Answer:

Step-by-step explanation:
f=v+at
It requires you to make a the subject of the formula
f-v=at
Dividing both sides by t then

Therefore, the equivalent for a is 
Answer: First option.
Step-by-step explanation:
You can idenfity in the figure that
is formed by two secants that intersect outside of the given circle.
It is important to remember that, by definition:

Knowing this, you can set up the following equation:

Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle
.
This is:

First, we can simplify the left side. (6+8x)/2 is equal to 3 + 4x. We can put the equation together at this point.
3 + 4x = 5x
we can subtract 4x from both sides to get our final answer,
3 = x, or x = 3. :)
9mph because 20 minutes time 3 is one hour so multiply 3 by 3 to get 9
