Note from the author:
Directions:
0) Make sure you've turned in your study guide.
On your desk - paper, pencil, calculator
On your browser - this test, Desmos links below.
In your backpack - phones, electronics, notes.
1) Take the test. If you're struggling, come back to the directions and formulae. Give it your best shot, but keep moving through the questions.
2) Some questions allow you to show your work. For these, just type what steps you took to get your answer. I may be able to give you partial credit if some of your steps are correct. You do NOT have to show your work.
3) Check your answers. Pay careful attention that you gave what the question was asking for. Check formatting especially.
4) Submit the test. Let me know if GoGuardian blocks you.
5) Close your Chromebook. Read, draw, or work on paper schoolwork quietly.

Quadratic Regression
Formulae
Change of Base: log_{b}(x) = \frac{ln(x)}{ln(b)}
Interest/Value: F=P(1+r)^{t}, where F is the final value, P is the principal/starting value, r is the interest/change rate in decimal form, and t is the time.
Compound Interest: F=P(1+\frac{r}{n})^{n\cdot t}, where n is number of compounding periods (usually 12 for months) in one full period, and t is the time (usually # of years).
Heating/Cooling Bodies: T = (T_{0}-T_{s})e^{-kt}+T_{s}, where T is the current temperature of the object, T_{s} is the ambient/surrounding temperature, T_{0} is the starting temperature of the object, t is the time, and k is a constant relating to the thermal conductivity of the object.
