2. Solve for x. Round answer to the nearest tenth. *

slavikrds [6]

Answer:

x ≈ 7.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos22° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{8}$

Multiply both sides by 8

8 × cos22° = x, thus

x ≈ 7.4 ( to the nearest tenth )

Find the value of questions

Zolol [24]

Answer:

The simplified expression is:

$\frac{3^9y}{2\times \:81}=\frac{243y}{2}$

Step-by-step explanation:

Given the expression

$\frac{3^9\times \:y}{2\times 81}$

solving the expression

$\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}$

$=\frac{3^9y}{3^4\times \:2}$ ∵ $162=3^4\times \:2$

$=\frac{3^5y}{2}$ ∵ $\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}$

$=\frac{243y}{2}$ ∵ $3^5=243$

Therefore, the simplified expression is:

$\frac{3^9y}{2\times \:81}=\frac{243y}{2}$
