Answer: Distance per revolution, 5. Slope, 5x

Step-by-step explanation: The distance per revolution would simply be 10/2, since there are 10 revolutions per 2 minutes. The slope would be the same, 10/2=5. Hope this helps! (Could I please have brainliest?)

Find the x-values that are solutions of the equation 5cot^2x-15=0

julia-pushkina [17]

First solve for the trig function 'cot'
$cot^2 x = \frac{15}{5} = 3$

Next take the sqrt of both sides (include plus/minus)
$cot x = \pm \sqrt{3}$

Now take reciprocal of both sides, this will change trig function to 'tan'
(cot = 1/tan)

$tan x = \pm \frac{1}{\sqrt{3}} = \pm \frac{\sqrt{3}}{3}$

Finally use the unit circle or inverse tan on your calculator to find x.
There will be 4 solutions, one for each quadrant.

$x = \frac{\pi}{6}, \frac{5\pi}{6}, \frac{7\pi}{6}, \frac{11\pi}{6}$

If f(x) = 3x and g(x)=2x, what is (g o f)(x)? 5x 5x2 6x 6x2

eduard

If you would like to solve (g ° f)(x), you can calculate this using the following steps:

(g ° f)(x) = g(f(x))

(g ° f)(x) = g(f(x)) = g(3x) = 2 * 3x = 6x

The correct result would be 6x.
