A line is drawn so that it passes through the points (-3,0) and (1.4). What is the slope of the line?
vladimir2022 [97]

Answer: m=1

Step-by-step explanation:

For this exercise you can use the following formula for calculate the slope:

m=\frac{y_2-y_1}{x_2-x_1}

In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:

y_2=0\\y_1=4\\\\x_2=-3\\x_1=1

Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:

m=\frac{0-4}{-3-1}

Finally, evaluating, you get that the slope of this line is the following:

m=\frac{-4}{-4}\\\\m=1

Show that each of these conditional statements is a tautology by using truth tables. a) [¬p ∧ (p ∨ q)] → q b) [(p → q) ∧ (q → r)
nlexa [21]

Step-by-step explanation:

To show that a statement is a tautology using truth table - is to show that all the entries in the expression are truths T.

We can do this by taking each statement, expression by expression. For example, to show that

[~p ∧ (p ∨ q)] → q

is a tautology, knowing we have 3 columns, we have 2^3 = 8 rows. We start by putting putting truth values for p, q, and r respectively

Next, we find ~p, then find (p ∨ q), then find ~p ∧ (p ∨ q), before finally arriving at the required [~p ∧ (p ∨ q)] → q

TERMINOLOGIES AND SYMBOLS

- T means Truth

- F means False

- ~p means negation of p.

~p is F if p is T, and vice versa

- ∧ means conjunction.

p ∧ q is T only if p is T and q is T.

- ∨ means disjunction.

p ∨ q is T if either p or q is T.

- → is for conditional 'if then'

p → q is T if both p and q are T, or both p and q are F, or p is F and q is T, otherwise, it is F.

THE STEP BY STEP WORKINGS FOR THE STATEMENTS GIVEN ARE IN THE ATTACHMENT.

How do u solve P=IRT solve for t
Roman55 [17]
You said that                             P             =  I · R · T

Divide each side by  I · R :      P / (I·R)  =             T
