Solve the equation on the interval [0,2π). cos^4x=cos^4xcscx
Alisiya [41]
\bf cos^4(x)=cos^4(x)csc(x)\\\\
-----------------------------\\\\
cos^4(x)=cos^4(x)\cfrac{1}{sin(x)}\implies cos^4(x)=\cfrac{cos^4(x)}{sin(x)}
\\\\\\
cos^4(x)sin(x)=cos^4(x)\implies cos^4(x)sin(x)-cos^4(x)=0
\\\\\\
cos^4(x)[sin(x)-1]=0\to 
\begin{cases}
cos^4(x)=0\to x=cos^{-1}(0)\\
----------\\
sin(x)-1=0\\
sin(x)=1\to x=sin^{-1}(1)
\end{cases}

\bf \measuredangle x = cos^{-1}(0)\implies \measuredangle x = 
\begin{cases}
\frac{\pi }{2}\\\\
\frac{3\pi }{2}
\end{cases}
\\\\\\
\measuredangle x=sin^{-1}(1)\implies \measuredangle x=\frac{\pi }{2}

M,H, and G have written more than a combined total of 22 articles. H has written 1/4 as many as M. G has written 3/2 as M. Write
Natalka [10]

Missing part of the question:

Write an inequality to determine the number of articles, M could have written for the school newspaper.

Answer:

The inequality: 11M > 88

The solution: M > 8

Step-by-step explanation:

Given

From the question, we have the following parameters:

M + H + G > 22

H = \frac{1}{4}M

G = \frac{3}{2}M

Required

Determine the inequality to solve for M

Substitute the values for H and G in the inequality:

M + H + G > 22

M + \frac{1}{4}M + \frac{3}{2}M > 22

Multiply through by 4

4(M + \frac{1}{4}M + \frac{3}{2}M) > 22*4

4M + M + 6M > 88

11M > 88

Divide both sides by 11

M > 8

What is the range of y=log^2(x-6)
Marysya12 [62]

Answer:

y\geq 0 or [0, \infty)

Step-by-step explanation:

By definition the function

y = log (x) has a domain of x> 0.

Since the function is not defined for the values of x negative or equal to zero.

The range of this function is all the real numbers.

Since y when 0 and y\geq0 when 1\leq x

In this case we have the function y = log ^ 2 (x-6)

Therefore since the log function is squared then its range is now y\geq 0
