Height of the pentagon = 9 ft
Edge of base = 3 ft 

s is the length of any side = 3
n is the number of sides = 5 
tan is the tangent function calculated in degrees 

Volume of the pentagon = area of base (height )
Volume of the pentagon = 15.4852 (9)
Volume of the pentagon = 139.366
Volume of the pentagon = 139.37 cu.ft

64,000 exponential function  
Step-by-step explanation:
64,000 exponential function  
The number of bacteria in a colony doubles  every 210 minutes.
The population of bacteria = 8000
Determine how many times the population will double.

  = 3
Multiply the population by 2 a total of 3 times.
8000 × 2³ = 64,000
 
        
             
        
        
        
Answer:
1/5
Step-by-step explanation:
We can find the slope of a line given two points by using the following
m = ( y2-y1)/(x2-x1)
     = ( 3-0)/(7 - -8)
     = ( 3-0)/(7+8)
      = 3/15
     = 1/5
