Answer:
(x + 2)² + (y - 1)² = 25
Step-by-step explanation:
radius: r² = (1 - (-3))² + (-2 - (-5))² = 16 + 9 = 25
r = 5
Circle: (x - h)² + (y - k)² = r²
center: (-2 , 1) h = -2 k = 1
(x + 2)² + (y - 1)² = 25
For dA in a circle, the r value varies , but its area is still rdrd(theta) but r (and theta) differs depending where the region is
and the regions could be any regions as long as it is a continuous region

Answer:
B
Step-by-step explanation:
check using Pythagorean theorem
8^2 = 5^2 + 7^2
64 = 25 + 49
64 = 74
No
<h3><u>S</u><u>olution</u></h3>
1). 1/3 + 1/5 = (5 + 3)/15
= 8/15. Ans.
2).
==> 3/5 - 1/6
= (3×5 - 5)/30
= (15 - 5)/30
= 10/30
= 1/3 Ans.
3).
==> 2/3 ÷ 3/4
= 2/3 × 4/3
= 8/9 Ans.
4).
==> 3/8 + 5/12
= (3×3 + 10)/24
= (9+10)/24
= 19/24 Ans.
5).
==> 5/16 - 3/32
= (5×2 - 3)/32
= (10-3)/32
= 7/32 Ans.
