Let smaller number be x/2 and the larger number x.
x/2 + x = 81
x/2 + x = 3x/2
3x/2 = 81
3x = 162
x= 54
The smaller number is 54/2= 27 and the larger number is 54.
When the direction is reversed velocity = 0
v = ds/dt = 6t^2 - 42t + 60 = 0
t^2 - 7t + 10 = 0
(t - 5)(t - 2) = 0
t = 2 s and 5 s which are the times when the direction is reversed
Position at t = 2 = 2(2)^3 - 21(2)^2 +60(2) + 3 = 55 feet
at t = 5 position = 28 feet
Acceleration = dv/dt = 12t - 42
At t = 2 acceleration = -18 ft s-2
At t = 5 ............... = 18 ft s-2
Answer:
Pizza: 27°
Curry: 108°
Fish and Chips: 63°
Kabab: 27°
Other: 135°
Step-by-step explanation:
Frequency 40 = 360°
Pizza (3) = 
* 360° = 27°
Curry (12) = 
* 360° = 108°
Fish and Chips (7) = 
* 360° = 63°
Kabab (3) = * 360° = 27°
Other (15) = 
* 360° = 135°
27 + 108 + 63 + 27 + 135 = 360
