Let p be "it is raining" and q be "the track meet will be canceled."<br> write p-&gt;q in words
trasher [3.6K]

The statement for the logic \text{p}\rightarrow\text{q} is \fbox{\begin\\\ \text{If it is raining then the track meet will be cancelled}\\\end{minispace}}

Further explanation:

The logic given in the question is \text{p}\rightarrow\text{q}.

The logic \text{p}\rightarrow\text{q} is a symbol of implication.

Statement p is “It is raining” and the statement q is “The track meet will be canceled”.

The statement formed for the logic \text{p}\rightarrow\text{q} is called a compound statement.

The truth table for the logic \text{p}\rightarrow\text{q} is attached below.

From the table attached below  it is observed that there are four cases for the compound statement.

Case1:

If p statement is true and the q statement is true then the compound statement for \text{p}\rightarrow\text{q} is also true.

Case 2:

If p statement is true and the q statement is false then the compound statement for \text{p}\rightarrow\text{q} is false.

Case 3:

If p statement is false and the q statement is true then the compound statement for \text{p}\rightarrow\text{q} is true.

Case 4:

If p statement is false and the q statement is false then the compound statement for \text{p}\rightarrow\text{q} is true.

For a true statement it can also be said that it is a positive statement and for a false statement it can be said that it is a negative statement.

Statement p is given as “It is raining”, which is a positive statement or a true statement.

Statement q is given as “The track meet will be cancelled”, which is a positive statement or a true statement.

As per the table attached for the logic \text{p}\rightarrow\text{q} it is observed that the given statements p and q resembles with the case 1 as both of the statement are true.

So, the compound statement for \text{p}\rightarrow\text{q} is also a true statement.

The compound statement for the logic \text{p}\rightarrow\text{q} is as follows:

\fbox{\begin\\\ \text{If it is raining then the track meet will be cancelled}\\\end{minispace}}

Therefore, the compound statement for the logic \text{p}\rightarrow\text{q} is \fbox{\begin\\\ \text{If it is raining then the track meet will be cancelled}\\\end{minispace}}

A gust of wind forces a rock to fall off a cliff that's 20 feet high. This is represented by the function h(t) = –16t2 + 20, whe
Helga [31]

Answer: C.) 1.12 seconds

Step-by-step explanation:

Hi, to answer this question we have to substitute h=0 (when the rock hits the ground the height above it is 0) in the equation given:

h (t) = –16t2 + 20

Solving for t (time)

0= –16t2 + 20

16t2=20

t2=20/16

t=√1.25 =1.12 seconds (option C)

Feel free to ask for more if needed or if you did not understand something.
