Answer:
59
Step-by-step explanation:
5: 30 pm is 2.5 hours after 3 : 00 pm
Substitute x = 2.5 into the equation
y = - 6.2(2.5)² + 41.5(2.5) - 5.6
= - 38.75 + 103.75 - 5.6
= 59.4
The average number of cars is 59
To make the second gear aligned with the first it would have to rotate 5 times, a total of 120 seconds and/or 2 minutes will pass
So the answer is I.
Answer: 
Step-by-step explanation:
You know that "Z" is the midpoint of "YA". This means the following:

Now, you know that the expression for "YZ" is:

And the given expression for "ZA" is:

Knowing these expressions, you can substitute them into
, as following:

Finally, you must add these expressions in order to get "YA".
Therefore, this is:
