In general, in polar coordinates (r, ω) = (-r, ω+π), because when you add π radians to an angle you are turning 180 degrees and then need to change the sign of the radius to preserve the original point.
Then (-5, π/4) = (5 , π/4 + π) = (5, 5π/4)
Answer: (5, 5π/4)
Answer:
d is the answer
Step-by-step explanation:
29+11+22=33+29=62 or 29+11=40+22=62
*.03 is the answer to this question
Answer:
B. 29.7
Step-by-step explanation:
All you have to do is find the area of the half circle (r² × 3.14 × ½) and subtract that from the initial area of the rectangle ( 9×4 ) After doing that it gives you 29.7ft².

those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below
that means, the squared variable is the "x", thus the form is

now, we know the vertex is at 0,1, and two x-intercepts of

thus

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation
