Y=4x-18 is the parallel equation
Y=mx+b Substitute
2=4(5)+b Multiply by 5
2=20+b Substract 20 in both sides
-18=b
Tom did not break the 70mph speed limit of M1.
To know if Tom breaks the <em>speed limit </em>of the M1, we must first calculate Tom's speed and compare it to M1's speed limit.
Using the formula below,
- s = d/t............... Equation 1
Where:
- s = Tom's speed
- d = distance from Leicester to London
- t = time taken to travel from Leicester to London
From the question,
Given:
- d = 143 miles
- t = 8:25 to 10:15 = 2 hours 10 munites = (2+10/60) = (2+0.17)
- t = 2.17 hours.
Substitute these values into equation 1
- s = 143/2.17
- s = 65.899 mph.
Hence, Since Tom's speed is less than the M1 speed limit, Tom did not break the 70mph speed limit of M1.

Answer:
Step-by-step explanation:
Required
The positive root of 
Equate to 0
So, we have our function to be:
Differentiate the above function:
Using Newton's method of approximation, we have:
Plot the graph of to get 
--- see attachment for graph
From the attached graph, the first value of x is at 2.2; so:
So, we have:
The process will be repeated until the digit in the 6th decimal place remains unchanged
Hence:
