Answer: 84.9
Step-by-step explanation:
Model's equation: y=1.11x^2
Since y = 2000
y = 1.11x^2
2000 = 1.11x^2
x^2 = 2000/1.11
x^2 = 1801.8
x = 42.45
Diameter of the smallest circle will be:
= 2x
= 2 × 42.45
= 84.9
Use Hooke's law... (just kidding)
Break down each force vector into horizontal and vertical components.
The resultant force is the sum of these vectors,
and has magnitude
The closest answer is D.
Answer:
$20.45
Step-by-step explanation:
Since the Bayside Bugle charges $18 for the first 20 words and there is more than 20 words in the ad you take 27-20 and you get 7 additional words.
Now we know that we already have to pay $18 for the first $20 words.
Since we have 7 additional words we multiply that by 0.35 cents and you get $2.45.
Next we add up our two numbers (2.45+18) we get the total of $20.45 fro a 27-word ad.
I hope this helps :)
5/6 and 2/9......least common denominator is 18
so 5/6 = 15/18 and 2/9 = 4/18
1/12 and 3/8...least common denominator is 24
so 1/12 = 2/24 and 3/8 = 9/24
5/9 and 2/15...least common denominator is 45
so 5/9 = 24/45 and 2/15 = 6/45
This system can be a bit tricky unless you write it out:
(2n + 2)(2n - 2) ~ First you have to take one variable and multiply it to each of the other two variables, like:
2n * 2n ~ And:
2n * -2 ~ This gives you:
4n^2 - 4n
Now we do this with the other:
2 * 2n
2 * -2
4n - 4
Now we combine them both while adding like terms:
4n^2 - 4
Therefore your answer is: A. 4n^2 - 4
(This is due to how when having the positive 4n subtracted by the negative it cancels it out. Leaving us with the remaining two terms left.)
I hope this helps, have a great rest of your day! ^ ^
