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
Answer:
B= 43
Step-by-step explanation:
B=19+(6)(4)
B=19+24
B=43
Step-by-step explanation:
Triangles RQP and RBC are congruent.
Letters R and P are the 1st and 3rd letters in RQP.
Letters R and C are the 1st and 3rd letters in RBC.
Hence line RP = line RC = line CR (D).
The answer is 6x^2 - 8x + 2
The answer is I don’t really know how to explain it but trust me it’s B: 8.1
