Csc x= -√2 for π≤x≤3π/2
love history [14]

Answer:

A

Step-by-step explanation:

We can write this as Sinx by "flipping" the -\sqrt{2}.

So we will have:  Sin(x)=-\frac{1}{\sqrt{2} }

From basic trigonometry, we know the value of  \frac{1}{\sqrt{2}}  of sine is of the angle \frac{\pi}{4}

<em>But when is sine negative? </em>Either in 3rd or 4th quadrant. But the answer has to be between 0 and  \frac{3\pi}{2}, <em>so we disregard 4th quadrant.</em>

<em />

<em>To get the angle in 3rd quadrant, we add π to the acute angle of the first quadrant (which is π/4 in our case).</em><u><em> Thus we have:</em></u>

\frac{\pi}{4}+\pi\\=\frac{\pi +4\pi}{4}\\=\frac{5\pi}{4}

A is the right answer.

Which symbol makes the comparisons true ? Complete the comparison -6 ? 3
Usimov [2.4K]
<h3>Hello!</h3>

======================================

Negative numbers are always less than positive ones.

Do you remember the symbol for "less than"? That's right, "<" :)

Hence,

-6<3

Because

-6 is negative (the - sign tells us that)

3 is positive

===================================

A man has 10 more dimes than quarters. he has $2.75 how many of each coin does he have?
Anton [14]
5 quarters, 15 dimes

q + 10 = d
0.25q + 0.1d = 2.75

0.25q + 0.1(q + 10) = 2.75
0.25q + 0.1q + 1 = 2.75
0.35q = 1.75
q = 5

Check:

0.25(5)+ 0.1(15)= 2.75
1.25 + 1.5 = 2.75
2.75 = 2.75 :)
