Hello, precalc, need help on finding csc

Ainat [17]

Recall the double angle identity for cosine:

$\cos(2x) = \cos^2(x) - \sin^2(x) = 1 - 2 \sin^2(x)$

It follows that

$\sin^2(x) = \dfrac{1 - \cos(2x)}2 \implies \sin(x) = \pm \sqrt{\dfrac{1-\cos(2x)}2} \implies \csc(x) = \pm \sqrt{\dfrac2{1-\cos(2x)}}$

Since 0° < 22° < 90°, we know that sin(22°) must be positive, so csc(22°) is also positive. Let x = 22°; then the closest answer would be C,

$\csc(22^\circ) = \sqrt{\dfrac2{1-\cos(44^\circ)}} = \sqrt{\dfrac2{1-\frac5{13}}} = \dfrac{\sqrt{13}}2$

but the problem is that none of these claims are true; cot(32°) ≠ 4/3, cos(44°) ≠ 5/13, and csc(22°) ≠ √13/2...

The temperature was -4°F this morning. If the temperature dropped 7°F, what is the temperature now?

DiKsa [7]

Answer:

-11°F

Step-by-step explanation:

The temperature was -4° in the morning. The temperature dropped 7° later.

Subtract 7 from -4.

$-4-7=\boxed{-11}$

The temperature should be -11°F.

Hope this helps.

Simply using exponents .Then find the products .

aksik [14]

Answer:

$\sqrt[7]{b^{15}}$

Step-by-step explanation:

=> $b^2*\sqrt[7]{b}$

=> $b^2*b^{1/7}$

Where bases are same, powers are to be added.

=> $b^{2+(1/7)}$

=> $b^ {14+1/7}$

=> $b^{15/7}$

=> $\sqrt[7]{b^{15}}$
