A means an area
s side of the square, because of all sides are equal
then Area=s*s or Area=s²
so
A=9*9=81yd²
Start on -7 since it is the y intercept(b). 4/1 is the slope. So from seven you would go up 4 right 1.
is the logical or/disjunction symbol.
means "
or
". Disjunction is commutative, which means
is equivalent to
.
So if
represents
and
represents
, then
means
or
.
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.
