Answer:
The value of f(5) is 3.2.
Step-by-step explanation:
It is given that f(1) = 3.2 and

Substitute x=1 in the above equation.


Substitute x=2 in the given equation.


Substitute x=3 in the given equation.


Substitute x=4 in the given equation.


Therefore the value of f(5) is 3.2.
 
        
                    
             
        
        
        
For this case we have an equation of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: decrease rate
 t: time in years.
 Substituting values we have:
 7 = A * (0.5) ^ ((1/20) * t)
 For t = 45 years we have:
 7 = A * (0.5) ^ ((1/20) * 45) 
 Clearing A:
 A = 7 / ((0.5) ^ ((1/20) * 45))
 A = 33.3
 Answer:
 the density of the substance when it was deposited 45 years ago was:
 A = 33.3 milligrams per square centimeter

Answer:
1. KL = 29
2. angle J = 127 degree
3. angle of K = 53 degrees
Step-by-step explanation:
SInce it is a parrallelograme, one thing that will help you is to remember that opposits are the same.
1. KL = JM since they are opposite => KL = 29
2. angle J = angle L since they are opposite => angle J = 127 degrees
3. Since we know that angle J and L are both equal to 127 degree and since the sum of the angles of a parralelogram is 360 degrees, so the sum of the angles of K and M is:  360 - 127 - 127 = 106 degrees.
Since K's and M's angles are equale => 106 / 2 = 53 degrees.
