A boat is heading towards a lighthouse, whose beacon-light is 139 feet above the
Novay_Z [31]

The horizontal distance between light house and boat is 1588.78 feet approximately.

The figure is given by,

Here, AB  = height of the lighthouse bacon light above the water = 139 feet

Now angle ACB = 5 degree

Let the horizontal distance of light house from the boat = BC = x feet

So by trigonometric function we get,

tan 5 = AB/BC

tan 5 = 139/x

x = 139/tan 5 = 1588.78 (approximately)

Hence the horizontal distance between light house and boat is 1588.78 feet approximately.

Jason wants to fill a cylindrical water tank to its full capacity. He knows that the volume of the tank is equal to the product
almond37 [142]

Answer:

The answer is B ⇒ \sqrt{\frac{V}{15\pi }}=10

Step-by-step explanation:

∵ v = π r² h

∴ r² = \frac{V}{\pi h }

∴ r = \sqrt{\frac{V}{\pi h}}

∵ r = 10 ft and h = 15 ft

∴ 10=\sqrt{\frac{V}{15\pi } }
