Answer:
I think these should help.
Step-by-step explanation:
There's nothing to multiply. However, you can factor it to get (x + 4)(x - 4).
Dy/dx=2x+2
So velocity will be zero when 2x+2=0, x=-1
Since d2y/dx2=2, it has a constant positive acceleration of 2, so that when dy/dx=0 it is at an absolute minimum value for f(x), which is also the vertex.
y(-1)=1-2+3=2
So the vertex is at (-1,2), which is an absolute minimum so the parabola opens upwards.
And by symmetry we can say that f(0)=f(-2)=3 so you have another two points that you can see (-2,3) and (0,3)
Answer:
0.24
Step-by-step explanation:
also i see what you did there
60 because .7 times 60 equals 42 therefore the answer is 60
