Answer: Length = 2x✓15

Step-by-step explanation:

A rectangle has a width of 2x inches and a diagonal length of 8x inches. We are told to find the length of the rectangle. The square of the diagonal is the addition of the square of the length and square of the width.

Adjacent² = length² + width²

(8x)² = length² + (2x²)

Length² = 64x² - 4x²

Length² = 60x²

Length = ✓60x²

Length = ✓4 × ✓15 × ✓x²

Length = 2 × ✓15 × x

Length = 2x✓15

If a person invests $250 at 9% annual interest, find the approximate value of the investment at the end of 15 years.
Ne4ueva [31]

Assume compounding once per year. Then A = P(1+r)^t, where r is the annual interest rate as a decimal fraction and t is the number of years.


Then A = Value after 15 years = $250(1+0.09)^15 = $910.62

Find the values of x and y for which the quadrilateral below must be a parallelogram.
Fofino [41]
Since there is no picture, find here-under the conditions that a quadrilateral becomes a parallelogram:
( All are either or)
1- opposite sides should be congruent
2- opposite angles should be congruent
3- opposite sides parallel
4-The sum of 2 adjacent angles to equal 180°
5 the 2 diagonals intersect in their middle

With any of these conditions, if confirmed, you can conclude that the quadrilateral is a parallelogram (By the way a rectangle is a parallelogram with one angle =90°

for each of these relations on the set {1, 2, 3, 4}, decide whether it is reflexive, symmetric, antisymmetric, or transitive. {(
Rama09 [41]

Relationship R is not symmetric and is not reflexive, R is not an asymmetric relation, R is a transitive relation as represented in image.

What is a relation?

  • Both the relationship and the function are fairly similar to one another. After learning about function and relation, we can then study how they differ from one another. This is how we can distinguish between relation and function.
  • The connection can be viewed as a set of ordered pairs in discrete mathematics. The sets must not be empty in order for it to be used to connect an object through one set to the other. The relation may include two sets or more.
  • The relation in mathematics is the connection between different sets of values. Assume that there are different pairs of ordered pairs, x and y.

If set x and set y are related, then set x's values are referred to as its domain while set y's values are referred to as its range.

Relationship R is not symmetric and is not reflexive, R is not an asymmetric relation, R is a transitive relation as represented in image.

He is incorrect because any number multiplied by 1 will stay the same, and so if he is going to multiply it by numbers less than one, he will have a lower number.
