Help rn please it’s not 16 or 12!!’
natali 33 [55]

Answer:

See below.

Step-by-step explanation:

7) 10 x [(7² + 3) - 9]

= 10 x [52 - 9]

= 10 x 43

= 430

9) {[(66 / 11) + 3] x 2}

= [6 + 3] x 2

= 9 x 2

= 18

11) {[(18 - 3) + 3²] - 14} x 3

= {[24] - 14} x 3

= 10 x 3

= 30

The equation to model the situation is \mathbf{y = \dfrac{k}{x^2}}. The constant for the variation is 2250.

<h3>What is the intensity of light?</h3>

The intensity of light from a lantern varies inversely to the square of the distance from the lantern.

From the given information:

  • Let y be the intensity of light, and
  • x be the distance from the lantern

Then:

\mathbf{y \alpha \dfrac{1}{x^2} }

\mathbf{y = \dfrac{k}{x^2} }   here, k = constant.

2.

If y = 90 W/m² when the distance x = 5m

Then:

\mathbf{90 = \dfrac{k}{(5)^2}}

k = 90 × 25

k = 2250

c.

The equation to model the situation by using the constant variation is:

\mathbf{y = \dfrac{2250}{x^2}}

d.

If the light intensity y = 40, then x is determined as:

\mathbf{40 = \dfrac{2250}{x^2}}

\mathbf{x = \sqrt{\dfrac{2250}{40}}}

x = 7.5 m

e.

The light is needed in (225 × 1000)m = 225000 km of illumination.

f.

The lantern required for the new light estimation is:

y = 2250/225000

y = 0.01 intensity

Therefore, we can conclude that to get an intensity of 1 W/m², we need to put 100 lanterns.
