Hello...
I'm new user here.
Can you teach me how to use brainly? Please, it would bey favour.
I have just downloaded the app and don't know how to use.
At θ = 90°, the equation must evaluate to zero. The only one that does that is the 1st choice ...
r = 2 - 2sin(θ)
824 just add all the sides so 12+12+400+400=824 and in simpler form w2+l2
Answer:
1. y = 1/4 and y = 1/4x+2
2. y - 1 = -x (x + 7) and y = -x and x + y = 3
-------
4. y = 3 and x = 6
5. y = 1/2x + 2 and y + 1 = -2x
6. Slope of <u>AB</u> = 2/3
Slope of BC = -3/2
AB is perpendicular to BC because 2/3(-2/3) = -1
ABC is a right triangle because it contains a right angle
