Answer:
4/7
Step-by-step explanation:
Answer:
(−33)(−34) = 1122
n × ( n + 1 ) = 1122 This gives n 2 + 1 n = 1122 subtracting both sides by 1122 gives n 2 + 1 n − 1122 = 1122 − 1122 or n 2 + 1 n − 1122 = 0 1122 = 33 × 34 ( n − 33 ) × ( n + 34 ) = 0 n = 33 or n = − 34 Negative factors are asked for, so reject n = 33 The factors are − 33 and − 34
Answer:
Step-by-step explanation:
i think eq. of circle is
x²+y²-2x+4y-18=0
compare with x²+y²+2gx+2fy+c=0
center is (-g,-f) or (1,-2)
radius is √(g²+f²-c)=√((1)²+(-2)²-(-18))
=√(1+4+18)
=√23
15:2 would be the ans, if im not mistaken
