1. A polar bear walk 2 miles North, then 4 mi East, then 4 mi West, then 3 mi South. The bear completes his trip in 4 hours. a) Sketch the motion of the bear. Clearly label positions (number and units) and directions throughout the bear’s trip. Also, label displacement vectors with magnitudes during the bear’s trip. b) What is the bear’s total distance traveled? c) What is the bear’s total displacement? (Include magnitude and direction.) d) Draw the displacement vector for the entire trip below. Label magnitude and show direction. e) What is the bear’s average speed during the trip? f) What is the bear’s average velocity during the trip? (Include magnitude and direction.)

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

is there a question here?

step-by-step explanation:

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
