Step-by-step explanation:
The answer is D)
b^10/b^2
= b^10-b^2 = b^8
hope this helps.pls like and follow if you understand.
thanks:-):-)
No because then somewhere in the problem you could multiply once more. like if u had 234 as ur answer, but had 2 as a remainder, u would change the 4 to a 5 (don't know if tht math is right, but the main idea of it is right)
Answer:
3
Step-by-step explanation:
374274 =3.74274 x 100000=3.74272x 10^5
Sin A = opposite / hypotenuse
If angle A is in the first quadrant, that means both x and y coordinate are positive.
Now you can draw triangle. Since sinA = 1/3, opposite side may be 1, so then hypotenuse side must be 3.
Now you can use Pythagorean Theorem to solve for the length of adjacent side:
a² + b² = c²
1 + b² = 9
b² = 8
b = 2√2
So adjacent side is 2√2.
So now we can solve for cosA:
cosA = adjacent / hypotenuse = 2√2 / 3
Final answer: 2√2 / 3
