Answer:
The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet
Step-by-step explanation:
we are given height equation as

where 
h is the height in feet of a Juggler's ball after t seconds 
now, we can plug t=1.5

we can solve for h 



So, 
The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet
 
        
             
        
        
        
I think you have to figure out the gradient, so you take the 2 points and put it into the equation
change in y divided by change in x aka
y2-y1/x2-x1
so for question 3:
y2=4 and y1=3 
(taken from the first and second coordinates)
x2=3 and y1=7
put these values jnto the equation
4-3/3-7 = 1/-4 (can be written as negative 1/4)
for question 4 its the same thing:
y2=9 and y1=5
x2=4 and x1=2
put into equation
9-5/4-2 = 4/2
hope this helps, im also hoping your teacher already has taught this because i didnt go into detail of where the equation came from, if not ask me and ill gladly help X
        
                    
             
        
        
        
No solution as they are parallel lines. so, inconsistent
        
             
        
        
        
Answer:
n = 1 if you meant "(4/5)n - (3/5) = (1/5)n"
Step-by-step explanation:                                                                               
There's some ambiguity here.  Did you mean (4/5)n or did you 
               4
mean --------- ?  Please use parentheses to eliminate this ambiguity. 
               5n    
I'm going to assume that you meant to type in (4/5)n - (3/5) = (1/5)n.
Then we have (3/5)n = 3/5, or n = 1
                                                                                                  
 
        
             
        
        
        
A rectangular prism is a cuboid so volume of cuboid is base area x height which is 5x5x12=300 
volume of pyramid is 1/3 x base area x height = 5x5x6x1/3=50 thus volume outside pyramid and inside cuboid is 300-50=250
