its B. 50°
Triangle Have 180°
- 180 - 90 = 90
- 90 × 2 = 180
Half of triangle Have 90°
The function f(x) = 5x² + 40x is a parabola. Then the vertex of the parabola will be at (–4, –80).
<h3>What is the parabola?</h3>
It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The function f(x) = 5x² + 40x
Then add and subtract 80, then we have
f(x) = 5x² + 40x + 80 – 80
f(x) = 5(x² + 8x + 16) – 80
f(x) = 5(x + 4)² – 80
The vertex of the parabola will be at (–4, –80).

Answer:
B
Step-by-step explanation:
since K is constant ( the same for every point) we can find k when given any point by dividing the y-coordinate by the x-coordinate.
Answer:
Light
Step-by-step explanation:
He is below the standard deviation limits for average or normal.
16-gon = 2,520 deg
2,520 divided by 16 = 157.5
157.5 deg
