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

102521153
Step-by-step explanation:
The answer I found was 102521153.
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.
