Answer:
Step-by-step explanation:
First let us write the given polynomial as in descending powers of x with 0 coefficients for missing items
F(x) = x^3-3x^2+0x+0
We have to divide this by x-2
Leading terms in the dividend and divisor are
x^3  and x
Hence quotient I term would be x^3/x=x^2
                                                    x-2) x^3-3x^2+0x+0(x^2
x^3-2x^2
Multiply x-2 by x square and write below the term and subtract
We get  
                                                    x-2) x^3-3x^2+0x+0(x^2
x^3-2x^2
                                                          ---------------
-x^2+0x
Again take the leading terms and find quotient is –x
                                                 x-2) x^3-3x^2+0x+0(x^2-x
x^3-2x^2
                                                          ---------------
-x^2+0x
                                                                   -x^2-2x
Subtract to get 2x +0 as remainder.
                                                   x-2) x^3-3x^2+0x+0(x^2-x-2
x^3-2x^2
                                                          ---------------
-x^2+0x
                                                                   -x^2+2x
                                                           -------------
                                                                       -2x-0
                                                                               -2x+4
                                                              ------------------
                                                                                -4
Thus remainder is -4 and quotient is x^2-x-2
 
        
                    
             
        
        
        
Answer:
9
Step-by-step explanation:
you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.
So we would need to realize that the constant would be equal to (-6/2)^2  =(-3)^2 = 9
We have completed the square.
f(x) = 4*( x - 3)^2  + 20   is now in Vertex Form
 
        
             
        
        
        
Answer:
18.84cm
Step-by-step explanation:
There is a formula which for the diameter is pie (3.14) times the diameter. Now if you have the radius it would be pie (3.14) times 2 times whatever the radius would be. Now you could use either formula for this, just divide the diameter by two to get 3. 
So 3x2x3.14=18.84cm
So then you could just multiply 6x3.14 and still get 18.84cm

Answer:
= 40°
Step-by-step explanation:
180-115=65°
65+75=140°
180-140=40°
=40°
