Since the opposite side of the needed value is 90°, the side that contains x is also 90°. So you would have to subtract 29 from 90 to get x
Answer:
Step-by-step explanation:
The
average rate of change
of f(x) over an interval between 2 points (a ,f(a)) and (b ,f(b)) is the slope of the
secant line
connecting the 2 points.
To calculate the average rate of change between the 2 points use.

This means that the average of all the slopes of lines tangent to the graph of f(x) between (4 ,0) and (9 ,35) is 7.
I think the answer is 0-1, but i will have to see the answers to determine.
Hope it helps!
