a boat is traveling at an average speed of 15 meters per second. how many kilometers per minute is the boat traveling?

lukranit [14]

We know that 1 meter is 0.001 km and that 1 minute is 60 seconds.
To transform 15m/s we into km/min we have to multiply 15 by 0.001 and multiply it by 60.
$15*0.001*60=0.0015*60=0.09 km/min$ - its the answer

Answer:

Graph B shows function f of x equals 4 multiplied by 3 to the power of negative x.

Step-by-step explanation:

$f(x) = 4(3)^{-x}$ is the value 4 times three raised to the negative x. Graph B is the best representation.

Answer:

$(b)\\\tan x, \cot x$

Step-by-step explanation:

Given

trigonometric function is

$\dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}$

Applying trigonometric formulae

$\Rightarrow \cos C-\cos D=-\sin (\dfrac{C+D}{2})\sin (\dfrac{C-D}{2})\\\\\Rightarrow \sin C+\sin D=\sin (\dfrac{C+D}{2})\cos (\dfrac{C-D}{2})$

$\Rightarrow \dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}=\dfrac{2\sin 3x\cdot \sin x}{2\sin 3x\cdot \cos x}\\\\\Rightarrow \dfrac{\sin x}{\cos x}=\tan x$

option (b) is correct

$\Rightarrow \dfrac{\cos 2x+\cos 4x}{\sin 2x-\sin 4x}=\dfrac{2\cos 3x\cdot \cos x}{2\cos 3x\cdot \sin (-x)}=-\cot x$
