Answer:

w = 9.82

x = 66.73

Step-by-step explanation:

By applying tangent rule in triangle ABD,

tan(81°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

6.31 = $\frac{62}{w}$

w = $\frac{62}{6.31}$

w = 9.82

Similarly,

tan(39°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

0.81 = $\frac{62}{(x+w)}$

0.81 = $\frac{62}{9.83+x}$

9.82 + x = $\frac{62}{0.81}$

x = 76.56 - 9.82

x = 66.74

What is the simplified form of the expression?

AleksAgata [21]

The answer is: 10 x¹³ y¹⁰ .
__________________________________________________________

1x^8 * 2y^(10) * 5x^5 =

1* 2* 5 * x^8 * x^5 * y^(10) =

10 * x^(8+5) * y^(10) =

10 * x^(13) * y^(10) = 10 x^(13) y^10 ; write as:
_______________________________________________
10 x¹³ y¹⁰ .

Step-by-step explanation:

So the general formula for compound interest is $A = P(1+\frac{r}{n})^{nt}$ where r is the interest rate, t is the time in years, and n is the amount of compounds per year. So plugging in the values for both equations you'll get
