Answer:
2x + 3.
Step-by-step explanation:
x + x + 3
= 2x + 3.
Answer:
Pretend the y-axis is a mirror
If the original shape is
P=4,-2
Z=5,-4
M=4,-4
The new image made by mirroring it will be
P’= -4,-2
Z’= -5,-4
M’= -4,-4
Step-by-step explanation:
Sorry if this doesn’t make sense, just graph P’, Z’, and M’ for a mirrored image
The chance is 50% because if there are 2 children the probability would be 1/2 or 50%.
√(1/121) = √1 / √121 = 1 / 11 = <em>11⁻¹</em>
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
