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:
y=3x- 3/2
Step-by-step explanation:
4.2x−1.4y=2.1
Subtract 4.2x from each side
4.2x-4.2x−1.4y=-4.2x+2.1
-1.4y = -4.2x +2.1
divide each side by -1.4
-1.4y/-1.4y = -4.2x/ -1.4 +2.1/-1.4y
y=3x- 3/2
Step-by-step explanation:
8x-10=3x+90
=5x=100
=x=20
therefore
B=3(20)+90
150°
G = 2 inches
The first shape is 6 and 12. The two shapes are similar to each other, so the other shape must be 1 and 2. 6 divided by 6 is 1 so 12 divided by 6 is 2.
The point-slope form of the equation of a straight line is:
We have:
Substitute:
