To find the acceleration we divide the change of velocity by the change of time.
Change of velocity: 4 m/s
Change of time: 2 s

Acceleration = \frac{4}{2} = 2

So the answer: his acceleration is 2 m/s^2

In this figure, a line through points X & Y will _____
levacccp [35]

From the figure, its clear that the compass drew arcs like below:

With A as centre, and more than half of the length of AB as radius, one arc is drawn.

With the same radius, with B as centre, another arc is drawn.

The points of intersections of the arcs are X and Y.

Clearly, this is the construction of a perpendicular bisector of the line segment AB.

Hence, if we draw a line segment through XY, it will be a perpendicular bisector of AB.

The equation of the hyperbola that has a center at ( 6 , 9 ) , a focus at ( 11 , 9 ) , and a vertex at ( 9 , 9 ) (x−C)^2/A^2−(y−
MrMuchimi

Answer:

A=-3

C=6

B=4

D=9

Step-by-step explanation:

From the question we are told that:

Center of hyperbola at ( 6 , 9 )

Focus of hyperbola at ( 11 , 9 )

Vertex of hyperbola at ( 9 , 9)

Equation of hyperbola \frac{(x-C)^2}{A^2} -\frac{(y-D)^2}{B^2}=1

Generally the C and D of the hyperbola equation is mathematically given by

Centers (6,9)

C=6

D=9

Generally the A and B a of the hyperbola equation is mathematically given by

 A=x_c-x_v

 A=6-9

 A=-3

 C'=x_c-x_f

 C'=6-11

 C'=-5

Therefore with Center,Focus ,Vertex on the same line

 B^2=C'^2-A^2

 B^2=(-5^2)-(-3^2)^2

 B^2=(25)-(9)

 B^2=16

 B=4
