3. Does it matter which number comes first in an ordered pair? Explain.

yes

Step-by-step explanation:

This is because if you have the order pair (5,2) and you go up first instead of over first then that would be the order pair (2,5) wich would be a different point on the graph. Always go over and then up.

Yes, the order of the numbers in an ordered pair does matter and here’s why:

If you think about an ordered pair, you know that the first number is the x-coordinate and the second number is the y-coordinate. On a graph, the x-coordinate tells you how far left or right the point is (positive goes right and negative goes left) and the y-coordinate tells you how far up or down the point is (positive goes up and negative goes down). If you have an ordered pair (6,2) for example, if you started at the origin (0,0) of a coordinate plane, you would go 6 units to the right and 2 units up. If you flipped the numbers (2,6) you would the go 2 units to the right and 6 units up. These two points (6,2) and (2,6) are not the same, so the order does matter.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general
