Answer:
therefore the correct options are:
B. the equation is an exponential decay equation.
F. $28000 represents the initial cost of an automobile that depreciates 27% per year over the course of t years.
Step-by-step explanation:
i) the cost of an automobile is given by the equation is
C(t) = , where C(t) represents the cost and t represents the time in years
ii) the above equation is an exponential decay equation. It is a decay equation because growth rate is 0.73 which is less than 1 and greater than zero.
ii) when t = 0 then the cost is C(0) = 28000 represents the initial cost.
iii) from the equation in i) we can understand that the cost depreciates 27% per year over the course of t years.
therefore the correct options are:
B. the equation is an exponential decay equation.
F. $28000 represents the initial cost of an automobile that depreciates 27% per year over the course of t years.
Answer:
(a+b)/c
Step-by-step explanation:
a/c+b/c
since they have the same denominator you can add the numerator together
(a+b)/c
Answer:
25^4
Step-by-step explanation:
Here, we want to find the expression that shows the total number of pages in all of the news papers
Number of pages per book = 25
Number of schools is 25
Number of classrooms is 25
Number of students per classroom is 25
Now; the number of students in each school
is 25 * 25
Number of students in all of the school will be;
25 * 25 * 25
So the number of pages in all of the schools will be;
25 * 25 * 25 * 25 = 25^4
We can figure this out using the explicit formula.
n represents the term we are looking for.
f(1) represents the first term in the sequence, which in this case, is 7.
d represents the common difference, which in this case, is +3.
f(n) = 7 + 3(n - 1)
f(n) = 7 + 3n - 3
f(n) = 4 + 3n
Now, we can input 214 for n and solve.
f(214) = 4 + 3(214)
f(214) = 4 + 642
f(214) = 646
The 214th term in this sequence is 646.
