1. (Mon) A room measures 8.6 m wide by 12.4 m long by 4.1 m high. What is the volume of the room in cm 3 (5 pts / 5 min)

2. Volume = l x w x h Vol = (8.6m)(12.4m)(4.1m) Vol = 437.22 m 3 437.22 m 3 Vol = 4.37 x 10 8 cm 3 (Mon) A room measures 8.6 m wide by 12.4 m long by 4.1 m high. What is the volume of the room in cm 3 1 m 100 cm 1 m

3. (Tue) You are standing 10 m from a tree. If you look up at an angle of 44.5° you see the top of the tree. How tall is the tree? (5 min / 5 pts)

4. Tanθ = Opp/Adj Tan(θ) = Height/Distance Tan(44.5°) = Ht/10m (10m)tan(44.5°) = Ht Height = 9.83 m (Tue) You are standing 10 m from a tree. If you look up at an angle of 44.5° you see the top of the tree. How tall is the tree?

5. (Wed) If you drive your car with an average velocity of 48.0 km/hr to the east, how long will it take you to drive 144 km on a straight highway? (5 min / 5 pts)

6. v = Δx/Δt 48.0 km/hr = 144 km/Δt Δt = 3.0 hrs +1 Just ‘cause Δt = 144 km / 48.0 km/hr (Wed) If you drive your car with an average velocity of 48.0 km/hr to the east, how long will it take you to drive 144 km on a straight highway? (5 min / 5 pts)

7. (Thu) If you were to travel northeast (45°) for 22.3 km and then traveled south (180°) for 15.3 km, how far would you be from where you started and in what direction? (10 min / 10 pts)

8. x = length(cosθ) (Thu) If you were to travel northeast (45°) for 22.3 km and then traveled south (180°) for 15.3 km, how far (& direction) would you be from where you started?

9. (Fri) Take this time for some last minute review before the test.
