An exponential model can be described by the function
f(x) = a(b)^x
where: a is the initial population or the starting number, b is the base and x is the number of periods elapsed.

When the base of an exponential model is greater than 1 it is called a growth factor, but when it is less than 1 it is called a decay factor.

Given the exponential model
n=20.5(0.6394)^t
n is the final output of the exponential model, 20.5 is the starting number, 0.6394 is the base and t is the number of periods/time elapsed.

Here, the base is 0.6394 which is less than 1, hence a decay factor.

Therefore, <span>the base, b, of the exponential model is 0.6394; It is a decay factor.</span>

Find the value of o.81 dividing o.o9 plus o.81 dividing nine my entire math grades depend on this please help me
tankabanditka [31]

Answer:

i believe its 9.09

Step-by-step explanation:

i did this problem 3 different ways

first i put it all in a calculator and got 9.09

then i did 0.81/0.09 = 9+ 0.81 = 9.81/9 = 1.09

finally i did 0.81/0.09 = 9    0.81/9 = 0.09

9+ 0.09 = 9.09

therefore 9.09 is what i believe the answer is

i hope this helps you!

Why did I get this question wrong?
lord [1]

Step-by-step explanation:

∫₀³⁰ (r/V C₀ e^(-rt/V)) dt

If u = -rt/V, then du = -r/V dt.

∫ -C₀ e^u du

-C₀ ∫ e^u du

-C₀ e^u + C

-C₀ e^(-rt/V) + C

Evaluate between t=0 and t=30.

-C₀ e^(-30r/V) − -C₀ e^(-0r/V)

-C₀ e^(-30r/V) + C₀

C₀ (-e^(-30r/V) + 1)

I got the same answer.  Try changing the lowercase v to an uppercase V.
