6) x= 2, angle = 90 degrees obviously
7) Im not sure on this one
8) x = 5
9) x = 1
indica que as duas variáveis movem-se em direções opostas, e que a relação também fica mais forte quanto mais próxima de menos 1 a correlção ficar. Duas variáveis que estão perfeitamente correlacionadas positivamente (r=1) movem-se essencialmente em perfeita proporção na mesma direção, enquanto dois conjuntos que estão perfeitamente correlacionados negativamente movem-se em perfeita proporção em direções opostas.
Answer:
c isyour answer
Step-by-step explanation:
Answer:
Option A i.e. y = - 3 is not in range of the piece wise function graphed.
Step-by-step explanation:
The range of a function y = f(x) is given by the possible values of y for the possible domain (x-values) of the function.
Now, it is clear from the graph of the function that the value of y never goes below y = - 2.
The graph is drawn in such a way that any value of y less than - 2 and greater than - ∞ is not in the range of the function.
Therefore, option A i.e. y = - 3 is not in range of the piecewise function graphed. (Answer)
Answer:
Option B
The solution in the attached figure
Step-by-step explanation:
we have
<em>Inequality A</em>
we know that
The solution of the inequality A is the shaded area above the dashed line
The equation of the dashed line is 
The slope of the dashed line is negative 
<em>Inequality B</em>
we know that
The solution of the inequality B is the shaded area above the dashed line
The equation of the dashed line is 
The slope of the dashed line is positive 
therefore
The solution in the attached figure
