THIS IS THE LAST QUESTION IDK HOW DO SOLVE IT :(

harkovskaia [24]

Answer:

6 laps.

Step-by-step explanation:

On Monday she runs 2x + 8 miles, where x miles = the length of the trail.

On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so

2x + 8 = 4x + 4

4 = 2x

x = 2 miles which is the length of the trail.

So each day she runs 4(2) + 4 = 12 miles.

So on Saturday she runs 12/ 2 = 6 laps.

Sin^2(x/2)=sin^2x <br> Find the value of x

Veronika [31]

$\sin^2\dfrac x2=\sin^2x$
$\dfrac{1-\cos x}2=1-\cos^2x$
$1-\cos x=2-2\cos^2x$
$2\cos^2x-\cos x-1=0$
$(2\cos x+1)(\cos x-1)=0$
$\implies\begin{cases}2\cos x+1=0\\\cos x-1=0\end{cases}$ $\implies\begin{cases}\cos x=-\frac12\\\cos x=1\end{cases}$

The first case occurs in $0\le x$ for $x=\dfrac{2\pi}3$ and $x=\dfrac{4\pi}3$ . Extending the domain to account for all real $x$ , we have this happening for $x=\dfrac{2\pi}3+2n\pi$ and $\dfrac{4\pi}3+2n\pi$ , where $n\in\mathbb Z$ .

The second case occurs in $0\le x$ when $x=0$ , and extending to all reals we have $x=2n\pi$ for $n\in\mathbb Z$ , i.e. any even multiple of $\pi$ .
