At around 20'000ft. and higher.
Answer:
3 3/4
Step-by-step explanation:
Add the two numbers:
3 + 3/4 = 3 3/4
3 3/4 is the amount walked in all.

The initial velocity is -150m/s.
Remember that:
V(t) = Vi + at, where v(t) is velocity at time t, Vi is initial velocity, and a is acceleration.
We know that the vehicle stopped after 30 seconds, so V(30) = 0.
Let's plug the useful info into our function and solve for a:
0 = -150 + a*30 Add 150 to both sides
150 = 30a Divide both sides by 30
a = 5 m/s²
The average acceleration is 5 meters per second squared.
Answer:Multiply using the FOIL method, then combine the real and imaginary parts of the expression.

28+3i
Step-by-step explanation:
Given that the octagon rotates 360 degrees, it is a given that for every regular division of the polygon (360/8 = 45 degrees), the image would coincide with the pre-image during the rotation. Therefore, the octagon would coincide a total of 8 times as it rotates 360 degrees about its center.
