Given:
The function that represents how the amount of fuel changes as a function of distance flown is

where x represents miles flown, and f(x) represents the amount of fuel remaining.
To find:
The rate of change for this scenario.
Solution:
The slope intercept form of a linear function is
...(i)
Where, m is the slope or rate of change and b is the y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.
Answer: 1 & 4
Step-by-step explanation:
Just did it
Answer: Option 'A' is correct.
Step-by-step explanation:
In the binomial probability formula, we have

Here, n = number of events
x = number of trials
p = probability of success
q = probability of failure
x is the number of trials among which we decide the number of successes and number of failures.
So, Option 'A' is correct.
Answer:
Carlos graphed the perpendicular bisector of AB.
Step-by-step explanation:
Given a line segment AB drawn in a coordinate plane. The set of points that are the same distance from points A and B divides the line segment AB into two equal parts.
This line is referred to as the perpendicular bisector of AB.
Therefore, Carlos graphed the perpendicular bisector of AB.
Hi!
First of all, we can look and see that these sqaure roots are the same, so it's easy to add.
In square roots, if the number INSIDE the square root is the same, it stays that way for the answer .
So the equation is 9(square root) 5 + 4(square root) 5.
The numbers out the sqaure root can just be added. So 9+4 = 13.
Lastly just attach the sqaure root onto the 13
Final answer should be 13(square root)5
***use the actual symbol in place of (sqaure root)
I hope this helps!
