Answer:
x+4/x-4
Step-by-step explanation:
=x/(x-4)+4/(x-4) [ l.c.m= (x-4)]
=x+4/x-4
Answer:
the answer is in the attached image below
Step-by-step explanation:
the dot plot, because box plot only shows the 5 number summary and histograms show ratios
Answer: d
Step-by-step explanation:
First, lets transform the given vector into an unit vector (dividing by its module)
UnitVec = 4/5 i + 3/5 j
Then lets change this vector into a polar form
UnitVec = 1. with angle of 36.869 degrees taking as a reference the i vector
Then, the probem tells us that the vectors u and v make an angle of 45 degrees with UnitVec, so lets add+-45 to the vector in polar form
U = 1*[cos(36.869 +45)i + sin(36.869 +45)j] = 0.1414 i + 0.9899 j
V = 1*[cos(36.869 -45)i + sin(36.869 -45)j] = 0.9899 i - 0.1414 j
