X^2 +6x-6=0 taking -6 to cross the equal sign
x^2+6x=6 by completing squ.
x^2 +6x+ 9= 6+9
x^2 +6x +9 =15
(x+3)^2= 15
x+3= 15^0.5
x= 3,87298-3 or -3.87298-3
x= 0.87298 or -6.87298
We have to break each degree in terms of 90
A) 
Which is in third quadrant, therefore sine is negative hence
B) 
Which is in third quadrant, therefore cosine is negative hence
C) 
Which is in third quadrant, therefore tangent is positive hence
D) 
Which is in third quadrant, therefore cosec is negative hence
not defined
E)
Which is in third quadrant, therefore secant is negative hence
F) 
Which is in third quadrant, therefore tangent is positive hence
not defined
Hence only 
and
have value -1
Hope this will help
C is the correct graph because u can't get a cubed root of a negative number
if u chose 8 to bring x the cubed root is 2 and 2 - 3 = -1...graph matches
Answer:
$21.80
Step-by-step explanation:
50% of 38 is 19. 10% of 38 is 3.8. Add these together to get 21.8. This equates to $21.80.
I must assume that your graph is that of a straight line, and that the end points of the line are P and B, and (finally) that T is between P and B. If these assumptions are correct, then the length of the line segment PB connecting points P and B is 15 + 10, or 25.
