Suppose that the functions u and w are defined as follows.
jasenka [17]

Answer(there are assumptions for this answer that you need to confirm and look at):

Assumptions: u(x)=x^2+3 and w(x)=\sqrt{x+2}

Answer if the operation is multiplication:

If you meant a closed dot which is the symbol for multiplication.

(u \cdot w)(2)=14

(w \cdot u)(2)=14

Answer if the operation is composition:

If you meant an open dot which is the symbol for composition.

(u \circ w)(2)=7

(w \circ u)(2)=3

Note: I don't know if you actually meant w(x)=\sqrt{x+2} or if w(x)=\sqrt{x}+2. Please let me know one way or the other.

Step-by-step explanation:

If we assume the functions are:

u(x)=x^2+3

w(x)=\sqrt{x+2}

u \cdot w=w \cdot u since multiplication is commutative.

u(2)=2^2+3

u(2)=4+3

u(2)=7

w(2)=\sqrt{2+2}

w(2)=\sqrt{4}

w(2)=2

We are asked to find (u \cdot w)(2) and (w \cdot u)(2).

The order doesn't matter in multiplication.

(u \cdot w)(2)

u(2) \cdot w(2)

7 \cdot 2

14

(w \cdot u)(2)

w(2) \cdot u(2)

2 \cdot 7

14

Now you might have meant composition which symbolized with an open circle, not a closed one.

(u \circ w)(2)

u(w(2))

u(2) since w(2)=2

2^2+3

4+3

7

(w \circ u)(2)

w(u(2))

w(7) since u(2)=7

\sqrt{7+2}

\sqrt{9}

Another 6th grade problem! (:
nata0808 [166]

Answer: There are <u>4</u> teams in the league

Step-by-step explanation:

(1) Add 14 four times: 14+14+14+14 = 56

(2) Multiply 14 four times: 14 x 4 = 56

(3) Combine both of these numbers into the <em>t  </em>factor: 14t = 56

(4) Divide both sides by 14 and simplify: (14t / 14) = 56/14 | t = <u>4</u> (simplified)

Rp+s=t in terms of r, s,and t
expeople1 [14]

Answer:

p=(t-s)/r

Step-by-step explanation:

This is an equation so all we have to do is solve backwards step by step:

rp+s=t

rp+s-s=t-s

rp/r=(t-s)/r

p=(t-s)/r
