Explain how to find the exact value of sin(570°).

The precise value that is given by sin 570° would be:

Given that,

sin 570°

To solve,

We will employ the degree to radian conversion,

θ = θ° × π/180°

To find,

° ° × π°

Since radian π

∵

Thus, the value of sin 570° would be .

-1/2

Step-by-step explanation:

Start by subtracting 360° from 570°, obtaining 210°.  These two angles share the same terminal side, located in Quadrant III, and thus share their trig function values.

Similarly, subtract 180° from 210°, obtaining 30°.  In Quadrant III, the opposite side is -1, the adjacent side is -√3/2 and the hypotenuse is 2.

The sine of 570° is thus opp/hyp, or -1/2.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
