Given:

The polynomials are:

$3x^2y^2-2xy^5$

$-3x^2y^2+3x^2y^2+3x^4y$

To find:

The completely simplified sum of the polynomials.

Solution:

We have,

$3x^2y^2-2xy^5$

$-3x^2y^2+3x^2y^2+3x^4y$

The sum of given polynomials is:

$Sum=3x^2y^2-2xy^5-3x^2y^2+3x^2y^2+3x^4y$

$Sum=-2xy^5+3x^4y+3x^2y^2$

Therefore, the sum of the given polynomials is $-2xy^5+3x^4y+3x^2y^2$ . It is a polynomial with degree 6 and leading coefficient -2.

Step-by-step explanation:

Remark

The way this is worded, it sounds like it is a horizontal distance. However by the marking it looks like they want the hypotenuse. Life can be very confusing sometimes.

The angle of the triangle that you need to know is the one on the right. The line of sight line is parallel to the base of the triangle. So the angle on the right is 8 degrees by the Z theorem.

Solution

Sin(8) = 1817 / x Multiply both sides by x

x*sin(8) = 1817 Divide by sin(8)

x = 1817/sin(8)

sin(8) = 0.1392

x = 1817/0.1392

x = 13055.7

Note

Watch how you do this. I would put it into your calculator as

1817

sin(8)

If you use the rounded answer I gave for sin(8), you might get it wrong. This is a big distance and you should just use the exact number you get for sin(8).

I added a picture with it for you. I suggest that before this becomes an issue you take some time and study box and whisker plots, because they tend to show up on a lot of standardized math tests.

In the figure shown, line AB is parallel to line CD. Part A: What is the measure of angle x? Show your work. (5 points)

gtnhenbr [62]

a) ∠PQR=65° (alternate interior angles theorem)

∠PRQ = 60° (linear pair)

x = 55° (angles in a triangle add to 180°)

b) ∠APQ and ∠PQR are congruent alternate interior angles.

Select the rational expression that is equivalent to the given expression below. 4 over x - 3

Ad libitum [116K]

When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number: $\frac{1}{3}$ . in our rational number the denominator is 1, and the numerator is 3

Now, a rational expression is an algebraic expression in a rational for. If we apply the same to your problem. 4 over x-3 means 4 divided by x-3, or in mathematical notation: $\frac{4}{x-3}$ . In this case, the numerator is 4, and the denominator is $x-3$ .

We can conclude that the equivalent rational expression of <span>4 over x - 3 is </span> $\frac{4}{x-3}$ .

I need help with #1 10 points

Vikentia [17]

Answer:

No it is not proportional

Step-by-step explanation:

You cant multiply each of the inputs by a constant number to get the output.

There is only 2 of them that you can, but the other 2 no. And you want he whole table so you need all of the inputs not just some. So no, its not proportional.

Hope this helped!
