Answer:
it is A because when you look at the answer they don't make sense and there is no answer D
I would not normally stop to answer this question, mainly because
there is no question asked. It's just three statements.
I do have to stop here and leave a remark, however.
Math and Physics are closely enough related that I would not
have expected to see what I see here. Although the math in
this question is reasonable, the Physics is inexcusable.
A rainbow is always a part of a circle.
Rainbows are never parabolas.
You could never cut a parabola out of paper, and then
hold it up in front of you after a rainstorm, and match it
to the rainbow.
Answer:
x= (2/5)-(2y/5) (Im not sure if this is what you need but this is the answer simplified)
Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
Answer:
≈ 82 feet
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to calculate distance (d)
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Here the hypotenuse is the distance (d) between the 2 poles, hence
d² = 80² + 45² = 6400 + 2025 = 8425 ( take the square root of both sides )
d = 
≈ 82 feet ( to the nearest foot )
