Athe answer is -2 because it is behind the 0 and will be negative and it is two lines away from the 0 so the answer is -2
Using it's concepts, the average speed and the average velocity are given as follows:
- Average speed: 40 miles per hour.
- Average velocity: 0 miles per hour.
<h3>Average speed</h3>
The average speed is given by the quotient between the total distance traveled and the time taken, that is:
Average speed = total distance/time
In this problem, the total distance is of 60 miles(30 miles west + 30 miles south), in a time of 1.5 hours(1 hour west and 0.5 hours south), hence the average speed is given as follows:
Average speed = 60/1.5 = 40 miles per hour.
<h3>Average velocity</h3>
The average velocity is given by the quotient between the displacement and the time taken, that is:
Average velocity = displacement/time
The displacement is the difference between the final position and the initial position. Since the person got back to the start, finish = start, hence the displacement is of zero, as is the average velocity.

Answer:
122.67 or round it to 123
Step-by-step explanation:
i used the butterfly method.
92/75 = x/100.
i multiplied 92*100=9200
then i divided it with 75.
9200/75=x
so the answer is
x=122 or 123

Answer:
Part a) The equation for the volume of the film canister is
Part b) The radius of the film canister is 
Step-by-step explanation:
<u><em>The complete question is</em></u>
A film canister in the shape of a cylinder has a height of 8 centimeters and a volume of 32π cubic centimeters.
a. Write an equation for the volume of the film canister.
b. What is the radius of the film canister?
Part a) Write an equation for the volume of the film canister
we know that
The volume of a cylinder is equal to
where
r is the radius of the circular base
h is the height of the cylinder
we have
substitute
----> equation for the volume of the film canister
Part b) What is the radius of the film canister?
we have
Simplify
Divide by 8π both sides
square root both sides
