Answer:

-0.2

Step-by-step explanation:

Sine and cosine are co-functions.

That means, cos(90-x)=sin(x) or sin(90-x)=cos(x).

So here since cos(90-x)=-0.2, then sin(x)=-0.2.

How are volatility and risk related in an investment ​
AleksAgata [21]

Answer:

Volatility - the measure of how far the price of an investment moves - is sometimes low, sometimes high, but always a natural part of investing. Risk is the likelihood of an investment losing value, adjusted for inflation, over a longer period of time.

a garden snail travels about 2 3/5 feet in 1 minute. At that speed about how many hours would it take the snail to travel 350 fe
SCORPION-xisa [38]
Make the fraction a decimal.
3÷5= 0.6
Now add the whole number and that makes it 2.6
That's how long he travels in one minute. There are 60 minutes in an hour so multiply it by 60 and see if that gets you close to 350.
60x2.6= 156
Now let's add one more hour.
156+156= 312
That's pretty close to what we want. Now, keep adding minute at a fast rate to get where you need to be.
14x2.6=36.4
312+36.4= 348.4
348.4+2.6=351
So two hours and fourteen minutes

QUESTION EIGHT: 2690

QUESTION NINE: 120

QUESTION ELEVEN: 12.5

QUESTION FOURTEEN: 24

<u>Step-by-step explanation:</u>

8.

may 3rd -> july 15th = 73 days

500*0.06 = 30

30 = how much he makes in one day (so he has 530 after 1 day)

30*73 = 2190

500 + 2190 = 2690

9.

210/7 = 30

1% for 3 years = 30

1% for 1 year = 10

100% for 1 year = 1000

2000*0.06 = 120

11.

54,000*0.08 = 4320

54,000/4320 = 12.5

14.

5000*6.26% = 312.5

7500/312.5 = 24
