Answer:
Step-by-step explanation:
1. Use this
to find the average rate of change
2. Average rate of change = 
3.
and
(To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))
4. Replace -4 to f(8) and -10 to f(6)
5. So it will look like
6. Solve
Answer:
start with root and minus with 3 and 8 and answer the following
The speed of the driver is 200km/hr.
<h3>How to calculate the speed?</h3>
The information is incomplete and an overview will be given since the complete information wasn't found online.
It should be noted that speed is calculated as:
= Distance / Time
Let distance = 2000km
Let time = 10 hours.
Speed = Distance/Time
Speed = 2000/10
Speed = 200km/hr

Write both sides as powers of 8, then simplify:





However, on the left hand side, this would mean we'd have,
, which is undefined (assuming the real-valued logarithm), so this equation has no real solution.
