Answer:

$x = \sqrt{\frac{7}{2} }$

Step-by-step explanation:

<u><em>Explanation</em></u>

From given graph

AC = √7

Given angle ∝ = 45°

$cos\alpha = \frac{adjacentside}{Opposite side}$

$cos45 = \frac{x}{\sqrt{7} }$

$\frac{1}{\sqrt{2} } = \frac{x}{\sqrt{7} }$

$x = \frac{\sqrt{7} }{\sqrt{2} }$

$x = \sqrt{\frac{7}{2} }$

x = 1.8708

Suppose y varies inversely with x, and y = 6 when x = 3. Find x when y = 12.

slava [35]

Answer:

1.5

Step-by-step explanation:

$y \: \alpha \: \frac{1}{x}$

y = k ÷ x

yx = k

y = 6 , x = 3

6 • 3 = k

18 = k

when y = 12 , x = ?

yx = k

12x = 18

x = 18÷12

x = 3/2

x = 1.5
