Answer:
Ray BA
Step-by-step explanation:
RAY BA
B IS THE POINT OF EMERGENCE OF RAY AND GOING IN THE DIRECTION BA.
Answer:
A
Step-by-step explanation:
The equation of the line that passes through the points (-9,-7) and (-12,-2) is
y = -5/3x-22
and
equation of the line that passes through the points (1, 9) and (6, 6) is
y = -3/5x+48/5
clearly it is not the same line,
(lines are not perpendicular)
(not parallel)
Answer
Let t be number of minutes since tap is opened
water is increased by 20 gallons of water per minute.
sugar increase rate of 3 pounds per minute
water :- W(t) = 350 + 10 t
sugar :- S(t) = 10 + 3 t
concentration
C(t) = 
at t = 15 minutes
C(15) = 
C(15) = 
C(15) = 0.11
at beginning t = 0 minutes
C(0) = 
C(0) = 
C(0) = 0.0286
C(15) > C(0)
hence, concentration is increasing as time is passing.
1/6. since one can't be divided by six into a whole #, it doesn't reduce.
