Find y. Round to the nearest tenth: 290 500 ft y X y = [ ? ]ft

hjlf

Answer:

y = 242.4

x = 437.3

First find the inner angle:

90° - 29°

61°

[ given hypotenuse = 500 ft ]

using sine rule:

$\sf sin(x)= \dfrac{opposite}{hypotensue}$

$\hookrightarrow \sf sin(61)= \dfrac{x}{500}$

$\hookrightarrow \sf x=sin(61)*500$

$\hookrightarrow \sf x=437.3$

using pythagoras theorem:

a² + b² = c²

y² + (437.3)² = 500²

y = √58760.1

y = 242.4

Suppose y varies inversely with x. Write an equation if y=7 when x=-4

luda_lava [24]

Answer:

y = -28 ÷ x

Step-by-step explanation:

The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.

So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x

K = constant, we have to work this out

7 = k ÷ -4

7 × - 4 = k

k = - 4 × 7

k = -28

k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x
