Concept explainers
a.
To explain: Why the concentration of acid is
Given:
The amount of pure acid added is
Formula used:
Calculation:
The total amount of solution is
Total amount of solution added is
Since the concentration of mixture is given by
Conclusion:
This is reason for the concentration of mixture to be
b.
To find: The equation of horizontal line.
The equation of horizontal line is
Given:
The amount of pure acid added is
Calculation:
From the graph given it is clear that a horizontal line is there.
It is parallel to
So, the equation will be
c.
To find: The amount of pure acid when the concentration is
The amount of pure acid using graph is
Given:
The amount of pure acid added is
Calculation:
The concentration of acid is
Substitute
Solve further for the value of
Conclusion:
The amount of pure acid using graph is

- Please help on both Part b) and c) below Thanksarrow_forwardfind the zeros of the function algebraically: f(x) = 9x2 - 3x - 2arrow_forwardRylee's car is stuck in the mud. Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lbarrow_forward
