Let us find the slopes of the two lines
ax+by=c, slope m1 = -a/b
bx-ay=c, slope m2 = b/a
m1*m2 = (-a/b)(b/a) = -1
Therefore the two lines are perpendicular so the answer is D
Answer:
option D
congruent
Step-by-step explanation:
A)
A chord of a circle is a straight line segment whose endpoints both lie on the circle.
B)
parallel lines NEVER meet at a single point
C)
the segments are perpendicular to the circle
D)
Tangent segments to a circle from the same external point are congruent.
As,
if we make a right angle triangle from these tangent, these both will share same central leg as well as same other leg, radius.

Answer:
1093.96
Step-by-step explanation:
900(1+.05)⁴=1093.955625
Answer:
(1) 0.4207
(2) 0.7799
Step-by-step explanation:
Given,
Mean value,
Standard deviation,
(1) P(X ≥ 17.5) = 1 - P( X ≤ 17.5)
( By using z-score table )
= 0.4207
(2) P(14 ≤ X ≤ 18) = P(X ≤ 18) - P(X ≤ 14)
= 0.9918 - 0.2119
= 0.7799
