Concept explainers
(a)
To find: the shapes of line form by the graph with explanation.
(a)
Answer to Problem 42E
It formed a trapezoid, which is a quadrilateral with no side parallel.
Explanation of Solution
Given:
Concept used:
Graph can be draw using graphing calculator like Desmos graphing calculator.
The straight lines form an intersection with one another or it is parallel to each other.
Calculation:
The functions are
The graph of the functions is:
Hence, the shape formed a trapezoid, which is a quadrilateral with no side parallel.
(b)
To find: the conjecture about the equations of parallel lines.
(b)
Answer to Problem 42E
In the case the two parallel lines are
Explanation of Solution
Given:
Concept used:
Conjecture angle
Then the two lines are parallel to each other.
Calculation:
The conjecture is angle
Hence, In the case the two parallel lines are

- 2. Consider the following argument: (a) Seabiscuit is a thoroughbred. Seabiscuit is very fast. Every very fast racehorse can win the race. .. Therefore, some thoroughbred racehorse can win the race. Let us define the following predicates, whose domain is racehorses: T(x) x is a thoroughbred F(x) x is very fast R(x) x can win the race : Write the above argument in logical symbols using these predicates. (b) Prove the argument using the rules of inference. Do not make use of conditional proof. (c) Rewrite the proof using full sentences, avoiding logical symbols. It does not need to mention the names of rules of inference, but a fellow CSE 16 student should be able to understand the logical reasoning.arrow_forwardFind the inverse of the matrix, or determine that the inverse does not exist for: € (b) 7 -12 240 1 1 1 (c) 2 3 2 2 17 036 205 20 (d) -1 1 2 1 T NO 1 0 -1 00 1 0 02 (e) 1 0 00 0 0 1 1arrow_forward4.
