In the right triangle, angle B equals 60° and AB equals 18<br><br>How long is AC? <br>I'm stuck!
svlad2 [7]

Answer:

AC = 15.588

Step-by-step explanation:

(all rounded to nearest thousandth)

sin(60) = x/18

first solve: sin(60) = 0.866

0.866 = x/18

multiply 18 on both sides

x = 15.588

The value of a book is $150 and decreases at a rate of 4% per year. Find the value of the book after 12 years
nevsk [136]
If it decreases at 4% every year, then its value becomes:

100% - 4% = 96% = 96/100 = 0.96

At the end of the 1 year its value becomes:  150*(0.96)

At the end of the 2 years its value becomes:  150*(0.96)*(0.96) = 150*(0.96)²

At the end of the 3 years its value becomes:  150*(0.96)*(0.96)*(0.96) = 150(0.96)³

So similarly at the end of 12 years, its value becomes 150*(0.96)¹²

=50*(0.96)¹²    simplify with calculator.

<span>≈ 91.91

Value at the end of 12 years becomes ≈ $</span><span>91.91

I hope this helps.
