Answer:
≈ 78.55 cm
Step-by-step explanation:
Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is
=
, that is
=
( cross- multiply )
110C = 8640 ( divide both sides by 110 )
C =
≈ 78.55 cm ( to 2 dec. places )
Pretty sure the answer is c :))
Hello, we need to solve this system, c being a real number.

y=y, right? So, it comes.

We can compute the discriminant.

If the discriminant is 0, there is 1 solution.
It means for 
And the solution is

If the discriminant is > 0, there are 2 real solutions.
It means 4(4-c) > 0 <=> 4-c > 0 <=> 
And the solution are

If the discriminant is < 0, there are no real solutions.
It means 4(4-c) < 0 <=> 4-c < 0 <=> 
There are no real solutions and the complex solutions are

Thank you.
Y = a |x-k|+h
a = slope it can be either vertical compression or vertical stretch
k = determines if a point should move right or left (x-axis)
h = determines if a point should move up or down (y-axis)
The answer to the question would be
y = - |x - 2.5|-7
