The equation of the parabola is:
---------------------------
The <em>equation </em>of a parabola of vertex (h,k) and focus (0,f) is given by:
- Vertex at the origin means that .
- Focus (0,6) means that
Thus, the equation of the parabola is:

Given,
m∠R = 37
m∠S = 50
m∠T = ?
m∠R + m∠S + m∠T = 180 (Sum
of angles in a triangle)
37 + 50 + m∠T = 180
87 + m∠T = 180
Subtract 87 from both sides of the equation
87 – 87 + m∠T = 180 – 87
m∠T = 93
Therefore the angles of the triangle, in order from smallest
to largest: ∠R, ∠S, ∠T
∠R is opposite ST
∠S is opposite TR
∠T is opposite SR
Therefore, the side lengths of the triangle in order from
shortest to longest: ST, TR, SR (Option C)
The top two answers are equivalent, while the bottom one is not. You would use distributive property in the parentheses. If both expressions are the same, they are equivalent
1 =25 times 1+8=33
2=25 times 2+8=58
3=25 times 3+8=83
4=25 times 4+8=108
5=25 times 5+8=133
B
10= 25times 10+8=258
C
233=25 times x+8
233=25x+8
233-8=25x
225=25x
225/25=25x/25
