Calculate the velocity of a baseball that travels 100 m in 5 sec.
r-ruslan [8.4K]

The velocity of the baseball is 20m/s

Velocity can be described as the speed of an object that is moving in a particular direction

The formula for calculating velocity is

velocity= displacement/time

The first step is to write out the parameters given in the question.

time= 5 seconds

displacement= 100m

The velocity can be calculated as follows;

velocity/displacement

= 100/5

= 20

Hence the velocity of the ball is 20m/s

Please see the link below for more information on velocity

Somebody please help with this problem
Mrrafil [7]

Step-by-step explanation:

We have been given that AE=BE and \angle1\cong \angle2.

We can see that angle CEA is vertical angle of angle DEB, therefore, m\angle CEA=m\angle DEB as vertical angles are congruent.

We can see in triangles CEA and DEF that two angles and included sides are congruent.

\angle 1\cong \angle 2

AE=BE

\angle CEA\cong\angle DEB or \angle 3\cong \angle 4  

Therefore, \Delta CEA\cong \Delta DEB by ASA postulate.

Since corresponding parts of congruent triangles are congruent, therefore CE must be congruent to DE.

Let f(x)=4x+9. Write a function g whose graph is a reflection in the y-axis of the graph of f. g(x)= ?
frez [133]

Answer:

g(x)=-4x+9

Step-by-step explanation:

So we know that:

f(x)=4x+9

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

g(x)=f(-x)=4(-x)+9

Simplify:

g(x)=-4x+9

And that's our answer :)
