Well diameter will be the diagnol of that square..
let side of square be x, then diagonal will be root2 * x  = diameter
so, raidus will be = dia/ 2
 = (root2 * x ) /2
        
             
        
        
        
Answer:
5x
Step-by-step explanation:
=> 6x-x
<u><em>Taking x common</em></u>
=> x(6-1)
=> x(5)
=> 5x
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The question asks to represent the position of two animals in a the cartesian coordinates plane. This is two perpendicular axis, the y-axis is the vertical one and the x-axis is the horizontal one. The animals are represented by dots, called a for the seagull and b for the shark.
Since the y-axis is the vertical axis and they ask to draw the points with a verical difference between them, we will draw the points in it.
Say the x-axis represents the sea surfice. The seagull would be over the sea, and the shark under the sea surfice (under x-axis).
This is the resulting drawing
 
        
             
        
        
        
Answer:
 = 4
 = 4 
Step-by-step explanation:
There is a common ratio r between consecutive terms , that is
r = - 20 ÷ 4 = 100 ÷ - 20 = - 5
This indicates the sequence is geometric with nth term ( explicit formula )
 = a₁
 = a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 4 and r = - 5 , then
 = 4
 = 4
