ANSWER
EXPLANATION
The given expression is
We regroup the numerical parts to get;
Now let us simplify the negative numbers.
We now subtract 19 from 42 to get;
We can't simplify further
Hence the simplest form is:
Answer:
•cos(s+t) = cos(s)cos(t) - sin(s)sin(t) = (-⅖).(-⅗) - (√21 /5).(⅘) = +6/25 - 4√21 /25 = (6-4√21)/25
•cos(s-t) = cos(s)cos(t) + sin(s)sin(t) = (-⅖).(-⅗) + (√21 /5).(⅘) = +6/25 + 4√21 /25 = (6+4√21)/25
cos(t) = ±√(1 - sin²(t)) → -√(1 - sin²(t)) = -√(1 - (⅘)²) = -⅗
sin(s) = ±√(1 - cos²(s)) → +√(1- cos²(s)) = +√(1 - (-⅖)²) = √21 /5
This is called scientific notation. To simplify, just do 10 to the 7th (1 with 7 zero's behind it) to get 10,000,000 (10 million) then multiply that by 2.6 to get your final answer:
26 million or 26,000,000
Just so you know, picking a brainliest answer gives YOU back points, and I kind of need the rank upgrade, as it's kind of embarrassing being Ambitious with more than 9 times the amount of points needed and around 7 times the number of brainliest answers.
I think this was ur question Rachel bought 1,500 shares of Cawh Consolidated Bank at a price of $24.85 each. As the price climbed, she sold off parts of her holdings. She sold off 250 shares at $28.32 apiece, she sold 800 of her shares at $33.60 apiece, and she sold off the remainder of her shares at $39.94 apiece. If Rachel's broker charges a commission of $65 per $1,000 of stock bought or sold, how much profit did Rachel make, to the nearest dollar?
I think the answer is 8,859? I don't know what the question was, but I think that's it. Hope this helps. c;
Answer:
840
Step-by-step explanation:
8×6×15=720
5×6×4=120
720+120=840
