In the diagram of parallelogram HIJK below, the diagonals HJ and IK are perpendicular, as shown. If HJ is 10 inches long and IK
guapka [62]

Answer:

It is the hypotenuse of a right triangle with legs 5 and 12.

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. If the angle at which they meet is a right angle, then a right triangle is formed whose legs are half the length of each of the diagonals, and whose hypotenuse is the length of one side of the parallelogram (rhombus).

Here, the triangle's leg lengths are 5 and 12, so the Pythagorean theorem tells us the hypotenuse is ...

  √(5²+12²) = √(25+144) = √169 = 13

Since the perpendicular diagonals are 10 and 24 inches long, the side length of the rhombus must be 13 inches long.

HK must be 13 inches because the Pythagorean theorem applies and that's what it says.

What are the domain and range of the function f(x)= Squrt x-7+9
AnnyKZ [126]

Answer:

  • domain: x ≥ 7
  • range: f(x) ≥ 9

Step-by-step explanation:

The domain is the set of values of x for which the function is defined. Those are the values of x that make the square root argument non-negative:

  x -7 ≥ 0

  x ≥ 7

__

Since the square root cannot be negative, the sum of it and 9 cannot be less than 9. The range is ...

  f(x) ≥ 9
