Answer:
-1.2
Step-by-step explanation:
Given that the designer also programs a bird with a path that can be modeled by a quadratic function.
 The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).
If we treat this curve as line joining these two points then we can find the slope by the formula
Slope = change in y coordinate/change in x coordinate
Here the points given are
(0,20) and (10,8)

Slope of the line that represents the turtle's path
=-1.2
 
        
             
        
        
        
Answer:
The correct option is C.
Step-by-step explanation:
The least common multiple (LCM) of any two numbers is the smallest number that they both divide evenly into. 
The given terms are  and
 and  .
.
The factored form of each term is


To find the LCM of given numbers, multiply all factors of both terms and common factors of both terms are multiplied once.


The LCM of given terms is  . Therefore the correct option is C.
. Therefore the correct option is C.
 
        
                    
             
        
        
        
Answer: 14
Step-by-step explanation:
Given
Excavation cone measures 
height 
Diameter 
Truck can dump  at a time
 at a time
The volume of a cone is 

Putting values

No of trips(N) required to accumulate this much volume is given by

Therefore, 14 trips are necessary to accumulate a cone of volume
