Answer:

Its A. 15x^4+13x^2y+2y^2

Answer:

I think its neither because

Step-by-step explanation:

Parallel lines and their slopes are easy. Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel. Perpendicular lines are a bit more complicated.

Answer:

perpendicular

Step-by-step explanation:

They form a 90 degree angle because one is vertical and the other is horizontal.

Answer:

Answer is 32 i have no idea why

Answer:

1. Angle f and s are supplementary angles, which is equal to 180, so we will: 180-35= 145

So angle f= 145 (degrees)

Angle Q= 180-49 (supplementary angles)

So angle Q= 131

I'm so sorry but I do not know the answer of Q2

Answer:  radius = 5.83 cm     height = 8.12 cm

Step-by-step explanation:

First, let's find the circumference of the 210° section of the circle.

[tex]C=2\pi r\bigg(\dfrac{\theta}{360^o}\bigg)\\\\\\C=2\pi(10)\bigg(\dfrac{210^o}{360^o}\bigg)\\\\\\C=\dfrac{35}{3}\pi[/tex]

The circumference of the the cone is [tex]\dfrac{35}{3}\pi[/tex] .  We can use this to find the radius .

[tex]C=2\pi r\\\\\dfrac{35}{3}\pi=2\pi r\\\\\\\dfrac{35\pi}{3\cdot 2\pi}=r\\\\\\\dfrac{35}{6}=r\\\\\\5.83=r[/tex]

When you fold the 210° section into a cone, the slant height is the original radius of 10.  We can use the radius and slant height of the cone to form a right triangle with the height.  Use the Pythagorean Theorem to find the height.

radius² + height² = slant height²

[tex]\dfrac{35}{6}^2\ +\ h^2=10^2\\\\\\.\qquad \quad h^2=10^2-\bigg(\dfrac{35}{6}\bigg)^2\\\\.\qquad \quad h=\sqrt{\dfrac{6^2(10)^2-35^2}{6^2}}\\\\\\.\qquad \quad h=\sqrt{\dfrac{2375}{36}}\\\\\\.\qquad \quad h=8.12[/tex]

Answer:

Please read the explanation!

Step-by-step explanation:

Hi! I will try to do my very best with helping you. Because there is not an example that goes along with this question, I will give my own.

Lets say we have triangle ABC in quadrant II. The Points are:

A: (-5,1)

B: (-3,5)

C: (-1,1)

If we plot that than we have a triangle. And when we reflect anything, not just a triangle, we would need to basically flip it over and mirror the image. The triangle will move, but it is the same triangle as it was before. All that has happened is that is was married to the otherside.

If you are a bit confused think of when you are in front of a mirror.

So let's reflect it over the y-axis.

When in doing so, you need to make sure that the x in (x, y) is changed into a positive number. We need to make sure that we know that quadrant I has positive x-axis.

So,

A becomes (5,1)

B becomes (3,5)

C becomes (1,1)

And if you plot that it should be flipped or reflected like a mirror image.

I really hope this helped!

Answer:

[tex]3^{10}[/tex]

Step-by-step explanation:

[tex]3^{8}*3^{2}=3^{8+2}=3^{10}[/tex]

Using the multiplication/product law of exponents, you can add the exponents up.

Answer:

3^10 and the law used would be the Product Rule for exponents.

Step-by-step explanation:

turning this question into an equation you would get:

3^8 * 3^2 = ?

The law you use in this situation is the product rule for exponents. If you have the same base number (in this case it is 3) with exponents and you are multiplying them, then you can add the exponent numbers and keep the base the same. This product rule looks like this:

A^x * A^y = A^(x+y)

Applying it to this question, you get

3^8 * 3^2 = 3^(8+2)

3^(8+2) is 3^10.

Therefore the simplified expression is 3^10.

What do we know?

There are 9 black pens and 3 green pens.

What else do we know?

We know that 11 of the pens aren't black, and 5 of them aren't green.

Black pens (9) : red pens (6) : green pens (3)

How'd I get 6?

If 11 pens aren't black, they had to be green, but 5 of them weren't green. So, I subtracted 11 from 5 to get 6 red pens.

I hope that makes sense.

Final answer:

9:6:3

WARNING: I could be wrong as I'm not fully sure, but this is what I think.

Answer

the next step is either 7-2 or 5 (Subtracting 2 from both sides)

solution is 20

Step-by-step explanation:

Answer:

5=p/4

Step-by-step explanation:

When you subtract 2 for both sides you are left with 5=p/4. The 2 was eliminated because 2-2=0.

Answer:

The minimum distance each should walk to cover the same distance is 12240 cm

Step-by-step explanation:

The minimum distance each should walk so that all can cover the same distance in complete steps is the same as the Lowest Common Multiple (LCM) of the three numbers, which is the least integer that is divisible by each of the three numbers.

To find the LCM, we will first find the lowest multiples of each of the numbers

80 ⇒ (2) × 2 × 2 × 2 × (5)

85 ⇒ 17 × (5)

90 ⇒  (2) × 3 × 3 × (5)

Note: in finding LCM, the numbers common to at least 2 (in bracket), out of the three terms is written just once.

∴ LCM = 2 × 2 x 2 × 2 × 3 × 3 × 5 × 17

= 16 x 9 x 85

= 12240 cm

Therefore, the minimum distance each should walk to cover the same distance is 12240 cm

Answer:

The probability of picking a yellow marble is 2/13

Step-by-step explanation:

First of all, we need to know the total number of marbles that are in the bag. To do this, we will have to add up all the marble colors together.

This will give us 6 + 2 +4+ 1 = 13 marbles in total.

The next step is to find the number of yellow marbles in the bag.

We can get this from the question. There are 2 yellow marbles in the bag.

The probability of selecting a yellow marble can be obtained by dividing the number of yellow marbles by the total number of marbles in the bag

This will give us 2/13.

Therefore, the probability of picking a yellow marble is 2/13

Answer:

Binomial

Step-by-step explanation:

Edited to add:

It can also be called a binomial because there are 2 unlike terms x and y. I'm not sure what you are studying, so it may be better to go with binomial. The Quartic is when you are looking at the degree of a single term polynomial.

You can name a polynomial based on terms, or based on degrees.

If it's based on degree it would be bi-quadratic, because it's ^4 and you have 2 different terms. If you're looking at terms it would be binomial because you have x and y to solve for.

The degree of terms is a major deciding factor whether an equation is homogeneous or not. A polynomial of more that one variable is said to be homogeneous if the degree of each term is the same. For example, 2x^7+5x^5y^2-3x^4y^3+4x^2y^5 is a homogeneous polynomial of degree 7 in x and y.

You have a 4 term polynomial with 2 variables x and y. The highest degree in your equation is 5 (4 + 1 from the first term) so the degree of the multivariable polynomial expression is 6.

All these answers are correct, it just depends what you're studying. If some of these words are new, and others you recognize from class or your book, go with the one that looks familiar.

Answer: 5th degree polynomial (quintic polynomial)

====================================================

Explanation:

5x^4y is the same as 5x^4y^1. The exponents 4 and 1 sum to 4+1 = 5

The term 3x^2y, or 3x^2y^1, has the exponents add to 3

The term 4xy has the exponents add to 2

The largest sum of exponents is 5, so we have a 5th degree polynomial

This is known as a quintic polynomial

Note: the degree of the polynomial is equal to the largest sum of exponents for each term, so the degree is 5.

Answer:

Step-by-step explanation:

In a right angled triangle, the side opposite to the acute angle theta given is always the opposite side of the triangle and the longest side is the hypotenuse.

Given the angle theta in a triangle to be 30 degrees and the hypotenuse to be 2 units, to ge the opposite side, we will use the trig identity SOH in SOH, CAH, TOA

Sin(theta) = Opposite/Hypotenuse

Substitute the given parameters into the expression

sin30° = Opposite/2

cross multiply

Opposite = 2 * sin30°

Opposite = 2 * 0.5

Opposite = 1 unit

Hence the length of the side of the triangle opposite to theta is 1 unit.
