The average acceleration of an object is calculated as the final speed minus the initial speed divided by the elapsed time.
So:
Where
= final speed
= initial speed
= elapsed time.
Thus:
The acceleration of the cyclist is:
a = 2.667
The acceleration of the car is:
a = 3.75 
The average acceleration of the car is higher than the average acceleration of the cyclist.
<E = 180 - 14 - 45 = 121
so
<D = 180 - 27 - 121 = 32
answer
<D = 32
Answer: 
{
}
Step-by-step explanation:
We know that, by definition, the Domain is the set of all the x-coordinates of the ordered pairs and the Range is the set of all the y-coordinates of the ordered pairs.
Therefore, given 
, you can observe that the set of all second elements of ordered pairs (the values of "y") is the following:
{
}
Therefore, we can conclude that if , then the range is:
{}
Answer:
35 feet
Step-by-step explanation:
We'll begin by calculating the resultant for you and your friend.
For you:
R² = 12² + 9²
R² = 144 + 81
R² = 225
Take the square root of both side
R = √225
R = 15 feet
For your friend:
R² = 16² + 12²
R² = 256 + 144
R² = 400
Take the square root of both side
R = √400
R = 20 feet
Finally, we shall determine the distance between you and your friend.
The distance between you and your friend is obtained by adding your resultant and that of your friend together i.e
You resultant = 15 feet
Your friend's resultant = 20 feet
Distance between you and your friend = 15 + 20 = 35 feet.
Therefore, you threw the baseball 35 feet away from your friend.
