? the coordinates of a, b, c, and d are a (-6, 1), b (-9, 4), c (-1, 1), and d (-7, 6). how are ab←→ and cd←→ related? they are
balandron [24]
AB :
(-6,1)(-9,4)
slope = (4 - 1) / (-9 - (-6) = 3 / -3 = - 1
CD:
(-1,1)(-7,6)
slope = (6 - 1) / (-7 - (-1) = -5/6
different slopes....slopes are not negative reciprocals...means they are not perpendicular, parallel, or coincident. These lines will intersect at one point.
I believe the diameter would be 12
d=2r

since a whole circle is 360 degrees just subtract 259 from 360
Answer: Medication in Lexi's system on day t becomes,
Step-by-step explanation:
Since we have given that
Initial amount Sofia takes of a medicine = 10 mg
Concentration in blood decreases by a factor of one half every day.
So, it becomes,
According to question, four days later, it becomes,
We have given that Lexi takes 10 mg of the same medicine.
So, it becomes,
Hence, Medication in Lexi's system on day t becomes,

Answer:
- x = 95°
- y = 75°
- arc ABC = 150°
Step-by-step explanation:
The relevant relations are ...
- an inscribed angle is half the measure of the arc it intercepts
- opposite angles of an inscribed quadrilateral are supplementary
__
Using the second relation, ...
x = 180° -85° = 95°
y = 180° -105° = 75°
Using the first relation, ...
arc ABC = 2y = 2(75°) = 150°
