Así, concluimos que la posición final del buzo será 7 metros bajo la superficie del agua.
<h3 /><h3>¿a qué profundidad se encuentra al final de su recorrido?</h3>
Primero, vamos a definir la superficie del agua como el 0 metros.
Sí sabemos que primero el buzo se sumerge 4 metros, entonces en este punto la posición del buzo es:
P = 0m - 4m = -4m
Luego el buzo sube 2 metros, entonces la nueva posición será:
P = -4m + 2m = -2m
Finalmente, el buzo desciende otros 5 metros, entonces la posición final del buzo será:
P = -2m - 5m = -7m
Así, concluimos que la posición final del buzo será 7 metros bajo la superficie del agua.

Given:
The piecewise function is
To find:
The range of given piecewise function.
Solution:
Range is the set of output values.
Both functions 
and 
as linear functions.
Starting value of is at x=-4 and end value is at x=3.
Starting value: 
End value: 
Starting value of is at x=3 and end value is at x=6.
Starting value: 
End value: 
Least range value is 0 at x=-4 and 0 is included in the range because -4 is included in the domain.
Largest range value is 11 at x=6 and 11 is not included in the range because 6 is not included in the domain.
So, the range of the given piecewise function is [0,11).
Therefore, the correct option is A.
Answer:
Rachel
Step-by-step explanation:
We need to measure how far (towards the left) are the students from the mean in<em> “standard deviations units”</em>.
That is to say, if t is the time the student ran the mile and s is the standard deviation of the class, we must find an x such that
mean - x*s = t
For Rachel we have
11 - x*3 = 8, so x = 1.
Rachel is <em>1 standard deviation far (to the left) from the mean</em> of her class
For Kenji we have
9 - x*2 = 8.5, so x = 0.25
Kenji is <em>0.25 standard deviations far (to the left) from the mean</em> of his class
For Nedda we have
7 - x*4 = 8, so x = 0.25
Nedda is also 0.25 standard deviations far (to the left) from the mean of his class.
As Rachel is the farthest from the mean of her class in term of standard deviations, Rachel is the fastest runner with respect to her class.
If you use a ruler and if it's more than 120° its not a right triangle it has to be 120°
