(1-sin^2(x))tan(-x) is not equivalent

Mathematics

Zinaida [17]3 years ago

We can simplify (1 - sin^2 (x)) tan(-x) as
-cos^2 (x). sin(x)/cos(x) = -cos(x) sin(x)
Since sin^2 (x) + cos^2 (x) = 1 and tan (-x) = -tan (x). (It may also be useful to know that cot (-x) = -cot(x) which will be incorporated in my solution later)

You rent an apartment that costs $1100 per month during the first year, but the rent is set to go up 9.5% per year. What would b
uranmaximum [27]

Answer:

  $2076.30

Step-by-step explanation:

In the n-th year, the rent will be ...

  an = a1·r^(n-1) . . . . . . . . . r is the year on year ratio: 1+rate of increase

  an = 1100·(1.095^(n-1))

Then the rent in the 8th year is ...

  a8 = 1100·(1.095^(8-1)) ≈ 2076.30

The rent in the 8th year would be $2076.30.
