Given:
The objective is to find the slope of the straight line.
Explanation:
The general equation to find the slope is,

Let's consider two coordinates from the graph.

On plugging the values in the equation of slope,

Hence, the slope of the straight line is -5.
Density=mass/volume
given mass=120g and volume=200cm3
density=

or abot 0.6
the density is
We need to find the other base also in order for us to find out what the area of this is.
Answer:
(a) 
(b) 
(c) At 4 weeks, when both will be seeing an average of 3 hours of TV.
Step-by-step explanation:
a) For the students, they start at X(0)=5 h and ΔX=-0.5 h/week.
We can write

b) For the professors, they start at X(0)=1 h and ΔX=+0.5 h/week.
We can write

c) The seew which they will be watching the same amount of hours will be the 4th week.

The amount of hours will be

<span>Square root of 100 is a rational number. Because sqaure rooot 100 = 10. And, 10 can be written in the form rational number. Any number that can be written in the form of p/q where p and q are integers and q in not zero is called a rational number.</span>
