the rate is usually the number in the parentheses in an exponential function, now the tell-tale piece is that, if the rate is less than 1, we have a Decay expression, and if the rate is more than 1, then is Growth.
well, let's see 0.365 is less than 1, so it's Decay.
The amount of heat (in KJ) released when 3.5 moles of CH₄ react is 3115 KJ
<h3>Balanced equation</h3>
CH₄ + 2O₂ -> CO₂ + 2H₂O ΔH = 890 KJ
From the balanced equation above,
1 mole of CH₄ reacted to release 890 KJ of heat energy.
<h3>How to determine the heat energy released by 3.5 moles of CH₄</h3>
From the balanced equation above,
1 mole of CH₄ reacted to release 890 KJ of heat energy
Therefore,
3.5 moles of CH₄ will react ro release = 3.5 × 890 = 3115 KJ of heat energy
Thus, 3115 KJ of heat energy were released from the reaction

I would feel better if you'd explain how you "know" that a "same-day" ticket is $15.
"<span>The combined cost of one advance ticket and one same-day ticket is $35." This would imply that the cost of one advance ticket is $(35-15), or $10.
Check by substitution to determine whether $15 and $10 are correct. If not, please show your work, so that someone else or I could step back in and help.

Answer:
34% decrease
Step-by-step explanation:
(V1-V2)/V1x100
450-297=153
153/450=0.34
0.34 x 100=34
34% decrease

Answer:the percent of increase in price is 7.69%
Step-by-step explanation:
The yearbook was sold for $26 at the beginning of the year. This means that the initial price of the year book was $26.
The price has increased to $28. The amount by which it was increased would be the current price - the initial price. It becomes
28 - 26 = $2
The percent of increase in price would be
Increase/initial price × 100
It becomes
2/26 × 100 = 7.69%
