materials, but you must work independently and may not consult anyone (and confirm this with your submission).
You may take as much time as you wish, provided you turn in your quiz no later than Sunday, July 9. Show work/explanation. Answers without any work may earn little, if any, credit. You may type or write your
work in your copy of the quiz, or if you prefer, create a document containing your work. Scanned work is acceptable

7776 State the corresponding exponential form of this logarithmic equation. Determine the numerical value of log 6 1
777 6 in simplest form. 2. Use an appropriate change of base formula to approximate log 3 36 to the nearest hundredth. 3. Expand log x3 y 2
√ 10 z ( ) and simplify as much as possible. Assume all quantities represent positive real numbers. 4. Use the properties of logarithms to write the expression as a single logarithm and, if possible,

where t = year and h(t) = home-ownership rate, in percent. Using the model, what was the homeownership rate in 1990, to the nearest tenth of a percent? 8. A cup of hot coffee was placed in a room maintained at a constant temperature of 69 degrees, and
