Answer:

  yes

Step-by-step explanation:

The side lengths satisfy the Pythagorean theorem, so the triangle is a right triangle.

  7.5² +10² = 12.5²

  56.25 +100 = 156.25

_____

You may recognize that the ratios of side lengths are ...

  7.5 : 10 : 12.5 = 3 : 4 : 5

A 3-4-5 triangle is a well-known right triangle, as this is the smallest set of integers that satisfy the Pythagorean theorem. They also happen to be consecutive integers, so form an arithmetic sequence. Any arithmetic sequence that satisfies the Pythagorean theorem will have these ratios.

_____

If you're familiar with trigonometry, you know the law of cosines tells you ...

  c² = a² + b² - 2ab·cos(θ) . . . . where θ is the angle between sides a and b. This reduces to the Pythagorean theorem when θ=90°, which makes cos(θ)=0. If the sides do not satisfy the Pythagorean theorem, cos(θ)≠0 and the triangle is not a right triangle.

Which of the following ordered pairs could be in a relation that has a range of {2, 4, 5}?
hodyreva [135]

Answer:

d) (3, 4), (5, 5), (5, 2)

Step-by-step explanation:

<em></em>

<em>We are asked to determine which orderpair in the option has the range of {2,4,5}</em>

Using the definition of range:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

So in the given options if we write the relation in the form of (x,y) then 4, 5, 2 are the values in the range
