rounding
7.2 to 7
7.5 to 8
7.9 to 8

7 and 8 and 8

3+3.75+3.75=10.50

she has 10.25
10.25-10.50=-0.25

Is the relation a function (14,15),(5,7),(3,10),(11,1),(5,8)

Answers

A set of ordered pairs is called a $\textit{relation}$ :

{(14,15),(5,7),(3,10),(11,1),(5,8)} is a relation.

The pairs are called "ordered" because the order is important, for example:
(3, 4) and (4, 3) are 2 different things. In the first pair 3 is the $\textit{first coordinate}$ , but in the second one 3 is $\textit{second coordinate}$

A relation is a $\textit{function}$ if no 2 first coordinates of the points are equal.

In the given relation, the first coordinates of points (5,7) and (5,8) are equal, so the relation is not a function.

Answer: No

Answer:

Step-by-step explanation:

What is the value of x, given that modifying above upper P upper Q with bar parallel to modifying above upper B upper C with bar ? The figure is triangle A B C with a segment from point P on segment A B to point Q on segment A C. Segment A P equals 9. Segment P B equals 18. Segment A Q equals x. Segment Q C equals 10.

After addressing the issue at hand, we can state that As a result, the equation value of x is roughly 10.57 units (rounded to two decimal places).

What is equation?

An equation is a mathematical proclamation that proves the equality of two expressions capable of connecting through an equal sign '='. For instance, 2x - 5 = 13. Explanations include 2x-5 and 13. The '=' symbol links up the two expressions. A mathematical formula containing two formulas on either side of a =) (=) is known as an equation. It depicts the equivalence relationship between left and right methodologies. L.H.S. = R.H.S. (left edge = top half) in any formula.

Using the information provided, we can construct the following equation based on the concept of similar triangles:

x/(9+18) = 10/(BC) (BC)

9 + 18 = 27 = AB = AP + PB

Because triangle ABC is a right triangle (angle B is 90 degrees), we can apply the Pythagorean theorem to calculate the length of segment BC:

BC2 = AB2 - AC2 BC2 = 272 - 102 BC2 = 649 BC = sqrt (649)

When we plug this value into our original equation, we get:

x/(9+18) = 10/sqrt (649)

When we simplify, we get:

x/27 = 10/sqrt (649)

When we multiply both sides by 27, we get:

x = 270/sqrt (649)

As a result, the value of x is roughly 10.57 units (rounded to two decimal places).
