Answer:
400/81 cm²
Step-by-step explanation:
FE : DC
1 : 3
Since area ABCD = 400
s² = 400
s = 20
FE = ⅓(20) = 20/3 cm
IH : FE
1 : 3
IH = ⅓(20/3) = 20/9 cm
Area of HIJK:
(20/9)² = 400/81 cm²
 
        
             
        
        
        
Answer:

Step-by-step explanation:
the arc length is equal to the radius x angle (in radians)

s= arc length, r= radius and a= the angle
solve for a ; a= s/r; a= 

 
        
             
        
        
        
Answer:
3p^3 + qp^2 - pq^2 + 3q^3
Step-by-step explanation:
(p²-pq + q²) ( 3p+ 3q) 
3p^3 + 3qp^2 - 3qp^2 - 3pq^2 + 3pq^2 + 3q^3
3p^3 + qp^2 - pq^2 + 3q^3
 
        
             
        
        
        
Answer:

Step-by-step explanation:
We are given that 
Initial velocity=30 ft/s
Initial position=
We have to write a mathematical model for height of the softball by using the position equation 
The position equation on Earth's surface is given by 

Where  Initial velocity
 Initial velocity
 =Initial position
=Initial position
Substitute the values in the equation then, we get 

Hence, the mathematical model for height of the softball is given by
