Area of rectangle prism, to find the answer, use this formula: 2 x ( h x d + h x w + d x w )
So it would look like this: 2 x ( 12 x 6 + 12 x 7 + 6 x 7 ) = 396
I would say the answer is B. 396 in2
Hope I helped ; )
Answer:
38.26 years.
Step-by-step explanation:
We have been given that the population of an endangered animal by reduces 8% per year. the current population of the animal is 1700. When the population of this animal falls below 70, its extinction is inevitable.
Let us write the model for population of this animal (y) after x years.
Since we know that an exponential decay function is in form:
, where,
a= Initial value.
r = Rate in decimal form.
Let us convert our given rate in decimal form.

Upon substituting a= 1700 and r = 0.08 in exponential function, we will get the model of animal population as:


Let us find, when the animal population will face extinction by substituting y=70 in our function.

Let us take natural log of both sides of our equation.




Therefore, the population of the animal will face extinction after 38.26 years.
<u>Answer:</u>
29 years
<u>Step-by-step explanation:</u>
- Given the function
, where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover. - Another way of doing this is to change the function to
which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate. - I'll use the 1st function because the question doesn't ask for the rate

From here I'll just use a calculator & get 28.7, or 29 years.
