At the end of each year, the value is 100% -15% = 85% = 0.85 what it was at the beginning of the year. After 3 years, the value is
.. 18,000*0.85^3 = 11,054.25

Remember,

sin = op/hyp

cos = adj/hyp

tan = op/adj

For question 3 it would be B and C, because the adjacent side of angle x is 12, the hypotenuse is 37, and cos = adj/hyp.  Also, the opposite side of angle z is 12, and the hypotenuse is 37, and sin = op/hyp.  So both answers would be 12/37. You would do the same with question 4.

For 5, you would do the same thing.  It would be D because you can only take the sin of angle 24, and x is a side.  the opposite of 24 is x and the hypotenuse is 11, so sin 24 would be x/11. It is the same for problem 6.

In 1985, there were 285 cell phone subscribers in Arlington. The number of subscribers increased by 75% per year since 1985. Fin
ANTONII [103]

Answer:

The number of subscribers in 2008 is 110,845,988

Step-by-step explanation:

The number of cell phone subscribers in Arlington, in t years after 1985, can be modeled by the following equation.

N(t) = N(0)(1+r)^{t}

And which N(0) is the number of subscribers in 1985 and r is the rate it increases per year, as a decimal.

In 1985, there were 285 cell phone subscribers in Arlington.

This means that N(0) = 285

The number of subscribers increased by 75% per year since 1985.

This means that r = 0.75

So

N(t) = 285(1.75)^{t}

Find the number of subscribers in 2008.

2008 is 2008-1985 = 23 years after 1985. So we have to find N(23).

N(23) = 285(1.75)^{23} = 110,845,988

The number of subscribers in 2008 is 110,845,988
