Answer:
Step-by-step explanation:
Well if you want the answers there are 3 different ways
x = 12/5
or
x = 2.4
The common form of exponential function is y = xᵃ where x is the variable and a is raised to a specific number. From this, the graph would on the value of a. An example would be when there are 70000 bacteria
present in a culture and reduced by half every four hours, the number of
bacteria will decrease. The bacteria will experience an exponential decay
because it decreases its number at a constant decay.
The short answer: yes.
Explanation: every rational number can be expressed as, well, a ratio. For instance, 5 can be expressed as 5/1 and 1.75 can be expressed as 7/4. Irrational numbers are not rational. For instance, pi... there is no ration for pi.
Answer:
The equation is
at a rate of -23%.
Step-by-step explanation:
Decay can be represented by the equation
. We can find the rate at which it decays by using t=3 hours and A=3000. This means
in this context.
After substituting, we divided by 6000 to each side to get 0.5 on the left. Now to solve for r, we will take the natural log of both sides and use log rules to isolate r.
We know
so we were able to cancel it out and divide both sides by 3.
We solve with a calculator
We change -0.23 into a percent by multiplying by 100 to get -23% as the rate.
The equation is
Answer:
well the answer is 0.185
