You're looking for c, so you want to isolate it or get it by itself. To get rid of the /3 you multiply since the opposite of division is multiplication and to get rid of it, you do the opposite (like -9 you would add 9 to get it to 0). Now you are left with -19+c = 24 (the 24 is 8*3 because what you do to one side you do to the other. Now you get c by itself so you add 19 to both sides which leaves you with C= 43. Sorry if this was confusing!
Radius is 15 cm
Circumference = 2 pi r
C = 2 x 3.14 x 15cm
C = 94.2 cm
94.2 cm x 4 (revolutions) = 376.8 = D
The axis of symmetry is X=-2
The vertex is (-2,4)
The maximum is 4
There is no minimum as the maximum is also the vertex of the parabola.
The zeros are (-4,0) and (0,0) or just 0 and -4
The domain is all real numbers from negative infinity to positive infinity
The range contains all real numbers less than or equal to 4 :)
I would I think it is yes I could be wrong though I apologize if I’m wrong
39 over 9th as a repeating decimal is 4.33 ( the 3 keeps repeating )
I hope this helps!
