Work Shown:

This says that x is between 1 and 4; it can equal 1, but it can't equal 4.
To visually represent this, we'll have a closed circle at 1, an open circle at 4, with shading in between these circles. This is represented by graph B.
Answer:
Step-by-step explanation:
To evaluate x^6-x/4y when x=-4 and y =4
We get
-4^6-(-4)/4(4)
=4096+4/16
=4100/16
=256.25
The rate in feet per second is 4.4.
Answer:
Step-by-step explanation:
x^2=20
just square both sides and u get
x = 4.472135955
