A boat that is 2 miles offshore from a lighthouse is moving parallel to the coast. The light on the lighthouse is turning at the

Papessa [141]

Answer:

speed of light movement when boat is 1 mile from light house is 0.029 miles/sec

Step-by-step explanation:

Given data:

distance of boat from light house is 2 miles

rate of turning of light is 100 degree per minute

w = 100 degree/min

$w = 100 \times \frac{\pi}{180} rad/min$

w = 1.745 rad/min

w = 0.0290 rad/sec

speed of movement of light $v = w\times r$

$v = 0.029 \times 1 = 0.029 mile/sec$

thus speed of light movement when boat is 1 mile from light house is 0.029 miles/sec

What is the value of x

zaharov [31]

We use the Pythagorean theorem here, because we have the two sides and a right angle between them, so we calculate the hypotenuse like this:

x^2 = 6^2 + 8^2

x^2 = 36 + 64

x^2 = 100

x = square root of 100

x = 10

The correct answer is B.10.

What is the percent of increase for a population that changed from 438,000 to 561,000?

BARSIC [14]

New number - original number

561,000 - 438,000 = 123,000.

Increased number divided by the original number

123,000 ÷ 438,000 = 0.28

Multiply by 100

0.28 x 100 = 28%

The percentage increase would be 28%
