3cot^(2 )x-1=0<br><br> Pls Help
Elina [12.6K]

Answer:

x=\frac{\pi }{6} ,\frac{7\pi }{6}

Step-by-step explanation:

3*cot^2x-1=0\\\\3*cot^2x=1\\\\cot^2x=\frac{1}{3} \\\\cot(x)=\sqrt{\frac{1}{3} } \\\\cot(x)=\frac{1}{\sqrt{3} } \\\\\frac{1}{tan(x)}=\frac{1}{\sqrt{3} } \\\\tan(x)=\sqrt{3} \\

x=tan^-1(\sqrt{3})

It has to be in Quadrant 1  \frac{+}{+} =+ or 3 \frac{-}{-}=+ for positive.

x=\frac{\pi }{6} ,\frac{7\pi }{6}

Unless that incorrect due to tan(x) range is -\frac{\pi }{2} \leq x\leq \frac{\pi }{2}. Then the only answer is x=\frac{\pi }{6}

The two-way table shows the distribution of book style to genre. Miguel claims that given that the book is paperback (PB) does n
Solnce55 [7]

The claim of Miguel is correct, as the two events are independent because P(NF|PB) = P(NF).

<h3>What is conditional probability?  </h3>

The conditional probability is the happening of an event, when the probability of occurring of other event is given.

P(A|B)=\dfrac{P(A\cap B)}{P(B)}

The probability of event A, given that the event B is occurred.

Independent events are those events whose occurrences do not depend on the other events.

The two-way table shows the distribution of book style to genre is given as,

The first column has entries paperback, hardcover, total.

The second column is labeled Fiction with entries     20,   10,   30.

The third column is labeled nonfiction with entries    60,   30,  90.

The fourth column is labeled total with entries           80,  40,  120.

Miguel claims that given that the book is paperback (PB) does not affect the outcome that the book is nonfiction (NF).

Suppose that two events are denoted by A and B. They are said to be an independent event if and only if:

P(A \cap B) = P(A)P(B)

Put the values as,

\dfrac{60}{120}=\dfrac{80}{120}\times\dfrac{90}{120}\\\dfrac{1}{2}=\dfrac{1}{2}

As both the values are equal. Thus, the claim of Miguel is correct because the two events are independent because P(NF|PB) = P(NF).

Find the average rate of change of each function over the interval [0, 2]. Match each representation with its respective average
marishachu [46]
Average rate of change over interval [a,b]: r=[f(b)-f(a)]/(b-a)
In this case the interval is [0,2], then a=0, b=2
r=[f(2)-f(0)]/(2-0)
r=[f(2)-f(0)]/2

1) First function: h(x)
r=[h(2)-h(0)]/2
x=2→h(2)=(2)^2+2(2)-6
h(2)=4+4-6
h(2)=2
x=0→h(0)=(0)^2+2(0)-6
h(0)=0+0-6
h(0)=-6
r=[h(2)-h(0)]/2
r=[2-(-6)]/2
r=(2+6)/2
r=(8)/2
r=4

2) Second function: f(x)
A function, f, has an
x-intercept at (2,0)→x=2, f(2)=0
and a y-intercept at (0,-10)→x=0, f(0)=-10
r=[f(2)-f(0)]/2
r=[0-(-10)]/2
r=(0+10)/2
r=(10)/2
r=5

3) Third function: g(x)
r=[g(2)-g(0)]/2
From the graph:
g(2)=6
g(0)=2
r=(6-2)/2
r=(4)/2
r=2

4) Fourth function: j(x)
r=[j(2)-j(0)]/2
From the table:
x=2→j(2)=-8
x=0→j(0)=4
r=(-8-4)/2
r=(-12)/2
r=-6

Answer:
Pairs
1) h(x)     4
2) f(x)      5
3) g(x)     2
4) j(x)     -6
