Card 5 / 6:
Division Algorithm
given a polynomial dividend f ( x ) and a nonzero polynomial divisor d ( x ) where the degree of d ( x ) is less than or equal to the degree of f ( x ) , there exist unique polynomials q ( x ) and r ( x ) such that f ( x ) = d ( x ) q ( x ) + r ( x ) where q ( x ) is the quotient and r ( x ) is the remainder. The remainder is either equal to zero or has degree strictly less than d ( x ) .

What kind of answer is that😑?

I had just woken up when i got this message

Can you please help me. Tomorrow is the deadline of my assignment then I don't know how to solve that

how do you find the real and complex roots of a polynomial?
Abdul
@abdul with delta maybe which is b(square)4ac=result then the 1st root bradical delta over 2a and the 2nd root b+radical delta over 2a. I am not sure if this was your question but check it up
Nare
This is the actual question: Find all roots(real and complex) of the polynomial f(x)=6x^3 + x^2  4x + 1
Abdul
@Nare please let me know if you can solve it.
Abdul

The average annual population increase of a pack of wolves is 25.
how do you find the period of a sine graph
Period =2π
if there is a coefficient (b), just divide the coefficient by 2π to get the new period
Am
if not then how would I find it from a graph
Imani
by looking at the graph, find the distance between two consecutive maximum points (the highest points of the wave). so if the top of one wave is at point A (1,2) and the next top of the wave is at point B (6,2), then the period is 5, the difference of the xcoordinates.
Am
you could also do it with two consecutive minimum points or xintercepts
Am
I will try that thank u

A cell phone company offers two plans for minutes. Plan A: $15 per month and $2 for every 300 texts. Plan B: $25 per month and $0.50 for every 100 texts. How many texts would you need to send per month for plan B to save you money?
For Plan A to reach $27/month to surpass Plan B's $26.50 monthly payment, you'll need 3,000 texts which will cost an additional $10.00. So, for the amount of texts you need to send would need to range between 1100 texts for the 100th increment, times that by 3 for the additional amount of texts...

...for one text payment for 300 for Plan A. So, that means Plan A; in my opinion is for people with text messaging abilities that their fingers burn the monitor for the cell phone. While Plan B would be for loners that doesn't need their fingers to due the talking; but those texts mean more then...

Hey I am new to precalculus, and wanted clarification please on what sine is as I am floored by the terms in this app? I don't mean to sound stupid but I have only completed up to college algebra.
I don't know if you are looking for a deeper answer or not, but the sine of an angle in a right triangle is the length of the opposite side to the angle in question divided by the length of the hypotenuse of said triangle.
Marco
can you give me sir tips to quickly understand precalculus. Im new too in that topic.
Thanks
Jenica
if you remember sine, cosine, and tangent from geometry, all the relationships are the same but they use x y and r instead (x is adjacent, y is opposite, and r is hypotenuse).
Natalie
it is better to use unit circle than triangle .triangle is only used for acute angles but you can begin with. Download any application named"unit circle" you find in it all you need. unit circle is a circle centred at origine (0;0) with radius r= 1.

What is domain
johnphilip
the standard equation
of the ellipse that has vertices (0,4)&(0,4) and foci (0, 15)&(0,15)
it's standard equation is x^2 + y^2/16 =1
tell my why is it only x^2? why is there no a^2?
This term is plural for a focus, it is used for conic sections. For more detail or other math questions. I recommend researching on "Khan academy" or watching "The Organic Chemistry Tutor" YouTube channel.
