What is an ordered pair

An ordered pair is defined as any pair of numbers for which order is important. Clearly the order of coordinates for a given point is very important for example (5,2) and (2, 5) represent two very different points on a coordinate system. As shown in the image attached. Therefore, a given point such as (5,2), is often referred to as an ordered pair.

"In mathematics, an ordered pair is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair is different from the ordered pair unless a = b. Ordered pairs are also called 2-tuples, or sequences of length 2; ordered pairs of scalars are also called 2-dimensional vectors."

MAJOR HELP!

Answer:

The radius of the cone is 21 units

The volume of the cone is 9702 units³

Step-by-step explanation:

* Lets revise the area of the circle and the volume of the cone

- The base if the cone is a circle

- The area of the circle is πr², where r is the radius of the circle

∵ The area of the base of the cone = 1386 units²

∵ The area of the base = πr²

∵ π = 22/7

∴ 1386 = 22/7 (r²) ⇒ multiply each side by 7

∴ 9702 = 22 r² ⇒ divide both sides by 22

∴ 441 = r² ⇒ take √ for both sides

∴ 21 = r

* The radius of the cone is 21 units

- The volume of the cone = 1/3 πr²h , where h is the height of the cone

∵ The cone's height is equal to the radius of its base

∴ h = r

∵ The volume of the cone = 1/3 πr²h

∴ The volume of the cone = 1/3 πr²(r) = 1/3 πr³

∵ r = 21 units

∴ The volume of the cone = 1/3 (22/7) (21)³

∴ The volume of the cone = 9702 unit³

* The volume of the cone is 9702 units³

Largest odd number by using all four (4) cards <br><br> 5,3,2,6

dlinn [17]

Answer:

6523

Step-by-step explanation:

I'm assuming that the question is asking us to rearrange the numbers 5,3,2,6 to obtain the largest possible value that is odd.

In order for a number to have the largest value, the first digit of the number must he the largest possible value. In this case, we see that the largest value is 6, hence the number must begin with 6 i.e 6XXX

We can do the same for the next digit in the hundreds position by picking the largest possible remaining number. In this case, it is the number 5. So the number will look something like this: 65XX

We see that the only remaining numbers are 3 and 2.

Recall that for a number to be odd, the digit on the ones place must also be odd. Of the remaining numbers, only 3 is odd, hence the last number must be 3. i.e 65X3

Hence the last remaining number is 2

Mary says the pen for her horse is an acute right triangle. Is this possible? Explain.

Vadim26 [7]

Mary means it's a right triangle and therefore the other two angles are acute, if the two angles are congruent then it's an isosceles right triangle. if not the same it's a scalene right triangle Mary has to know when classify triangles by angle measure it has to be one type of angle either a right, acute or obtuse by sides isosceles and scalene Hope this helps
