The domain of discourse is sets. Suppose some predicate Q is true for all elemenst of A: ∀a ∈ A Q(a). Recall the definition of s

Answer:

See the step-by-step explanation

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. ( $c \in C \Rightarrow c \in B$ )

Now, B is a subset of A. It follows that as $c \in B \Rightarrow c \in A$ .

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.

Hello, happy Friday, I am just here with some geometry questions.

Answer:

VW = 43.2

Step-by-step explanation:

First, we can see that VZ = 88 - 55 = 33.

Then by the Triangle Proportionality Theorem, we can write that:

$\displaystyle \frac{55}{33}=\frac{72}{VW}$

Simplify:

$\displaystyle \frac{5}{3}=\frac{72}{VW}$

Cross-multiply:

$216=5VW$

So:

$\displaystyle V=\frac{216}{5}=43.2$
