nika2105 [10]

Answer:

BC ≈ 8.9 units

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos36° = \frac{adjacent}{hypotenuse} = \frac{BC}{AB} = \frac{BC}{11} ( multiply both sides by 11 )

11 × cos36° = BC , then

BC ≈ 8.9 ( to the nearest tenth )

The function f(3) = 50.000(0.975)", where x represents the underwater
valentina_108 [34]

Answer:

  316 lumens/m²

Step-by-step explanation:

We assume your intensity function is ...

  f(x) = 50,000(0.975^x) . . . . x meters below the surface

__

Use 200 for x and do the arithmetic.

  f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²

Find the volume of the cylinder.
KiRa [710]

Answer:

  12π ≈ 37.7 cubic centimeters

Step-by-step explanation:

The volume of the cylinder can be found using the appropriate formula.

__

<h3>dimensions</h3>

The cylinder is marked as having a diameter of 4 cm, and a height of 3 cm. The radius of the cylinder is half the diameter:

  r = d/2

  r = (4 cm)/2 = 2 cm

__

<h3>formula for volume</h3>

The formula for the volume of a cylinder is ...

  V = πr²h . . . . . . where r is the radius and h is the height

Using the dimensions given, we find the volume to be ...

  V = π(2 cm)²(3 cm) = π(4 cm²)(3 cm) = 12π cm³

Written as a decimal, the volume is about ...

  12π cm³ ≈ 37.70 cm³ . . . . volume of the cylinder

_____

<em>Additional comment</em>

You probably noticed that we used the units in the formula along with the numbers. Units abbreviations can be manipulated algebraically the same way any other variable can be:

  x · x = x²

  cm · cm = cm²

Computing the volume in more steps, we have ...

  V = π(2 cm)²(3 cm)

  = π(2 cm)(2 cm)(3 cm) . . . . expanding the square term

  = π(2)(2)(3)(cm)(cm)(cm) . . . . we can rearrange the factors of a product

  = π(12)(cm³)

  = 12π cm³
