Answer:
Step-by-step explanation:
A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any point of the circle and the centre is called the radius.
Let B be the centre of the circle
Let AB =r units be the radius ie., distance between A and B
where AC is the diameter of the circle
Answer:
k = 7
Step-by-step explanation:
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7
The answer would be 112.5 plz give me thanks and full rating PLZZZZZZ
The answer is C 7
Hope this helps
Answer:
= 2√6
Step-by-step explanation:
a² + b² = c²
1 + b² = 25
b² = 24
b = ±√24
b = ±2√6
We can forget about the minus answer because you cannot have a negative length. That does not make sense.
Please mark me brainliest.
