Answer:
Step-by-step explanation:
(cos 4a*cos 2a+sin 4a*sin 2a)/sin 4a
=[cos (4a-2a)]/sin 4a
=(cos 2a)/sin 4a
=(cos 2a) /(2 sin 2a cos 2a)
=1/(2 sin 2a)
=1/2 csc 2a
After factor simplification of the polynomial, The answer is D
4.5 / 2 = 2.25cm radius for the smaller circle
3.14 (pi) × 2.25² = 15.89625cm²
10.5 / 2 = 5.25cm radius for the larger circle
3.14 × 5.25² = 86.54625cm²
86.54625 - 15.89625 = <span>70.65cm</span>²
The answer is 70.7cm².
Answer:
choice #3) similar by SSS
The corresponding sides do have the correct ratios.
Ok. So… Let's see if I can solve this one.
So since they wanted 4.2% out of the 640,000 Abdull makes, we can move the decimal(4.2%) to the left twice. Which will get .042 . The afterword-that will allow us to multiply 640,000 dollar with .042 . Which mean Adbull has receive 26,880 cash that year.
Answer for “A” = 26,880
Ok so his annual salary plus his commission. That means his 400 dollar (per month) plus the amount on the sales commission. Which mean… 400 dollar(Monthly) plus 26,880 dollars. Which will get us 27,280
A = 26,880
B = 27,280
(Im not sure about answer B because Im not sure if they are talking about yearly price for both or monthly payment for 400 dollar plus the monthly commission.) But overall, their,you have your answer.
