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:
Answer:
$173.90
Step-by-step explanation:
The most obvious way to answer this question is to multiply $9.40 by 18.5
This would result in 173.90.
But I realize nobody like to deal with decimals in a multiplication problem, so here's the way I would do it (<em>especially if you don't have a calculator!</em>)
The strategy is to break it down!
Multiply $9.40 x 18 hours to start, since this is easier.
So, that's $169.20 for 18 hours of work.
We aren't finished, because Abdel worked for 18.5 hours.
So, what half of $9.40?
= 4.7
-or-
$4.70
So, knowing that Abdel makes $4.70 in half an hour, lets just add that onto the $169.20 we got earlier.
169.2 + 4.7 = 173.9
-or-
$173.90 for 18.5 hours of work!
