U = {r,s,t,u,v,w,x,y,z}
Mandarinka [93]

Answer:

{r,z}

Step-by-step explanation:

U = {r,s,t,u,v,w,x,y,z}

P = {s,t,u,v,w}

Q = {u,v,x,y}

P' means elements in the universe,U, that are not in P.

P'={r,x,y,z}.

Q' means elements in the universe,U, that are not in Q.

Q'={r,s,t,w,z}.

P' intersect Q' means what elements are in common in both lists.

{r,z}

How do you solve this
pickupchik [31]
Well, there is 4 times 6 so that's 24 and it says plus 3 times 4 so that is 12 so you add 24 plus 12 and that is 36

Shtirlitz [24]

Answer:

1) A

2) C

Step-by-step explanation:

Question 1)

We have the function:

y=2(x+2)^2-3

Notice that this is a quadratic function in the vertex form:

y=a(x-h)^2+k

Where (h, k) is the vertex point, a is the leading co-efficient, and h is also the axis of symmetry.

Let's identify these characteristics first. Our leading co-efficient a is 2.

And our vertex is (-2, -3). It is <em>not</em> (2, -3) because (x+2) is the same as (x-(-2)).

We want to find the minimum or maximum value of our function, as well as the domain and range.

First, by looking at our leading co-efficient, which is 2, we can see that it's positive. Therefore, our parabola curves upwards.

Therefore, we will have a <em>minimum</em> value. And this minimum value will be our vertex.

Our vertex is (-2, -3). Therefore, our <em>minimum</em> value is at y=-3.

The domain of all quadratics is always all real numbers.

For the range, we refer to our minimum/maximum value.

Our parabola curves upwards and our <em>minimum </em>value is at y=-3.

Therefore, our range is all numbers <em>greater than or equal to </em>-3.

The choice that represents all of these answers is A.

Question 2)

We have:

y=2(x+2)^2-4

Again, this is in vertex form. Let's identify our characteristics.

Our leading co-efficient a is 2, so the graph curves upwards.

And our vertex is at (-2, -4).

The axis of symmetry is the same as the x-coordinate of our vertex. Therefore, our axis of symmetry is at x=-2.

So, this function has a vertex at (-2, -4) and an axis of symmetry at x=-2.

The choice that represents these characteristics is C.

So, our answer is C.

And we're done!

Estimate the sum of 4.27 and 9.91 by first rounding each number to the nearest whole number.
mart [117]
4.27 + 9.91

Round them to the nearest whole number.

4.27 ⇒ 4
9.91 ⇒ 10

Now you can add them up.

4 + 10 = 14
