Answer:
Coefficient
Step-by-step explanation:
-Usually a combination of variables and constants are multiplied to get a product.
-The constant or number part in the multiplication process is called the Coefficient
The answer is: [D]: " <span>(1, 0, 0), (0, –2, 0), (0, 0, 6) " .

Well this is simple a calculator type problem...but if you are curious as the the algorithm used by simple calculators and such...
They use a Newtonian approximation until it surpasses the precision level of the calculator or computer program..
A newtonian approximation is an interative process that gets closer and closer to the actual answer to any mathematical problem...it is of the form:
x-(f(x)/(df/dx))
In a square root problem you wish to know:
x=√n where x is the root and n is the number
x^2=n
x^2-n=0
So f(x)=x^2-n and df/dx=2x so using the definition of the newton approximation you have:
x-((x^2-n)/(2x)) which simplifies further to:
(2x^2-x^2+n)/(2x)
(x^2+n)/(2x), where you can choose any starting value of x that you desire (though convergence to an exact (if possible) solution will be swifter the closer xi is to the actual value x)
In this case the number, n=95.54, so a decent starting value for x would be 10.
Using this initial x in (x^2+95.54)/(2x) will result in the following iterative sequence of x.
10, 9.777, 9.774457, 9.7744565, 9.7744565066299210578124802523397
The calculator result for my calc is: 9.7744565066299210578124802523381
So you see how accurate the newton method is in just a few iterations. :P
Answer:
$57.44
Step-by-step explanation:
1. subtract 15% from the bill with coupon:
$56.32 - ($56.32 x 0.15) = $47.87
2. add 20% to this new bill:
$47.87+(47.87 x 0.20) = $57.44
Answer:
125g
Step-by-step explanation:
You can find the mass of the yoghurt by dividing the mass of the fruit and the yoghurt by the sum of the ratio,(2+5), then multiplying that value by 5.
