Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²
so given
center at (9,-8)
(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²
input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r
well, the equation is
(x-9)²+(y+8)²=1000
Your answer is -8. I did it out of order. My apology.
Answer: B. Cannot be determined
Explanation:
We can't use SAS since we don't have two pairs of proportional sides. We only know one pair of sides. This also rules out SSS as well since we'd need 3 pairs of proportional sides.
We can't use AA because we don't have two pairs of congruent angles.
Currently, we simply don't have enough information to determine if the triangles are similar or not.
Answer:
66. Assuming after you substituted 3 in place of x, you followed order of operations, or PEMDAS.
Step-by-step explanation:
6(2x) + 9x +3 = area
6 (2(3)) + 9(3) + 3 = area
6 x 6 + 27 + 3 = area
36 + 30 = 66
area = 66
Answer:
20%
Step-by-step explanation:
400/2000=0.2
0.2*100=20
