Answer:

Below in bold.

Step-by-step explanation:

Nth term an = a1 + d(n - 1)   where a1 = term 1 and d = common difference.

Here a1 = 5 and d = 8-5 = 3.

So an = 5 + 3(n - 1)

15th term a15

=  5 + 3(15 - 1)

= 5 + 42

= 47.

Solve the equation on the interval [0,2π). cos^4x=cos^4xcscx
Alisiya [41]
\bf cos^4(x)=cos^4(x)csc(x)\\\\&#10;-----------------------------\\\\&#10;cos^4(x)=cos^4(x)\cfrac{1}{sin(x)}\implies cos^4(x)=\cfrac{cos^4(x)}{sin(x)}&#10;\\\\\\&#10;cos^4(x)sin(x)=cos^4(x)\implies cos^4(x)sin(x)-cos^4(x)=0&#10;\\\\\\&#10;cos^4(x)[sin(x)-1]=0\to &#10;\begin{cases}&#10;cos^4(x)=0\to x=cos^{-1}(0)\\&#10;----------\\&#10;sin(x)-1=0\\&#10;sin(x)=1\to x=sin^{-1}(1)&#10;\end{cases}

\bf \measuredangle x = cos^{-1}(0)\implies \measuredangle x = &#10;\begin{cases}&#10;\frac{\pi }{2}\\\\&#10;\frac{3\pi }{2}&#10;\end{cases}&#10;\\\\\\&#10;\measuredangle x=sin^{-1}(1)\implies \measuredangle x=\frac{\pi }{2}
