Answer:
The statement
is a tautology.
Step-by-step explanation:
We have the following statement 
A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.
The simple statements from the statement given are:
,
,
,
, and
with these you can construct the following truth table.
A tautology is a formula that is always true, it is true for every assignment of truth values to its simple components.
The last column contains only true values. Therefore, the statement is a tautology.
Answer:
r≈97.95
Step-by-step explanation:
r=C
2π=615.44
2·π≈97.95032
1) Take the perimeter and divide it by 4.
2) Take the answer from step 1 and square it (multiply by itself)
Its 96, if you need more math problems like this answered just ask me! :D
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
We have the equations in the standard form. Convert to the slope-intercept form:
<em>subtract 3x from both sides</em>

<em>add x to both sides</em>
<em>divide both sides by 3</em>

We need only two points to plot a graph of each function.

for x = 0 and for x = -3:


for x = 0 and for x = -3:
