ROUNDING
<u>=================================================================</u>
There are two rules for rounding :
1. If the number you are rounding is followed by 0-4, you simply drop it.
2. If the number you are rounding is followed by 5-9, you add 1.
Let's see these rules in action!
3.892 -> followed by 2, which is in the set 0-4, we drop it
3.89 -> followed by 9, we add 1 to 8
3.9

Answer:
21.9
Step-by-step explanation:
The altitude of an isosceles triangle bisects the base. So, x represents the hypotenuse of a right triangle with legs of 9 and 20. It can be found using the Pythagorean theorem:
x^2 = 9^2 +20^2 = 81 +400
x = √481 ≈ 21.932
The length x is about 21.9 units.
Using linear function concepts, the meaning of the y-intercept of Ivania's position is given by:
Ivania begins the race 6 meters behind Javier.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Ivania's equation is given by:
y = 9x - 6.
The y-intercept is of -6, which is her relative position, given by:
Ivania begins the race 6 meters behind Javier.
