Answer:
B (x-7<-6)
Step-by-step explanation:
x < 1
Answer:
((x+3)^2)/49 - (y^2)/36 = 1
Step-by-step explanation:
Answer:
x<_2
Step-by-step explanation:
Its the second answer choice.
3x<_6
Divide 3 by both sides and you get the answer.
we are given
we can seperate them
First function is
second function is
now, we can draw graph
and find intersection points
so, we can see that
intersection points are
(0,1) and (4,1)
so, solutions are

Answer:
C. -2.00 m/sec
Step-by-step explanation:
The average velocity on the interval [a, b] is found by ...
m = (s(b) -s(a))/(b -a)
One end of the interval remains constant here, so we can define 'd' so that the interval is [4, 4+d]. Then the average velocity is ...
m = (s(4 +d) -s(4))/((4 +d) -4)
m = (s(4+d) -s(4))/d
The attached table shows the average velocity values on the intervals required by the problem statement. Respectively, they are ...
-1.5 m/s, -1.7 m/s, -1.9 m/s, -1.99 m/s, 2.01 m/s, 2.1 m/s, 2.3 m/s, 2.5 m/s
We expect the instantaneous velocity at d=0 to be the average of the values at d=-0.01 and d=+0.01. We estimate the instantaneous velocity at t=4 seconds to be -2.00 m/s.
