Answer:
Make use of your knowledge of the maximum and minimum of the cosine function. Then scale and translate according to the way that function is scaled and translated to make f(x).
Step-by-step explanation:
f(x) is the cosine function, multplied by 4 and with 9 added to the result.
The minimum of the cosine function is -1. Multiplying that by 4 gives -4, and adding 9 gives 5.
The maximum of the cosine function is +1. Multiplying that by 4 gives +4, and adding 9 gives 13.
The minimum and maximum of f(x) are 5 and 13, respectively.
The equation which relates speed, V and time, t to the total distance traveled is 70 = Vt
- 70 = Vt
- v(5) = 14
- V(7) = 10
- V(3.5) = 20
Since he is traveling at a constant speed, the relationship between, V and t can be written thus :
- Distance = speed × time
- 70 = Vt
<u>At time, t = 5 </u>
<u>At time, t = 7 </u>
<u>At time, t = 3.5</u>
Therefore, the relationship between V and t with distance is 70 = Vt
