Answer:
I'm sorry, I'm not really certain of anything except part A
Step-by-step explanation:
Part A
First of all write the function.
Let x = the number of hours traveled. The y intercept is the value when x = 0
y = 2x + 50 Every 1 hour, the speed increases by 2 mph
(1) The y intercept is 0,50
(2) The car was travelling at 50 mph to begin with.
Part B
Average speed = total distance covered / time interval
Distance between 1 and 2 = 52 + (54 - 52)/1 = 54
Distance between 2 and 3 = 54 + (56 - 54)/1 = 56
Average = (54 + 56)/2 = 55
Part C
I don't see how Part C has any answer. It must change motion even if it winds up where it started from (in which case the velocity cannot be both 60 and 0 at the same time)
I think they want you to answer 0.
Answer:
f=3
Step-by-step explanation:
The intervals means that angle f is between the quadrant 1.
Using that, we can use this identity
where x+y=90
Sorry that really confusing but i like your hand writing you did a really good job
