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:
14w
Step-by-step explanation:
Width = w
Length is 6 time its width. so, multiply w by 6
length = 6*w = 6w
Perimeter of rectangle = 2* (length + width)
= 2*(6w + w)
= 2*7w
= 14w
Answer:
x = 27
y = 29
Step-by-step explanation:
Answer:
4x+18
Step-by-step explanation:
Length = x+3+x+3
width = x+3-x= 3
perimeter = x+3+x+3+x+3+x+3+3+3=4x+18
More than 5 sides have octagons and hexagons
so
8+14=22
altogether 8+14+24+5 =22+29=51
P=22/51
