Required potynomial = (x -5)(x - 3 - 2i)(x - 3 + 2i) = (x - 5)(x^2 - 6x + 13) = x^3 - 6x^2 + 13x - 5x^2 + 30x - 65 = x^3 - 11x^2 + 43x - 65
        
             
        
        
        
Answer:
 is an odd function.
 is an odd function.
Step-by-step explanation:
We are asked to prove whether  is even or odd.
 is even or odd. 
We know that a function  is even if
 is even if  and a function
 and a function  is odd, when
 is odd, when  .
.
We also know that an even function is symmetric with respect to y-axis and an odd function is symmetric about the origin.
Upon looking at our attachment, we can see that  is symmetric with respect to origin, therefore,
 is symmetric with respect to origin, therefore,  is an odd function.
 is an odd function.

Answer:
90
Step-by-step explanation:
it is 90 because in the first slot there can be any 10 numbers and in the second slot the set can contain any of the remaining 9 numbers and then we can multiply these two numbers together to find the total amount of sets.

Answer:
Step-by-step explanation:
A+B+C = 180°
A ≤ B ≤ C
B = A+9
C = 3A+26
A+B+C = A + (A+9) + (3A+26) = 5A + 35° = 180°
5A = 145°
A = 29°
B = A+9 = 38°
C = 3A+26 = 113°
