4/5 of the original amount at the start of the month will remain. The amount at the start of every month will change. Thus:
an = 4/5 (an-1) ; where a1 = 500.

A taxi charges a flat rate of R10, and an additional cost of 30 cents per kilometer. If you have

Maslowich

Step-by-step explanation:

so, just by getting into the taxi we have to pay R10.

that leaves us 22 - 10 = R12 for the actual trip.

30 cents per kilometer.

so, how many units of 30 cents are there in R12 ? that is the number of kilometers we can go.

R12 = 1200 cent (right ?)

1200 / 30 = 120 / 3 = 40

so, we can travel 40 kilometers for that money.

What's 2sin(2theta)=1? Need it for webassign.

lutik1710 [3]

<em>Solve: </em> $2sin(2x) = 1$

Divide both sides by 2.
$sin(2x) = \frac{1}{2}$

Take the sine inverse of both sides:
$2x = sin^{-1}(\frac{1}{2})$
$2x = \frac{\pi}{6}, \frac{5\pi}{6}, 0 \leq x \leq 2\pi$
$x = \frac{\pi}{12}, \frac{5\pi}{12}$

But we know there are more solutions if we extend the domain. In fact, there are infinitely more solutions since the domain of sine is all real x values.
Thus, we can develop a general solution:

For every $\pi$ units, there is another solution for both $\frac{\pi}{12}$ and $\frac{5\pi}{12}$

General solutions:
$x = \pi n + \frac{\pi}{12}, n \in \mathbb{Z}$
$x = \pi n + \frac{5\pi}{12}, n \in \mathbb{Z}$
