Part of question :
(x-10)^2+(y-10)^2=100
(16-10)^2+(18-10)^2=100
Answer:
Yes, equation of circle is true
Step-by-step explanation:
(x-10)^2+(y-10)^2=100
(16-10)^2+(18-10)^2=100
100=100
plugging the coordinates into the equation of the circle, we observe that the equation is true since both sides of the equation are equal(value on both sides of the equal sign are same). This wouldn't be true if for instance the left side of the equation evaluated to ≠100. Therefore we can conclude that the rose bush lies on circle since the equation is true
Answer:
The correct prove will be:
Step-by-step explanation:
Multiply and Divide by 
= 
⇒ Let 
= Ф and 7Ф = 
= sin2Ф sin3Ф sin5Ф ÷ 2cosФ
= 1/2(2sin2Фsin5Ф)sin3Ф ÷ 2cosФ
= (cos3Ф - cos7Ф) sin3Ф ÷ 4cosФ
= 1/2(2cos3Ф sin3Ф) ÷ 4cosФ ∵cos7Ф = 0
= sin6Ф ÷ 8cosФ
= sin(7Ф - Ф) ÷ 8cosФ
= (sin7ФcosФ - cos7ФsinФ) ÷ 8cosФ ∵sin7Ф = 1
= cosФ ÷ 8cosФ
= 1/8
Hence, The correct prove will be:
Keywords: prove, sinФ, cosФ

No, because if the angles are the same the length is the same too. It is a scalene, obtuse triangle if you need that as well.
Answer: 4
Step-by-step explanation: Slopes that are perpendicular to each other are opposite reciprocals. So take the opposite of the sign, negative or positive. Then flip the numerator and the denominator. -1/4 goes to +1/4 goes to +4. Hope this helps!
Hope this helps but the answer is A.(-5,2)
