Answer:
The unicycle will travel 351.68 inches in 7 revolutions
Step-by-step explanation:
The circular shape moves a distance equal to its circumference in each revolution, then the rule of the distance of the circular shape travels n turns is D = π d n, where
- d is the diameter of the circular shape
- n the number of revolution
∵ A unicycle wheel has a diameter of 16 inches
∴ d = 16 inches
∵ The unicycle will travel 7 revolutions
∴ n = 7
→ Substitute them in the rule of the distance above
∵ D = π(16)(7)
∵ π = 3.14
∴ D = 3.14(16)(7)
∴ D = 351.68 inches
→ No need to round it, it is in the hundredth of an inch
∴ The unicycle will travel 351.68 inches in 7 revolutions
6% of $22 = 1.32
22 + 1.32 = 23.32 (cost of meal with tax)
20% of 23.32 = 4.66
23.32 + 4.66 = 27.98
Total cost = $27.98
Plug in the 5 values in the domain
f(-2) = 2(-2)^2 - 2(-2) + 5 = 8+4+5 = 17 so first number in the range is 17.
f(-1) = 2(-1)^2 -2(-1) + 5 = 2 + 2 + 5 = 9
f(0) = 0 - 2 + 5 = 5
fond f(1) and f(2) in the same way
results are 17,9,5,5,9
so the range is {5, 9,17} (you don't repeat values)
