Answer: 
Step-by-step explanation:
For this exercise you can use the following formula for calculate the slope:
In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:
Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:
Finally, evaluating, you get that the slope of this line is the following:
The first 5 outputs are:
As you can see, the outputs keep doubling each time we increment x by 1.
This can be written formally, observing that if you know the value of 
, the next value will be
So, again, we've shown that the next value is twice the previous one, so you have
The answer is the first two inequalities ........
For 1 multiply both sides by 3 which gives you 3y-y=12. Then combine like terms 2y=12. Lastly divide both sides by 2 and you get y=6. And for 3 first multiply both sides by 4 which gives you 6y-32=y+8. After that combine like terms 6y-y-32=8. Now add the equation together 5y=40 and then divide by 5 and get y=8
By definition, the volume of a sphere is given by:
V = (4/3) * (pi) * (r ^ 3)
where,
r: radius of the sphere.
Substituting we have:
V = (4/3) * (pi) * ((3) ^ 3) = 113.08 in ^ 3
answer
the best estimate for the volume of air in the balloon in cubic inches is
C. 113.1
