This means that the door is open because half of a circle (360) is 180 and that means it’s open because u can’t open a door all the way at a 360
y = 3(x + 4)^2 + 31
Step-by-step explanation:
We can convert the given quadratic equation into its vertex form by completing the square:
y = 3x^2 + 24x + 43
= 3(x^2 + 8x) + 43
= 3(x^2 + 8x + 4) + 31
= 3(x + 4)^2 + 31
This is the vertex form of the given quadratic equation with (-4, 31) as its vertex
The is going to be infinite answers
1] 0.23
2] both are same
3] 20/100 *80= 16
