3 csc^2(2x) + 2 cosec 2x = 1-cot^2(2x)

asambeis [7]

I am assuming you want to solve for x:-

Now cosec^2 2x = 1 - cot^2 2x so the equation becomes

3 cosec^2(2x) + 2 cosec 2x = cosec^2 2x

2 cosec^2 2x + 2 cosec 2x = 0

2 cosec 2x ( cosec 2x + 1) = 0

so 2 cosec 2x = 0 or cosec 2x = -1

cosec 2x = 0 or cosec 2x = -1

cosec 2x = 0 is indeterminate so we ignore the first one

cosec 2x = -1 can be written as 1 / sin 2x = -1

so sin 2x = -1

giving 2x = 270 degrees

Therefore x = 135 degrees answer

The lograthmic function, lograthmic fu

$y=\log_4x$

To find:

a) Rewrite the function in exponential form.

b) For each given value of y, find the value of x to complete the ordered pair.

c) The graph of the function.

Explanation:

It is given that,

$y=\log_4x$

a) Since,

It is known that,

$\begin{gathered} y=\log_ax \\ \Rightarrow x=a^y \end{gathered}$

Then,

$x=4^y$

Hence, the exponential form of the function is,

$x=4^y$

b) Also,

For y = -2,.

The value of x is given by,

$\begin{gathered} \\ \Rightarrow x=4^{-2} \\ \Rightarrow x=\frac{1}{4^2} \\ \Rightarrow x=\frac{1}{16} \end{gathered}$

Hence, the ordered pair is (1/16, -2).

For y = -1,

$\begin{gathered} x=4^{-1} \\ x=\frac{1}{4} \end{gathered}$

Hence, the ordered pair is (1/4, -1).

For y = 0,

$\begin{gathered} x=4^0 \\ x=1 \end{gathered}$

Hence, the ordered pair is (1, 0).

For y = 1,

$\begin{gathered} x=4^1 \\ x=4 \end{gathered}$

Hence, the ordered pair is (4, 1).

For y = 2,

$\begin{gathered} x=4^2 \\ x=16 \end{gathered}$

Hence, the ordered pair is (16, 2).

c) Also, the graph of the given function is,

Find the measurement of HI

Murljashka [212]

Answer: 15

Explanation: the triangle to the right is a dial action of the smaller triangle, therefore the triangles are similar. Since the sides of both triangles are corresponding if the corresponding side to JI is 5, and JI is 25 then it is a dialation by a multiple of 5. So since the corresponding side to HI is 3, HI is 15
