all the books she buys combined, not for each individual book so the left side of the inequality should read 5.50b + 7.5.
