Answer:
The kinetic energy of an object is given by: Kinetic energy = 1/2 * mass * velocity If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0
 
        
                    
             
        
        
        
Answer:
x = 4
Step-by-step explanation:
ΔTRQ is an isosceles right triangle, so if we find the value of RT then the value of 'x' will be the same
We can find RT by creating a proportion based on the ratio of sides in a 30-60-90° triangle which, respectively, is 1 :  : 2
 : 2
2 /RT =
/RT =  /2
/2
cross-multiply:
 · RT = 4
· RT = 4
RT = 4
Therefore, x = 4
 
        
             
        
        
        
You can think of this equation as 

and thus apply the transformations to it as such



1)  D = 2, C = +3
2) D = -12, C = -2
3) C = +6, D = 3
4) C = -7, D = -7
 
        
        
        
Answer:
Option D -Parallelogram  and rhombus is the correct answer.
Step-by-step explanation:
<u>Option A -Square.</u>
In square all sides are equal and all angles are equal and each angle is equal to 90°
<u>Option B - Parallelogram </u>
In Parallelogram  opposites sides are equal and parallel. there is no right angles.
<u>Option C -Rectangle</u>
In rectangle opposites sides are equal and parallel. All angles are equal to  90°
<u>Option D -Parallelogram  and rhombus</u>
In Parallelogram  opposites sides are equal and parallel. there is no right angles.
In rhombus all sides are equal and parallel. there is no right angles.
Therefore correct answer is option D
