Help.... and thanks

Mathematics
1 answer:
Archy [21]4 years ago
6 0

Answer:

π

Step-by-step explanation:

The *period* of a function is the length it takes before it repeats. Usually, the period of the sine function is 2π; it takes a full rotation around the unit circle for it to repeat. When we replace the input x with -2x, this does a few things:

- Changes the rotation direction

- Makes the rotation go twice as fast

If we rotate around the unit circle twice as fast, it’ll take us half of 2π, or just π to complete a cycle.

Calculate the insurance costs.

You really just need the little table they provide to figure this one out, but here we go!
<span>First, you must find what class the person falls under. For this, it would be Class 3 since it is used for business purposes, but no male under 25 has driven it. You then find the premium for 100/300 under class 3, which is $549.70 and the property damage of 25,000 (The 25 in 100/300/25 means the damage in thousands), which is $98.20 and add the two together. So the total premium would be $647.90 in total annual premium.</span>
