9514 1404 393
Answer:
- vertex: 171°
- central: 9°
- exterior: 9°
Step-by-step explanation:
The central angle is equal to the exterior angle:
360°/n = 360°/42 = 8 4/7° ≈ 9°
The vertex angle is the supplement of this:
180° -8 4/7° = 171 3/7° ≈ 171°
Answer:
72
Step-by-step explanation:
6(4(6)-3)-9(6)
6×(24−3)−54
I think the answer is 72, sorry if it is wrong
The average rate of change from x=8 to x=5 can be calculated as:
f(8) = 0
f(5) = 4
Using the values we get:
So, first option gives the correct average rate of change from x=8 to x =5 for the given function.
7/8 miles = 49 / 56 miles so it will take the road crew 49 hours to repave the road.
