Answer:
centre = (2, - 4 ), radius = 3
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 2)² + (y + 4)² = 9 ← is in standard form
with centre = (2, - 4 ) and r = 
= 3
1.059 should be the answer because it goes up 0.059 on each one
Answer:
180
Step-by-step explanation:
From basic rules of a triangle we know that the interior angles of a triangle have to add up to equal 180°
But here is a formula for future references for finding the sum of the interior angles
interior angle sum = (n-2)180
where n = number of sides
and here is an example:
a triangle has 3 sides so we plug in 3 for n
(3-2)180
3-2=1
1*180 = 180
so the interior angles add up to equal 180
The answer is 2/90
Multiply 2/10 by 1/9
This is because the first time there are 2 green marbles and ten marbles total but the second time he had already taken out a green marble so there is only 1 green marble left and 9 marbles total.
Hope this helps :)
