Answer:

<h2>A. F(x)=2x^{9} -4x^{2} +4</h2>

Step-by-step explanation:

First of all, par and odd functions have their graphic particularities.

Specificially, if the grade of the polynomial is pair, then the function has a symmetric graph, the curve will have a returning point, like the parabola. On the other and, if the grade of the polynomial is odd, then the graph of the function won't have an symmetry like pair ones, and it won't have a returning points like parabolas

So, in this case, the raph doesn't have a returning point like a parabola or an U movement, that means possible answers are A and B.

Choice B cannot be the answer because the negative sign in the first term indicates a reflection accros the vertical axis, and the graph is showing an original function.

Therefore, the right answer is A. F(x)=2x^{9} -4x^{2} +4

A, since the graph is not in a "U" shape aka parabola the degree cant be 2 so C is wrong and B and D are negative fuctions while the graph is showing one that is positive.

A cylinder vase has a height of 10 inches and a diameter of 3 inches. If the water raises to 9/10 of the way to the top, approxi
goblinko [34]

Answer:

The volume of water in the vase is 64 in^3

Step-by-step explanation:

A cylinder vase has a height, h, of 10 inches and its diameter of 3 inches. This means that its radius, r, is:

r = 3 / 2 = 1.5 inches

To find the volume of the water in the vase if the water raises to 9/10 of the way to the top, we first have to find the volume of the vase when it is filled with water and then, find 9/10 of that volume.

The volume of a cylinder is given as:

V = \pi r^2h

The volume of the vase will be:

V = \pi * 1.5^2 * 10\\V = 70.69 in^3

Hence, the volume of the water in the vase when it is 9/10 filled is:

\frac{9}{10} * 70.69 = 63.62 in^3

Approximating to the nearest cubic inch, the volume of water in the vase is 64 in^3

-4x-15y=-17<br>-x+5y=-13<br><img src="https://tex.z-dn.net/?f=%20-%204x%20-%2015y%20%3D%20%20-%2017%20%20%5C%5C%20%20-%20x%20%2B

To solve this system of linear equations we need a little trick called elimination steps are below

we are given the following system of equations
- 4x - 15y = - 17
- x + 5y = - 13
if you look at the x variables in both equations you can see that we can easily eliminate them by multiplying the bottom equation by -4 as so
- 4x - 15y = - 17
- 4( - x + 5y = - 13)
simplify and we get
- 4x - 15y = - 17
4x - 20y = 52
now we can combine like terms on each side with the x's cancelling and get

- 35y = 35
now divide off -35
y = - 1
great now we can go back to our original system and pick a equation and substitute y back in to find x lets use

- x + 5y = 13
so now we substitute y and get
- x + 5( - 1) = 13
- x - 5 = 13
- x = 17
x = - 17

now we put x and y into one coordinate (x,y)
so now our FINAL ANSWER IS
(-17,-1)

State the domain and range and determine if it's a function?<br> Domain:<br> Range:<br> Function?
kramer

Step-by-step explanation: Let's first write the coordinates of each point.

When finding the coordinates of a

given point, be very careful with your signs.

On the x-axis, left means negative and right means positive

and on the y-axis, down means negative and up means positive.

The points in this problem are (-1, -2), (4, -2), (1, 1), (2, 3).

The domain is the set of all x-coordinates.

So here, the domain or D = {-1, 4, 1, 2}.

The range is the set of all y-coordinates.

So here, the range is {-2, 1, 3}.

Notice that I only listed the 1 once.

We only need to mention it once in our range.

Finally, let's determine if it' a function.

If none of the x-coordinates repeat, it's a function.

Since none of them do repeat, it's a function.
