Answer:
(x + 1)² + (y - 1)² = 16
Step-by-step explanation:
Since the standard form for an equation of a circle is
<h3>
(x - h)² + (y - k)² = r²</h3>
The (h,k) are co-ordinate of your centre of circle, which in this case is (-1,1) and r is the radius of circle.
As we can see in the figure radius = 4units
<em>from centre(1,-2) to (1,-2)</em>
Put these into the equation
(x + 1)² + (y - 1)² = 4²
(x + 1)² + (y - 1)² = 16
Which question I don't see pics
Answer: 54
Step-by-step explanation:
First we add 17 plus 18 to dins total number of students I got 35
Then we make ratio
3/35
So we know we have total number of 630 kids then we make a ratio with no teacher so x
X/630
Lin both together then done ☑️
