### Transcript of "8.5 Bingo"

1. 1. 8.5 Bingo!<br />By: Cindel, Sarah, Lucas, Aleks, Quinn and Olivia<br />
2. 2. An equation that models sound intensity is<br />dependent on what two variables? <br />a)    time and altitude<br />b)    frequency and wavelength<br />c)    time and frequency<br />d)    wavelength and amplitude<br />
3. 3. Notes sound good together if their combined waveform is: <br />a)    Regular and repeating<br />b)    Irregular and random <br />
4. 4. The height versus time equation of a skier moving down a hill is shown below.<br />120(0.5^(0.1*x))+2*sin(x)<br />What two types of functions could be combined to create this graph? <br />
5. 5.     Which of the following situations would not be best represented by a combined function:<br />a)    path of a bungee jumperb)    acceleration of a falling object due to gravityc)    a predator-prey relationshipd)    motion of interfering waves<br />
6. 6. Let f(x)=(x2), let g(x)=(x+6).<br />Using this information, determine the composite function of y=f(g(x))<br />
7. 7. If you combine these graphs what would the resultant graph look like?<br />
8. 8. Which musical note has the higher frequency: C or C#?<br />   <br />
9. 9. When modelling combined functions, you need a minimum of 1 or 2 or 3 or 4 functions?<br />
10. 10. (x+1)2/ x 2 +3x+4 can be simplified to:<br />a) (x+1) / (x+3)<br />b) (x+1) / (x+2) <br />c) (x+3) / (x+1) <br />d) (x+2) / (x+3)<br />
11. 11. If f(x)=x+4 and g(x)=x2+1, then f(x)+g(x)=? <br />a) x 2 +x+5<br />b) x+5 <br />c) x 2 +3<br />d) 2x+5<br />e) x 2 +x+7 <br />
12. 12. If your heart rate usually looks like this:<br /> Explain what would happen if you got<br /> scared: <br /> a)the frequency would increase and the heart beats would get closer together <br />b)the frequency would decrease and the heart beats would get farther apart <br />c)the maximums would get higher and the minimums would get lower <br />d)it would not make as periodic a function <br />
