Answer:
number 10
dy/dx =(dy/dt).(dt/dx)
now find 
dy/dt=4t-1. , dt/dx=1
 so : dy/dx=(4t-1).(1)
 dy/dx= 4t-1 ,we have x=t-3-----> t=x+3
 subtitute at t
 dy/dx= 4(x+3)-1=4x+12-1= 4x+11
 
        
             
        
        
        
Answer:
1
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
     = (5-8)/(-8 - -5)
     = -3/(-8+5)
     = -3/-3
    = 1

Determine the volume
The volume of a cylinder is calculated as thus:

Substitute values for r and h


<em>Hence, the volume of the cylinder is 18312.48mm³</em>
