1 x 4.5 = £4.50
1.60 x 4.5 = 7.20 euros ?
Answer:
1,3,4. For every 10 students there is 1 teacher. Another example would be 50 students to 5 teachers.
Answer:
(x + 1)² + (y - 6)² = 50
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.
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = 
with (x₁, y₁ ) = (- 1, 6) and (x₂, y₂ ) = (- 6, 1)
r = 
= 
= 
= 
(h, k ) = (- 1, 6 ), then
(x - (- 1))² + (y - 6)² = (
)² , that is
(x + 1)² + (y - 6)² = 50 ← equation of circle
