Write the product as a sum. 17 sin (x/2)cos(x/4)

Mathematics
1 answer:
Korolek [52]3 years ago
4 0

Answer:

  \dfrac{17}{2}\sin{\dfrac{3x}{4}}+\dfrac{17}{2}\sin{\dfrac{x}{4}}

Step-by-step explanation:

The appropriate identity is ...

  \sin{\alpha}\cos{\beta}=\dfrac{1}{2}(\sin{(\alpha+\beta)}+\sin{(\alpha-\beta)})

Filling in α=x/2 and β=x/4, we get ...

  17\sin{(x/2)}\cos{(x/4)}=\dfrac{17}{2}(\sin{(x/2+x/4)}+\sin{(x/2-x/4)})\\\\=\dfrac{17}{2}\sin{\dfrac{3x}{4}}+\dfrac{17}{2}\sin{\dfrac{x}{4}}

Sheri's brother gave Sam his collection of stamps when she left for college. At that
pychu [463]

Answer: $70 per year.

Step-by-step explanation:

Let's say that x is the number of years that has passed and y is how much the stamp is worth.

So we know that in zero years the stamp was worth $420 because that is the time Sheri gave her brother Sam the stamp. That could bring up the coordinates  (0,420) .

Now we know that in 8 years it was worth $980 and that could be the coordinates (8,980)

To find the rate of change we need to find the different between the y value and divide it by the difference in the x values.

420 - 980 = -560

 0-8 = -8

-560/-8 = 70

The rate of change is 70 which means that it grew by $70 every year.
