Answer:
x² + y² = 4
Step-by-step explanation:
We need to write the standard equation of circle with , centre (0,0) and radius 2 unit . The Standard equation of the circle ⭕ is ,
=> ( x - h)² + (y -k)² = r²
=> ( x -0)² + (y-0)² = 2²
=> x² + y² = 4 .
<h3>• Hence the equation of the circle is x² + y² = 4.</h3>
Answer:
$540
Step-by-step explanation:
29% : $156.60
156.60 ÷ 29/1 = $5.4
1% : $5.4
100% = 5.4 x 100
= $540
3x+2=11
(you need to isolate x, so step 1 is to subtract 2 from both sides.)
3x+2-2=11-2
3x=9
(then divide both sides by 3)
3x/3=9/3
x=3
