Step-by-step explanation:
(a)
Using the definition given from the problem
Therefore it is true for intersection. Now for union, we have that
Therefore, for this case, it would be true that .
(b)
1 is not a set.
(c)
To begin with
Therefore
Now, given an element of it will belong to both sets, therefore it also belongs to , and you would have that
, therefore .
(d)
To begin with , therefore
Answer:
c
Step-by-step explanation:
im not completely sure
Solution:
we have been asked to verify that -5, 1/2, and 3/4 are the zeroes of the cubic polynomial
To verify that whether the given values are zeros or not we will substitute the values in the given Polynomial, if it will returns zero, it mean that value is Zero of the polynomial. But if it return any thing other than zeros it mean that value is not the zero of the polynomial.
Let
Hence -5, 1/2, and 3/4 are not the zeroes of the given Polynomial.
Since sum of roots
But
Hence we do not find any relation between the coefficients and zeros.
Anyway if the given values doesn't represents the zeros then those given values will not have any relation with the coefficients of the p[polynomial.
Answer:
The coordinates of B is (5,-2)
Step-by-step explanation:
In order to find the coordinates of B, you have to use midpoint formula. Then substitute the following values into the formula :
Let (x1,y1) be A (-3,-6),
Let (x2,y2) be B,
Let midpoint be M (1,-4),
