Solve 3cot (2x) =- Route3 for<br> x, 0 = x < 360

ivolga24 [154]

Answer:

x=60,150,240,330

Step-by-step explanation:

$3 \cot(2x) = - \sqrt{3}$

$\cot(2x) = \frac{ - \sqrt{3} }{3}$

Take the arc cot of both sides

$\cot {}^{ - 1} ( \cot(2x) ) = \cot {}^{ - 1} ( \frac{ - \sqrt{3} }{3} )$

$2x = 120$

Remember cotangent has a period of 180 degrees

$2x = 120 + 90(n)$

where n is 0, 1,2,3,4,5.....

Isolate x.

$x = 60 + 90(n)$

where n is 0, 1,2,3,4,5,6.

Keep plugging in integers as long they are in the interval [0,360].

We get

60,150,240,330.

Answer:

Completing the table, we have;

Explanation:

Given the equation;

$y=2x-1$

where y is the output and x is the input.

we were given the outputs 1,3,5.

To get the input for each of the given output let us substitute the output into the equation and solve for x;

$\begin{gathered} \text{for output = 1;} \\ 1=2x-1 \\ 1+1=2x \\ 2=2x \\ x=\frac{2}{2} \\ x=1 \end{gathered}$ $\begin{gathered} \text{for output = 3 ;} \\ 3=2x-1 \\ 3+1=2x \\ 4=2x \\ \frac{4}{2}=x \\ x=2 \end{gathered}$ $\begin{gathered} \text{for output = 5;} \\ 5=2x-1 \\ 5+1=2x \\ 6=2x \\ \frac{6}{2}=x \\ x=3 \end{gathered}$

Therefore, completing the table, we have;
