I believe the correct answer is 45 degrees. The smallest positive angle <span>θ in QI for which tan θ = 1 would be 45 degrees. We obtain it as follows:
</span>tan θ = 1
<span>θ = tan^-1 (1)
</span>θ = 45 degrees
Hope this answers the question. Have a nice day.
The length of the radius or r is 12 units.
It does not exist because the function is not continuous at -2.
Substitute -2 into both rules and they must equal the same number.
USING a TI-83 plus press Y= in Y1 put (2x+5)(x<-2) and in Y2 put (x+4)(x≥-2)
Arrow over in front Y1 and press ENTER until you see only 3 diagonal dots
Do the same in front of Y2.
Inequality signs are under 2nd MATH
Press GRAPH (You can see it is not continuous at -2)
