Option D:
A = 1, B = –3 and C = 4.
Solution:
Given equation is x – 3y + 4 =0.
General equation of a line format:
<em>Ax + By + C = 0</em>
<u>To identify A, B and C in the given equation:</u>
x – 3y + 4 =0 is a equation of a line which is in the form of Ax + By + C = 0.
That is,
The coefficient of x is A ⇒ A = 1
The coefficient of y is B ⇒ B = –3
The constant term is C ⇒ C = 4
A = 1, B = –3 and C = 4.
Hence Option D is the correct answer.
The √125 can be factored out to 25 and 5 then 25 can be factored out to 5 and 5. Then you pair up the numbers, you have a pair of 5's and a 5 left over. So the pair of 5's goes inside the radical as √5 and on the outside of the radical you have 5×3. So 3√125≈15√5.
Answer:
i think the answer is 125.66 (or 125.6 if you use 3.14 as pi)
Step-by-step explanation:
First find the area of the blue circle by multiplying pi times the radius squared to get 380.13 (or 379.94 if multiplied 3.14)
Then find the area of the orange circle by doing the same thing to get 254.47
(or 254.34 if multiplied by 3.14)
finally subtract 380.13-254.47 to get 125.66.
(or 125.6)
2 OVER 8 AND 4 OVER 16 AND 1 FOURTH
Yes, in order to be a real number, it must not contain the number i, which is an imaginary number, represented by √-1. Since 9/10 is equal to .9, there is no i in the number, meaning it is a real number.
