Step-by-step explanation:
Let c be any element of C. (I'm not sure wether you have to assume that C is non-empt or not)
C is a subset of B. That means that as c is in C, it is also in B. ()
Now, B is a subset of A. It follows that as .
That means c is an element of A. The predicate Q is true for all elements of A, including c.
Because we let c be any element of C, we have proven that the predicate Q is true for all elements in C.
Answer:
If c is a zero of a polynomial, then by the remainder theorem, x-c is a factor of the polynomial. Since our polynomial has zeros at -7, 4, and 6, we can write it as (x+7)(x-4)(x-6). Foiling the first two factors, we get (x^2 + 3x - 28)(x - 6). Distributing again, we get X^3 + 3x^2 - 28x - 6x^2 - 18x + 168. Finally, combining like terms gives us:
x^3 - 3x^2 - 46x + 168, which has degree 3 and a coefficient of 1 on X^3, so we are done.

Answer
Part A
None of the expressions given is the answer. The answer is w=V/(l*h)
PART B
w=8cm
Step-by-step explanation:
Part A
From the formula given to calculate the volume, we have to isolate the with w:
PART B
We know the formula to calculate with from Part A. Next, we replace given values in the formula.
w=V/(l*h)
w=120/(5*3)
w=120/15
w=8 cm
Answer:
Y = 21 [Small number].
X = 32 [Big number].
Step-by-step explanation:
First you have to order the set of values:
1, 1, 1, 2, 3, 3, 5, 7, 8, 8, 9
Now you just have to look for the middle value, which is 3.
Therefore your final answer is 3 :)
