Answer:
Relation 3 is a function and Relation 4 is nog
 
        
             
        
        
        
The first term is 2 and the common ratio = -8/2 = -4
S7   = 2 * (-4)^7 - 1
                -------------    =      6554   answer
                  -4-1
        
             
        
        
        
Answer:
12
Step-by-step explanation:
since tile B is a regular polygon means it is an equilateral triangle. The angle inside B would be  60.
(360 - 60)/2 = 150 (interior angle of tile A)
180 - 150 = 30 (exterior angle of tile A)
therefore number of sides = 360 /30 = 12 
 
        
             
        
        
        
According to the question statement, the total sum of students is 221, which includes the students that ride on bus and the students that ride in a van.
The students that ride in a van are five, the students that ride on bus are 6 times s which is the product of the number of buses and the number of students that are on each bus. 
Write all this information into an equation, this way:

Now, solve the equation for s to find the number of students that are on each bus.

There are 36 students on each bus.
