Answer:
As x decreases without bound, f(x) increases without bound
As x increases without bound, f(x) approaches 0
Step-by-step explanation:
As x gets more and more negative f(x)  gets bigger and bigger
f(x) = (7/10) ^ x but x is negative  so flip it and then x is a larger number
        (10/7) ^  large number   so it will get larger
  as → -∞   f(x) →∞    
As x gets more and more positive f(x)  gets smaller and smaller
f(x) = (7/10) ^ x   closer and closer to 0.  The denominator gets larger faster than the numerator  = 1 / large number
        
  as → ∞   f(x) →0    
 
        
             
        
        
        
Given:
The measurement of the angles of a triangle are 3b,2b,and 4b.
To find:
The smallest angle.
Solution:
According to the angle sum property, the sum of all angles of a triangle is 180 degrees.
 [Angle sum property]
           [Angle sum property]

Divide both sides by 9.

Now,



Therefore, the smallest angle is 40 degrees.
 
        
             
        
        
        
Answer:
The radius of hole is 5 feet
Step-by-step explanation:
Depth of conical hole = 9 feet 
Let the radius of hole be r 
Volume of conical hole =
So, Volume of conical hole =
We are given that volume of a CONE-shaped hole is 75pi ft cubed. 
So,



r=5 
Hence The radius of hole is 5 feet
