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

Given:

The equation is

\dfrac{1}{3}x=\dfrac{1}{5}

To find:

The coefficient and reciprocal.

Solution:

We have,

\dfrac{1}{3}x=\dfrac{1}{5}

Here, \dfrac{1}{3} is multiplied with x.

So, the coefficient of x is \dfrac{1}{3}.

To find the reciprocal, we need to interchange numerator and denominator of a fraction.

So, the reciprocal of \dfrac{1}{3} is \dfrac{3}{1}=3

Therefore, the reciprocal is 3.

If the line in the graph is shifted up two units which is the equation of the new line
anastassius [24]

Answer:

f(x) + 2.

Step-by-step explanation:

Example:

If we have say f(x) = x + 1 then 2 units will be added to f(x) when it is moved up 2 units.

So the equation of this line will be f(x) + 2 which in this example is

x + 1+ 2.

The new function is  x + 3.
