Answer:
Odd, odd, odd, even
Step-by-step explanation:
But I'm not sure from all answers. I hope my answer help you.
Exact Surface Area = 378pi
Approximate Surface Area = 1186.92
The approximate surface area uses pi = 3.14
The units are cm^2 or "square cm".
=========================================================
Work Shown:
SA = surface area of cylinder
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*pi*7^2 + 2*pi*7*20
SA = 2*pi*49 + 2*pi*140
SA = 2*49*pi + 2*140*pi
SA = 98pi + 280pi
SA = 378pi ..... exact surface area
SA = 378*3.14
SA = 1186.92 ..... approximate surface area

Side note: The diameter 14 cuts in half to get the radius r = 7
Answer:
45.29 miles per hour
Step-by-step explanation:
Speed is the distance over time. To find the average rate of speed for a trip, we simply need to take the total distance divided by the total time.
Avg. Speed = (188 miles + 197 miles) / (4 hours + 4.5 hours)
Avg. Speed = 45.29 miles per hour
Hence the average rate of speed for the trip was 45.29 miles per hour.
Cheers.

Answer:
Here's what I get
Step-by-step explanation:
Assume the function is a parabola.
The function has a maximum, so the parabola opens downward.
The maximum is at (-4,2), so the maximum is in the second quadrant.
The figure may look like the diagram below.
This is kind of a trick question.
Translation is moving an object a certain distance. The original object and its translation have the same shape and size.
Answer: B ) Angle A´ = 110°
